RISK FACTORS

         An investment in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below before making a decision to invest in our common stock. Our business, operating results, financial condition or prospects could be materially and adversely affected by any of these risks and uncertainties. In that case, the trading price of our common stock could decline and you might lose all or part of your investment. In addition, the risks and uncertainties discussed below are not the only ones we face. Our business, operating results, financial performance or prospects could also be harmed by risks and uncertainties not currently known to us or that we currently do not believe are material. In assessing the risks and uncertainties described below, you should also refer to the other information contained in this prospectus before making a decision to invest in our common stock.

Risks Related to Our Business

We may not maintain our current rate of revenue growth.

        Our revenues have grown rapidly, increasing from $12.9 million in 2010 to $48.5 million in 2012, representing a compounded annual growth rate of 94%. Our continued revenue growth and the rate of our revenue growth depend largely on our ability to effectively and efficiently grow our membership, increase the number of members who pay for our products and services, increase the average revenue from our paying members and lengthen the time period existing and new members continue to pay for our products and services. We cannot assure you that we will be successful in continuing to expand our paying member base at the same rates, or at all. In addition, our revenue growth rate may decline if we are not successful in cross-selling new and existing products and services to our members, such as our consumer payments solutions, or in continuing to develop new products and services that members consider valuable.

        You should not rely on our historical rate of revenue growth as an indication of our future performance. If our growth rates were to decline significantly or become negative, it could adversely affect our financial condition and results of operations.

We have a history of cumulative losses and expect to have operating losses as we continue to grow our business.

        We experienced net losses of $3.5 million in 2010, $12.2 million in 2011 and $20.4 million in 2012. We expect our operating expenses to increase significantly over the next several years, which is likely to lead to additional losses. Therefore, we may not achieve profitability in the immediate future, if ever. In particular, we intend to continue to invest substantial resources in marketing to acquire new, paying members. We also intend to hire additional personnel in marketing, operations, sales and other areas of our business and to introduce new products, services and features, each of which will increase our expenses with no assurance that we will generate sufficient revenue to reduce our losses or achieve profitability. In addition, as we prepare to become a public company, and as a public company, we are incurring and will continue to incur additional significant legal, accounting and other expenses that we did not have as a private company.

We have a limited operating history in an evolving industry, which makes it difficult to evaluate our future prospects and may increase the risk that we will not be successful.

        We have a limited operating history, and because the market for accessing care online is rapidly evolving and has not yet reached widespread adoption, it is difficult for us to predict our future operating results. In addition, much of our growth has occurred over the last two years, which makes it difficult for us to predict the expected length of paid memberships, revenue per member, member acquisition costs and other key performance indicators for our business. You should consider our business and prospects in light of the risks and difficulties we may encounter in this rapidly evolving market. These risks and difficulties include those described in this prospectus and our ability to, among other things:

•

attract and retain members and maintain an appropriate family to caregiver ratio of active members;



•

encourage paying members to stay longer and return as paying members sooner after their paid membership lapses;

10

Table of Contents

•

cross-sell our products and services to our new and existing members and continue to develop and diversify our product offerings for members;



•

sell our services to employers and care-related businesses;



•

provide our members with superior user experiences;



•

motivate members to contribute additional, timely and accurate content to our marketplace;



•

anticipate and react to changes in technology and challenges from existing and new competitors;



•

maintain the strength and increase awareness of our brand; and



•

manage and grow our international operations in existing markets.

        Failure to adequately address these risks and difficulties could harm our business and cause our operating losses to grow. In addition, if the demand for online care does not develop as we expect, or if we fail to address the needs of this demand, our business will be harmed.

If the revenue generated by paying members differs significantly from our expectations, or if our membership acquisition costs increase, we may not be able to recover our membership acquisition costs or generate profits from these investments.

        We had $35.9 million in sales and marketing expenses in 2012 and $43.9 million in sales and marketing expenses during the nine months ended September 28, 2013. We expect to continue to make significant investments to acquire additional members, including advertising through television, online, local radio, direct mail, social media and other advertising campaigns. Our decisions regarding these investments are based on our anticipated marketing cost to acquire each additional paying member and our analysis of the revenue we believe we can generate per paying member over the expected lifetime of such membership. Currently, most of our paid memberships are monthly memberships, and the average paid membership length for our consumer matching solutions is approximately seven months. As a result, we must regularly replace paying members who allow their membership to lapse with new paying members either by converting existing non-paying members or by attracting new members to our service. Our anticipated member acquisition costs and our analysis of the revenue that we expect new paying members to generate over the life of the membership depends upon several estimates and assumptions, including lengthening paid memberships and increasing renewal rates, including conversion rates of existing members to paying members, future membership fees and our success in cross-selling existing and new products and services to members.

        If our estimates and assumptions regarding either our cost to acquire paying memberships or the revenue we can generate from those memberships over their lifetime prove incorrect, we may be unable to recover our member acquisition costs and our operating losses may increase. Similarly, if our member acquisition costs increase, the return on our investment may be lower than we anticipate irrespective of the revenue generated by new members. If we cannot generate profits from this investment, we may need to alter our growth strategy, and our growth rate and results of operations may be adversely affected.

Our business depends on the strength of our brand, which we have built by providing families and caregivers efficient, reliable and affordable services for finding quality caregivers and fulfilling jobs. If the services we provide fail to meet our members' expectations, the trust members have placed in our brand may be damaged, and we may be unable to maintain or expand our base of members and paying members.

        Trust in our brand is essential to the strength of our business. Member awareness, and the perceived value, of our brand depends largely on the success of our marketing efforts and our ability to provide a consistent, high-quality member experience. As a result, we must ensure that our new and existing members are satisfied with all of our products and services. Complaints or negative views of our products or services, caregivers or families, irrespective of their validity, could diminish members' confidence in and the use of our platform and adversely impact our brand.

11

Table of Contents

        In addition, our member experience extends beyond the products and services that we offer through our website and to the point of service. As a result, actions taken by caregivers and families, which are outside of our control, could have a significant impact on our brand, and any illegal or otherwise harmful acts, even if only by one or a small number of our members, may have a significant negative impact on our brand. If our efforts to promote and maintain our brand are not successful or if our member experience is not otherwise positive, our operating results and our ability to attract and retain members may be adversely affected.

        Furthermore, an adverse, public event resulting from the actions of a caregiver on a competitor's platform could adversely affect us—even if the caregiver has no relationship with our platform—and reduce consumer confidence in seeking caregivers through an online platform.

If we fail to manage our growth effectively, our business, operating and financial results may suffer.

        We have recently experienced, and expect to continue to experience, significant growth, which has placed, and will continue to place, significant demands on our management and our operational and financial infrastructure. We expect that our growth strategy will require us to commit substantial financial, operational and technical resources, and we expect that our marketing cost per paying member will increase in the near term. Continued growth also could strain our ability to maintain reliable service levels for our members, to enhance our product offerings, to develop and improve our operational, financial and management controls, to continue to strengthen our reporting systems and procedures and to recruit, train and retain highly skilled personnel. As our operations grow in size, scope and complexity, we will need to scale our systems and infrastructure accordingly and may determine we need to open additional offices, add more network capacity and make other capital investments, which will require significant expenditures and allocation of valuable management resources. If we fail to maintain the necessary level of discipline and efficiency, or if we fail to allocate limited resources effectively in our organization as it grows, our business, operating results and financial condition may suffer.

Our revenue and operating results could vary significantly from period to period and be unpredictable, which could cause the market price of our common stock to decline.

        Our operating results have fluctuated in the past, and may continue to fluctuate in the future, as a result of a variety of factors, many of which are outside of our control. As a result, comparing our revenue and operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance.

        In addition, we generally experience some seasonality fluctuations in our financial results due to heightened demand for caregivers from families at the beginning of the school year and at the beginning of the calendar year. Accordingly, purchases of subscriptions for our consumer matching solutions generally increase in the first and third quarters compared to the second and fourth quarters. Although historically our revenue has increased in each quarter as we have added members, in the future this seasonality may cause fluctuations in our financial results. In addition, other seasonality trends may develop, and the existing seasonality and consumer behavior that we experience may change.

        We have based our current and projected future expense levels on our operating plans and sales forecasts, and our operating costs are relatively fixed in the short term. As a result, we may not be able to reduce our costs sufficiently to compensate for an unexpected shortfall in revenue, and even a small shortfall in revenue could disproportionately and adversely affect our financial results for a given quarter.

        It is possible that our operating results in some periods may be below market expectations. This would likely cause the market price of our common stock to decline. In addition to the other risk factors listed in this section, our operating results may be affected by a number of factors, including:

•

fluctuations in demand for our products and services;



•

fluctuations in sales cycles for our products and services;



•

general economic conditions in our domestic and international markets;



•

our ability to develop and introduce new products and product enhancements that are attractive to our members;



•

the mix of monthly memberships and annual memberships, as the amount of revenue recognized per month on an annual membership is less than a monthly membership;



•

member acceptance of new product introductions;



•

our ability to sell our services to employers and care-related businesses;



•

any significant changes in the competitive dynamics of our markets, including new entrants or substantial discounting of products;



•

any decision to increase or decrease operating expenses in response to changes in the marketplace or perceived marketplace opportunities;



•

our ability to derive benefits from our investments in sales, marketing, engineering or other activities;



•

volatility in our stock price, which may lead to higher stock compensation expenses; and



•

unpredictable fluctuations in our effective tax rate due to disqualifying dispositions of stock from our stock incentive plan, changes in the valuation of our deferred tax assets or liabilities, changes in actual results versus our estimates or changes in tax laws, regulations, accounting principles or interpretations thereof.

We depend on highly skilled personnel to grow and operate our business, particularly our chief executive officer, and if we are unable to hire, retain and motivate our personnel, we may not be able to grow effectively.

        Our future success will depend upon our continued ability to identify, hire, develop, motivate and retain highly-skilled personnel. Our ability to execute efficiently depends upon contributions from all of our employees, in particular our senior management team. Key institutional knowledge remains with a small group of long-term employees and directors whom we may not be able to retain. We do not have employment agreements other than offer letters with any key employee, including our chief executive officer, and we do not maintain key person life insurance for any employee other than our chief executive officer. In addition, from time to time, there may be changes in our senior management team that may be disruptive to our business. If our senior management team, including any new hires that we may make, fails to work together effectively and to execute our plans and strategies on a timely basis, our business could be harmed. Our growth strategy also depends on our ability to expand and retain our talent pool. Identifying, recruiting, training and integrating qualified individuals requires significant time, expense and attention. In addition to hiring new employees, we must continue to focus on retaining our best talent. Competition for these resources in the Boston area, where our headquarters is located, is intense. If we are not able to effectively increase and retain our talent, our ability to achieve our strategic objectives will be adversely impacted, and our business will be harmed.

        We believe that our culture has the potential to be a key contributor to our success. As we grow, if we do not continue to develop our corporate culture it could harm our ability to foster the innovation, creativity and teamwork we believe we need to support our growth.

13

        Finally, we utilize off-shore resources through third parties over whom we have limited control to assist us in developing certain products and features. If any of these third parties terminates their relationship with us or fails to provide adequate services, it could cause delays in our release of new product offerings and/or features and harm our business.

The number of our registered members is significantly higher than the number of our paying members and substantially all of our revenue is derived from our paying members.

        The number of registered members in our marketplace is significantly higher than the number of paying members because some members choose to register, but not become paying members, and others become paying members, but choose not to renew their paid memberships. If we are not able to attract new registered members, convert registered members to paying members or retain our paying members for a longer period of time our business may not grow as fast as we expect, which will harm our operating and financial results and may cause our stock price to decline. Therefore, we must provide features and products that demonstrate the value of our marketplace to our members and motivate them to become paying members. If we fail to successfully motivate our members to do so, our business and operating results could be adversely affected.

Our international operations are subject to increased challenges and risks.

        In 2012, we launched our platform in the United Kingdom and Canada, and we acquired Besser Betreut GmbH, or Betreut, in Germany. While we intend to focus most of our international efforts on growing our existing international markets, we also may expand our international operations in the future. We have an even more limited operating history as a company outside the United States, and our ability to manage our business and conduct our operations internationally requires considerable management attention and resources and is subject to the particular challenges of supporting a rapidly growing business in an environment of multiple languages, cultures, customs, legal systems, regulatory systems and commercial infrastructures. This international expansion has required us, and will continue to require us, to invest significant funds and other resources. International expansion also subjects us to risks that we have not previously faced, including risks associated with:

•

recruiting and retaining talented and capable employees in foreign countries;



•

providing products and services across a significant distance, in different languages and among different cultures, including potentially modifying our solutions and features to ensure that they are culturally relevant in different countries;



•

compliance with applicable foreign laws and regulations, which, in certain areas such as privacy and data protection, may be more restrictive than U.S. laws and regulations;



•

compliance with anti-bribery laws, including without limitation compliance with the Foreign Corrupt Practices Act and the United Kingdom Bribery Act;



•

currency exchange rate fluctuations; and



•

higher costs of doing business internationally.

        If our revenue from our international operations does not exceed the expense of establishing and maintaining these operations, our business and operating results will suffer.

Many individuals are using devices other than personal computers to access the Internet. If users of these devices do not widely adopt solutions we develop for these devices, our business could be adversely affected.

        The number of people who access the Internet through devices other than personal computers, including personal digital assistants, smart phones and handheld tablets, has increased dramatically in the past few years and is projected to continue to increase. If we are unable to develop mobile solutions to meet the needs of our users, our business may not grow as fast as we expect, which will harm our operating and financial results and may cause our stock price to decline. Additionally, as new devices and new platforms are continually being released, it is difficult to predict the problems we may encounter in developing versions of our solutions for use on these alternative devices, and we may need to devote significant resources to the creation, support and maintenance of such devices. In the future, we may encounter difficulties integrating our mobile app into mobile devices or we may experience problems in our relationships with providers of mobile operating systems or mobile application download stores, such as those of Apple or Google. It is also possible that our applications could receive unfavorable treatment compared to the promotion and placement of competing applications, such as the order in which our products are listed in the Apple App Store. Any of these events could adversely affect our growth and our results of operations.

We depend on search engines and job board sites to attract a significant percentage of our members, and if those businesses change their ranking or listings practices, algorithms or increase their pricing, it could impact our ability to attract new members.

        Many of our members locate our websites through search engines, such as Google, Yahoo! and Bing. Search engines typically provide two types of search results, algorithmic and purchased listings, and we rely on both types. Algorithmic listings cannot be purchased and are determined and displayed by a set of formulas designed by the search engine. Search engines revise their algorithms from time to time in an attempt to optimize search result listings. If the search engines on which we rely for algorithmic listings modify their algorithms in a manner that reduces the prominence of our listing, fewer potential members may find and click through to our websites. Additionally, our competitors' search engine optimization efforts may result in their websites receiving greater prominence in search result listings than ours, which could also reduce the number of potential members that visit our websites. We have experienced fluctuations in the prominence of our search result listings in the past and we anticipate fluctuations in the future. In addition, costs for purchased listings on search engines have increased in the past and may continue to increase in the future. Price increases could reduce the number of potential members that visit our websites and increase our costs. Any reduction in the number of users directed to our websites from search engines would harm our business and operating results.

        Job board sites are also an important source of our caregiver acquisition efforts. We derive much of that volume from organic search listings within those job boards. Should those job board aggregators deny our listings within their organic search listings, we would have to find alternative paid sources to acquire caregivers, which would increase our acquisition costs.

Our business may be harmed if users view our marketplace as primarily limited to finding full-time caregivers for children.

        Our membership growth and engagement rates could be adversely affected if consumers perceive the utility of our marketplace to be limited to finding full-time caregivers for children. Despite the breadth of care needs that can be met through our platform, including after school care, occasional babysitting, senior care, pet care, tutoring and housekeeping, approximately 35% of job postings in 2013 were for full-time child caregivers. In addition, our convenience payments product, which may be useful to families who employ any type of caregiver part-time or full-time, child care or senior care, is still in the early stages of adoption among our membership base and we cannot be certain what the rate of adoption will be or if enough of our users will find it sufficiently useful for us to continue to support. If families and caregivers

15

Table of Contents

fail to utilize the breadth of the family care and other services available through our marketplace, our membership growth and engagement rates could be negatively impacted, and our business will be harmed.

If we fail to expand and increase adoption of our consumer payments solutions, our results of operations and competitive position will suffer.

        As part of our growth strategy, we intend to grow our consumer payments solutions. Since our acquisition of Breedlove & Associates, L.L.C., or Breedlove, in August 2012, we have offered Care.com HomePay, a household employer payroll and tax product. Although an increasing percentage of our members are using HomePay, our growth and results of operations will be adversely affected if this trend does not continue. We also recently introduced a convenience payments product that allows families to make electronic payments to their caregivers using our mobile or desktop applications, and we intend to develop other payment and financial solutions to offer to our members as we expand our offerings and services. When we develop a new product, we typically incur expenses and expend resources upfront to market, promote and sell the new offering. Therefore, these new products must achieve high levels of market acceptance in order to justify the amount of our investment in developing and bringing them to market. If we fail to increase adoption of HomePay, or our convenience payments product or any other payments solutions we may offer do not achieve adequate acceptance in the market, our competitive position will be impaired, and our revenues could decline.

Our independent registered public accounting firm has advised us that it has identified a material weakness in our internal control over financial reporting. If our internal control over financial reporting or our disclosure controls and procedures are not effective, we may not be able to accurately report our financial results, prevent fraud or file our periodic reports in a timely manner, which may cause investors to lose confidence in our reported financial information and may lead to a decline in our stock price.

        Our independent registered public accounting firm has not conducted an audit of our internal control over financial reporting. However, in connection with the preparation of the registration statement of which this prospectus forms a part, our independent registered public accounting firm discovered errors in our financial statements related to the accounting for intangible assets. Specifically, we erroneously recognized impairment charges related to certain acquired intangible assets that should not have been impaired and determined periodic amortization using inappropriate economic useful lives. The effect of these errors was material to our financial statements. As a result of these items, we concluded that a material weakness in our internal control over financial reporting existed as of December 31, 2012. A "material weakness" is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weakness that was identified related to our lack of resources within our finance function required to analyze and account for complex non-routine transactions in a timely manner.

        Since January 1, 2013, we have taken steps to build a more experienced accounting and finance organization, including hiring a new chief financial officer, senior vice president of finance, assistant controller and senior accountant, and designing and implementing improved processes and controls. While we believe we have remediated the material weakness identified for fiscal 2012, we may identify additional related or unrelated material weaknesses or significant deficiencies in the future. If our internal control over financial reporting or our disclosure controls and procedures are not effective, we may not be able to accurately report our financial results, prevent fraud or file our periodic reports in a timely manner, which may cause investors to lose confidence in our reported financial information and may lead to a decline in our stock price.

        In addition, implementing any appropriate changes to our internal controls may distract our officers and employees, entail substantial costs to implement new processes and modify our existing processes and take significant time to complete. Moreover, any such changes do not guarantee that we will be effective in maintaining the adequacy of our internal controls, and any failure to maintain that adequacy, or

16

Table of Contents

consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and harm our business. Furthermore, investors' perceptions that our internal controls are inadequate or that we are unable to produce accurate financial statements on a timely basis may harm our stock price and make it more difficult for us to effectively market and sell our products and services to new and existing customers, particularly our payroll, tax and compliance products and services.

Data security and integrity are critically important to our business, and breaches of security, unauthorized disclosure of information about our members, denial of service attacks or the perception that member information is not secure could result in a material loss of business, substantial legal liability or significant harm to our reputation.

        We collect, process and store a large amount of consumer information, including financial information and sensitive personal information. This data is often accessed through transmissions over public and private networks, including the Internet. Despite our physical security measures, implementation of technical controls and contractual precautions designed to identify, detect and prevent the unauthorized access, alteration, use or disclosure of our data, there is no guarantee that these measures or any other measures can provide absolute security. Systems that access or control access to our services and databases may be compromised, as a result of criminal activity, negligence or otherwise. Threats may derive from human error, fraud or malice on the part of employees or third parties, or may result from accidental technological failure. Several recent, highly publicized data security breaches and denial of service attacks at other companies have heightened consumer awareness of this issue and may embolden individuals or groups to target our systems. Unauthorized disclosure or use, or loss or corruption, of our data or inability of our members to access our systems could disrupt our operations, subject us to substantial legal liability, result in a material loss of business, and significantly harm our reputation.

        We are subject to diverse laws and regulations in the United States and foreign countries mandating notification to affected individuals in the event that personal data (as defined in the various governing laws) is accessed or acquired by unauthorized persons. In the United States, federal and state laws provide for more than 40 diverse notification regimes, all of which we are subject to. Germany also has breach notification laws, and the new laws being debated in Europe propose introducing a general mandatory breach notification requirement with which we would have to comply. Complying with such numerous and complex regulations in the event of unauthorized access would be expensive and difficult, and failure to comply with these regulations could subject us to regulatory scrutiny and additional liability.

We may continue to make acquisitions, which could require significant management attention, disrupt our business, result in dilution to our stockholders, and adversely affect our financial results.

        As part of our business strategy, we have made, and may in the future make, acquisitions to add specialized employees, complementary companies, products or technologies. For example, in the last 18 months, we acquired Betreut, Breedlove and Parents in a Pinch, Inc. (now known as Care Concierge, Inc.), or PIAP. The identification of suitable acquisition candidates can be difficult, time-consuming and costly, and we may not be able to successfully complete identified acquisitions. Acquisitions may also involve the entry into geographic or business markets in which we have little or no prior experience. Moreover, the anticipated benefits of any acquisition, investment or business relationship may not be realized or we may be exposed to unknown liabilities. For any such transaction, we may:

•

issue additional equity securities that would dilute our stockholders;



•

use cash that we may need in the future to operate our business;



•

incur debt on terms unfavorable to us or that we are unable to repay;



•

incur large charges or expenses or assume substantial liabilities;



•

become subject to new laws and regulations about which we have limited prior experience or knowledge;



•

encounter difficulties retaining key employees of the acquired companies; and



•

become subject to adverse tax consequences, substantial depreciation or deferred compensation charges.

        Any of these risks could harm our business and operating results. In addition, for legal, technical or business reasons, we may not be able to successfully assimilate and integrate the business, technologies, solutions, personnel or operations of any company we acquire as quickly or fully as we would like. The integration of any acquired company may require, among other things, coordination of administrative, sales and marketing, accounting and finance functions, harmonization of legal terms and privacy policies and expansion of information and management systems.

We may not timely and effectively scale and adapt our existing technology and network infrastructure to ensure that our platform is accessible, and our business is subject to risks of events outside of our control.

        Our members access information through our websites and mobile apps. Our reputation and ability to acquire, retain and serve our members depend upon the reliable performance of our websites and mobile apps and the underlying network infrastructure. We have previously experienced, and may experience in the future, service disruptions, outages and other performance problems due to a variety of factors, including infrastructure changes, human or software errors, computer viruses or physical or electronic break-ins, denial of service attacks, capacity constraints and fraud or security violations. In some instances, we may not be able to identify the cause or causes of these performance problems within an acceptable period of time. It may become increasingly difficult to maintain and improve the availability of our platform, especially during peak usage times and as our solutions become more complex and if our user traffic increases. If our platform is unavailable when users attempt to access it or it does not load as quickly as they expect, users may use other services and may not return to our platform as often in the future, or at all. This would negatively impact our ability to attract users and increase engagement on our website and mobile apps. We expect to continue to make significant investments to maintain and improve the availability of our platform and to enable rapid releases of new features and products. To the extent that we do not effectively address capacity constraints, upgrade our systems as needed and continually develop our infrastructure to accommodate actual and anticipated changes in our business and in our technology, our business and operating results may be harmed.

        Substantially all of our communications, network and computer hardware used to operate our website at www.care.com are co-located in a single facility in Ashburn, Virginia. We do not own or control the operation of this facility. Our systems and operations are also vulnerable to damage or interruption from tornadoes, floods, fires, power losses, telecommunications failures or acts of war. For example, a significant natural disaster, such as a major snowstorm or flood, could have a material adverse impact on our business, operating results and financial condition, and our insurance coverage may be insufficient to compensate us for such losses that may occur. In addition, acts of terrorism could cause disruptions in our business or the economy as a whole.

        We have implemented disaster recovery procedures that allow us to move our platform to a back-up data center in the event of a catastrophe. However, these procedures do not yet provide a real time back-up data center. Therefore, if our primary data center shuts down, there will be a period of time that our platform will remain unavailable while the transition to a back-up data center takes place.

Interruptions or delays in service arising from our third-party vendors could impair the delivery of our service and harm our business.

        We rely in part upon third-party vendors to provide our convenience payments product and other services upon which we rely, including data center and Internet infrastructure services, credit card and payment processing services, background checking services, email management and delivery services, customer relationship management services and other services critical to our business. The operation of our product and service offerings could be impaired if the availability of these services is interrupted or limited in any way. We have contractual relationships with these parties but do not have physical control over their daily operations, which increases our vulnerability to problems with the services they provide. If any of these third-party service providers terminates their relationship with us, or does not provide an

18

Table of Contents

adequate level of service to our members, it would be disruptive to our business as we seek to replace the service provider or remedy the inadequate level of service.

        In addition, these service providers are vulnerable to damage or interruption from tornadoes, floods, fires, power loss, telecommunications failures and similar events. They also are subject to break-ins, sabotage, acts of vandalism, the failure of physical, administrative, and technical security measures, terrorist acts, human error, financial insolvency and other unanticipated problems or events. The occurrence of any of these events could result in interruptions in our service and unauthorized access to, or alteration of, the content and data contained on our systems and the content and data that these third-party vendors store and deliver on our behalf.

        We have experienced, and expect to continue to experience, interruptions and delays in service and availability for such elements. Any errors, failures, interruptions or delays experienced in connection with these third-party technologies and information services could negatively impact our relationship with our members, our brand and reputation and our ability to attract, retain and serve our members.

If we or our service providers fail to process payment transactions effectively and accurately or fail to protect against potential fraudulent activities relating to payment transactions, we may incur expenses and suffer reputational harm.

        We offer household employer payroll and tax services through our subsidiary Breedlove. We also recently introduced an electronic payments solution through a third-party payments processor that allows families to make electronic payments to their caregivers through our website and mobile apps. It is possible that we or our service provider may make errors in processing payments or that funds may be misappropriated due to fraud. We may also make errors in calculating and remitting taxes to the Internal Revenue Service. In addition, the online tax preparation, payroll administration and online payments industries have increasingly been subject to fraudulent activities by third parties.

        In addition to any direct damages and potential fines we may incur as a result of payment processing errors or fraud relating to our payments products, negative publicity or a loss of confidence regarding these services could harm our business and damage our brand.

We may not be able to compete successfully against current and future competitors.

        We are and will continue to be faced with many competitive challenges, any of which could adversely affect our prospects, results of operations and financial condition.

        With respect to our consumer matching solutions, we compete for families, caregivers, employers and care-related businesses with traditional offline consumer resources, online job boards and other, online care marketplaces. We also compete for a share of care-related businesses' overall recruiting and advertising budgets with traditional, offline media companies and other Internet marketing providers. Our principal competitors are Craigslist, a "free to consumer" website, and Sittercity, Inc., an online care specific marketplace. In the consumer payments market, our convenience payments product competes with other payment solutions such as PayPal and Google Payments, and HomePay competes with similar products offered by 4nannytaxes.com and GTM Payroll Services. In addition, we may in the future be subject to competition from companies that operate other online marketplaces and that decide to expand into the online care market or other established companies that decide to expand into the consumer payments market. These potential competitors may be larger and have more resources than we do, may enjoy substantial competitive advantages, such as greater name recognition, longer operating histories and larger marketing budgets, as well as substantially greater financial, technical and other resources. As a result, these potential competitors may be able to respond more quickly and effectively than we can to new or changing opportunities or technologies.

        To compete effectively for members, we must continue to invest significant resources in marketing and in the development of our products and services to enhance their value. To compete effectively for revenue from employers and care-related businesses, we must continue to invest in marketing and in growing our membership. Failure to compete effectively against our current or future competitors could result in loss of current or potential members, which could adversely affect our margins, and prevent us from achieving or maintaining profitability. We cannot assure you that we will be able to compete effectively for members in the future against existing or new competitors, and the failure to do so could result in loss of existing or potential members, reduced membership revenue, increased marketing or selling expenses or diminished brand strength, any of which could harm our business.

We may incur liability or other expenses if members do not meet the expectations of other members they connect with through our platform, if caregivers or other users of our services engage in inappropriate, harmful or illegal conduct, or if we do not notify our members of alleged inappropriate or illegal conduct.

        Even though U.S. courts have held that online services companies are not responsible for the actions of their website users in many circumstances, and our terms of use state that any screening we perform on families and caregivers is limited, there is a low tolerance for failure when seeking care for a loved one. Therefore, families and caregivers may seek damages from us if a caregiver or family does not meet their expectations or causes them harm. These claims also may be brought under foreign laws, which often do not provide the same protections for online services companies as in the United States. Even if these claims do not result in liability to us, they may result in significant investigation or defense costs, as well as negative publicity. In addition, because there is a particularly low tolerance for failure when seeking care for a loved one, any such claims, events or publicity could have a significant adverse effect on our reputation and brand. Any of these results, particularly damages to our brand and reputation, could adversely affect our financial condition, business and operating results.

        Our subsidiary PIAP provides back-up child and elder care to families by directly assigning caregivers, some of whom are PIAP employees, to families in need of temporary care. The caregivers and families involved in these transactions are not required to be members of our consumer matching solutions. To the extent that a caregiver provided through our back-up services does not meet the expectations of a family or causes harm, we may be subject to claims from that family or from the employer that subscribed to this service and offered it as an employee benefit to the family.

        From time to time, we become aware of information relating to our members through complaints from other members, publicly available sources or otherwise, which results in our removal of the member from our marketplace. Because of the complex legal and regulatory environment in which our business operates, we generally do not advise other members when we decide to remove a particular member and, when we do advise members that we have removed a member, we generally do not tell them the reason for removal. As a result, a member who hires a caregiver through our platform may not be aware that the caregiver has subsequently been removed from our marketplace or the reason the caregiver was removed, and may seek to make a legal claim against us for failure to notify them of the removal or the reason for the removal. Any such claims, whether or not meritorious, or any claim by a caregiver that he or she should not have been so removed, may be a distraction to management, result in our incurring costs to defend the claim or otherwise harm our business and reputation.

Adverse economic conditions may adversely impact our business.

        Our business depends on the overall demand for care. Our prospective members' employment and income impact their demand for care. Increased unemployment or a reduction in labor force participation could reduce the number of dual-income families—a key component of our target market—and therefore the number of families seeking care. In addition, if consumer spending is reduced due to a weak economy, families may decrease spending on care services they believe to be non-essential, such as housekeeping and tutoring, or reduce or eliminate certain activities that typically require the services of our caregivers, such

20

Table of Contents

as date nights that require babysitters and vacations that may require pet sitters. As a result, weakened macroeconomic conditions could decrease the traffic on our platform, reduce sales of our products and services and delay adoption of new offerings.

If we require additional funds from outside sources in the future, those funds may not be available on acceptable terms, or at all.

        We may require additional funds from outside sources in the future, and we may not be able to obtain those funds on acceptable terms, or at all. If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any debt or additional equity financing that we raise may contain terms that are not favorable to us or our stockholders.

        If we do not have, or are not able to obtain, sufficient outside funds, we may have to delay development of new product offerings. If we are unable to raise adequate funds, we may have to liquidate some or all of our assets, or delay, reduce the scope of or eliminate some or all of our development programs. We also may have to reduce marketing or other resources devoted to our products or cease operations. Any of these actions could harm our operating results.

We use, store and, in some instances, share information collected from or about our members and site visitors and their devices, which may subject us to governmental and industry regulation and other legal obligations related to privacy, and our actual or perceived failure to comply with such obligations could harm our business.

        We receive, store and process information from and about our members and website visitors and their devices, as well as information about HomePay and back-up care users, including name, contact information, and in some cases sensitive personal information, such as credit card numbers, tax return information, bank account numbers, social security numbers and other personal information such as criminal background information. In addition, our service enables our members to direct us to share information, including personal and background information, with other members and with third parties.

        Diverse legal and industry requirements in the regions where our members and site visitors reside may apply to our collection, use, storage and sharing information about such individuals, including to the extent that our members choose to share data about themselves or family members in connection with potential employment in the home setting. The scope of these privacy and data protection obligations are changing in substantial and unpredictable ways, subject to differing interpretations, and may be inconsistent between different regions or conflict with other rules.

        Some industry requirements subject us to payment card association operating rules, certification requirements and rules, including the Payment Card Industry Data Security Standard, or PCI DSS, a security standard with which companies that collect, store or transmit certain data regarding credit and debit cards, credit and debit card holders, and credit and debit card transactions are required to comply. Our failure to comply fully with the PCI DSS may violate payment card association operating rules, federal and state laws and regulations, and the terms of our contracts with payment processors and merchant banks. Such failure to comply fully may also subject us to fines, penalties, damages and civil liability, and may result in the loss of our ability to accept credit and debit card payments. In addition, there is no guarantee that PCI DSS compliance will prevent illegal or improper use of our services or the theft, loss or misuse of data pertaining to credit and debit cards, credit and debit card holders and credit and debit card transactions.

        We strive to comply with all applicable laws, policies, legal obligations and industry requirements relating to privacy and data protection, to the extent reasonably possible. However, it is possible that these obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other rules or our practices. Any failure or perceived failure by us to comply with our posted privacy policies, our privacy-related obligations to users or other third parties, or any other

21

Table of Contents

privacy-related legal obligations, may result in governmental enforcement actions, litigation or public statements against us by consumer advocacy groups or others and could cause our members and customers to lose trust in us, which could have an adverse effect on our business. Additionally, if third parties we work with, such as customers, vendors or developers, violate applicable laws, their contractual obligations to us or our policies, such violations may also put our members' information at risk and could in turn have an adverse effect on our business.

        Complying with existing and proposed laws, regulations and industry standards applicable to the collection, use, storage and sharing of data about our members and site visitors can be costly and can delay or impede the development of new products, result in negative publicity and reputational harm, increase our operating costs, require significant management time and attention, increase our risk of non-compliance and subject us to claims or other remedies, including fines or demands that we modify or cease existing business practices.

Our business is subject to a variety of U.S. and foreign laws, some of which are unsettled and still developing and which could subject us to claims or otherwise harm our business.

        Federal, state, municipal and/or foreign governments and agencies have adopted and could in the future adopt, modify, apply or enforce laws, policies and regulations covering user privacy, data security, unfair and deceptive practices, payment processing, tax preparation and/or the collection, use, maintenance, processing, transfer, storage and/or disclosure of data associated with a unique individual, including in connection with potential employment and other activities. The regulatory environment for many of these laws is very unsettled in the United States and internationally, especially as it applies to the products and services we offer and to the operation of our business generally.

        Our operations are subject to numerous laws that regulate privacy, data security and the use of consumer background information. Certain of these laws provide for civil and criminal penalties for the unauthorized release of, or access to, this protected information or for not adopting processes or procedures for handling reported inaccuracies in this protected information. For example, in the United States we acquire information about our members from consumer credit reporting agencies and other third-party sellers of public data about unique individuals. We use this information in an effort to verify the accuracy of the information members provide about themselves and to further our business objective to maintain a trusted online community for our members. We also facilitate the sharing of third-party consumer reports and criminal background checks between members at the direction of the individual who is the subject of the report. The Fair Credit Reporting Act, or the FCRA, applies to consumer credit reporting agencies as well as data furnishers and users of consumer reports, as those terms are defined in the FCRA. The FCRA promotes the accuracy, fairness and privacy of information in the files of consumer reporting agencies that engage in the practice of assembling or evaluating information relating to consumers for certain specified purposes, including for employment. The FCRA limits the distribution and use of consumer reports and establishes consumer rights to access and dispute their own credit files, among other rights and obligations. Members who access consumer reports about job applicants via our service expressly agree to follow the FCRA requirements for employers. Violation of the FCRA can result in civil and criminal penalties. The U.S. Federal Trade Commission, the Consumer Financial Protection Bureau, and the State Attorneys' General, acting alone or in cooperation with one another, actively enforce the FCRA as do private litigants. Many states have enacted laws with requirements similar to the FCRA. Some of these laws impose additional, or more stringent, requirements than the FCRA.

        In addition, the payment processing and tax preparation industries are receiving heightened attention from federal and state governments. New legislation, regulation, public policy considerations, litigation by the government or private entities or new interpretations of existing laws may subject us to additional legal or regulatory oversight or obligations, restrict the types of products and services that we can offer or the prices we can charge, or otherwise cause us to change the way we operate our payment processing and tax preparation businesses or offer our payment processing and tax products and services. This in turn may

22

Table of Contents

increase our cost of doing business and limit our revenue opportunities. In addition, if our practices are not consistent with current or new interpretations of existing laws, we may become subject to lawsuits, penalties and other liabilities.

        If we are not able to comply with existing or new laws or regulations or if we become liable under these laws or regulations, we could be directly harmed, and we may be forced to implement new measures to reduce our exposure to this liability. This may require us to expend substantial resources or to discontinue certain solutions, which would negatively affect our business, financial condition and results of operations. In addition, the increased attention focused upon liability issues as a result of lawsuits and legislative proposals could harm our reputation or otherwise impact the growth of our business. Any costs incurred as a result of this potential liability could harm our business and operating results.

As we develop and sell new products, services and features, we may be subject to additional and unexpected regulations, which could increase our costs or otherwise harm our business.

        As we develop and sell new products, services and features to our members, we may become subject to additional laws and regulations, which could create unexpected liabilities for us, cause us to incur additional costs or restrict our operations. For example, we offer our convenience payments product to our members through a third party. If, in the future, we provide this product directly to our members, we would be subject to complex financial regulations. We may also become subject to financial regulations as we develop additional payment and financial solutions for our members. In addition, if we expand our offerings to include more personalized services, we may become subject to various laws and regulations relating to the protection of children, seniors and/or prospective employees.

        Our failure to accurately anticipate the application of laws and regulations that governmental organizations or others may claim are applicable to new products and services we may offer, or other failure to comply, could create liability for us, result in adverse publicity or cause us to alter our business practices, which could cause our revenue to decrease, our costs to increase or our business otherwise to be harmed.

We could face liability or other expenses for information on or accessible through our online marketplace.

        A significant portion of the information available through our online marketplace, including job postings, caregiver profiles and photographs, is submitted by families, caregivers and third parties. We also allow care-related businesses and other third parties to advertise their products and services on our websites and include links to third-party websites. We could be exposed to liability with respect to this information. Members could assert that information concerning them on our website contains errors or omissions and/or seek damages from us for losses incurred if they rely upon incorrect information provided by our members, care-related businesses or others. We could also be subject to claims that the persons posting information on our websites do not have the right to post such information or are infringing the rights of third parties, such as copyrights in photographs and privacy and publicity rights. Among other things, we might be subject to claims that by directly or indirectly providing links to websites operated by third parties, we are liable for wrongful actions by the third parties operating those websites. These claims also may be brought under foreign laws that often do not provide the same protections for online services companies as in the United States. We could incur significant costs in investigating and defending against these claims even if they do not result in liability to us.

        We also allow families to submit reviews of caregivers. Our terms of use prohibit members from providing inaccurate, misleading, defamatory or false information to us or to any other user of our website and that all opinions expressed must be genuinely held. However, we do not have a regular practice of verifying the accuracy of all member content. There is a risk that a review or other content posted by a member may be considered defamatory or otherwise offensive, objectionable or illegal under applicable law. Therefore, there is a risk that publication on our website of our ratings and reviews may result in a suit against us for defamation, civil rights infringement, negligence, copyright or trademark infringement, invasion of privacy, personal injury, discrimination, or other legal claims. Even if these claims do not result in liability to us, they may result in costly and time-consuming litigation and/or injury to our reputation.

If we are unable to protect our intellectual property rights, our competitive position could be harmed or we could be required to incur significant expenses to enforce our rights.

        We rely on a combination of intellectual property rights, including trade secrets, copyrights and trademarks, as well as contractual restrictions, to safeguard our intellectual property. We do not have any patents or pending patent applications. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy our digital content, aspects of our solutions for members, our technology, software, branding and functionality, or obtain and use information that we consider proprietary. Moreover, policing our proprietary rights is difficult and may not always be effective. As we expand internationally, we may need to enforce our rights under the laws of countries that do not protect proprietary rights to as great an extent as do the laws of the United States.

        Our digital content is not protected by any registered copyrights or other registered intellectual property. Rather, our digital content is protected by statutory and common law rights, user agreements that limit access to and use of our data and by technological measures. Compliance with use restrictions is difficult to monitor, and our proprietary rights in our digital content databases may be more difficult to enforce than other forms of intellectual property rights.

        As of December 31, 2013, we had three registered trademarks in the United States, including "Care.com", which is registered on the supplemental register, four registered trademarks in the EU and one registered trademark in each of Germany and Canada. Some of our trade names may not be eligible to receive trademark protection. Trademark protection may also not be available, or sought by us, in every country in which our service may become available. Competitors may adopt service names similar to ours, or purchase our trademarks and confusingly similar terms as keywords in Internet search engine advertising programs, thereby impeding our ability to build brand identity and possibly confusing consumers and caregivers.

        We currently hold the "Care.com", "Betreut.de", and "Breedlove.com" Internet domain names and various other related domain names. Domain names generally are regulated by Internet regulatory bodies. If we lose the ability to use a domain name in the United States or any other country, we would be forced to incur significant additional expense to market our solutions, including the development of a new brand and the creation of new promotional materials, which could substantially harm our business and operating results. The regulation of domain names in the United States and in foreign countries is subject to change. Regulatory bodies could establish additional top-level domains, appoint additional domain name registrars or modify the requirements for holding domain names. As a result, we may not be able to acquire or maintain the domain names that utilize the "Care" name or other names we utilize in all of the countries in which we currently intend to conduct business.

        In order to protect our trade secrets and other confidential information, we rely in part on confidentiality agreements with our personnel, consultants and third parties with whom we have relationships. These agreements may not effectively prevent disclosure of trade secrets and other confidential information, and may not provide an adequate remedy in the event of misappropriation of trade secrets or any unauthorized disclosure of trade secrets and other confidential information. In addition, others may independently discover trade secrets and confidential information and, in such cases, we could not assert any trade secret rights against such parties. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our trade secret rights and related confidentiality and nondisclosure provisions, and failure to obtain or maintain trade secret protection, or our competitors being able to obtain our trade secrets or to independently develop technology similar to ours or competing technologies, could adversely affect our competitive business position.

Assertions by third parties of infringement or other violation by us of their intellectual property rights could result in significant costs and substantially harm our business and operating results.

        Internet, technology and social media companies are frequently subject to litigation based on allegations of infringement, misappropriation or other violations of intellectual property rights. Some own large numbers of patents, copyrights, trademarks and trade secrets, which they may use to assert claims against us. We have received in the past and may in the future receive notices asserting that we have infringed, misappropriated or otherwise violated a third party's intellectual property rights, and as we face increasing competition, the possibility of intellectual property rights claims against us grows. We cannot assure you that we are not infringing or violating any third-party intellectual property rights.

        We cannot predict whether assertions of third-party intellectual property rights or any infringement or misappropriation claims arising from such assertions will substantially harm our business and operating results. If we are forced to defend against any infringement or misappropriation claims, whether they are with or without merit, are settled out of court or are determined in our favor, we may be required to expend significant time and financial resources on the defense of such claims. Furthermore, an adverse outcome of a dispute may require us to: pay damages, potentially including treble damages and attorneys' fees, if we are found to have willfully infringed a party's patent or copyright rights; cease making, licensing or using solutions that are alleged to infringe or misappropriate the intellectual property of others; expend additional development resources to redesign our solutions; enter into potentially unfavorable royalty or license agreements in order to obtain the right to use necessary technologies, content or materials; and to indemnify our partners and other third parties. Royalty or licensing agreements, if required or desirable, may be unavailable on terms acceptable to us, or at all, and may require significant royalty payments and other expenditures. Any of these events could seriously harm our business, operating results and financial condition. In addition, any lawsuits regarding intellectual property rights, regardless of their success, could be expensive to resolve and would divert the time and attention of our management and technical personnel.

Our revenue may be negatively affected if we are required to charge sales tax or other transaction taxes on all or a portion of our past and future sales in jurisdictions where we are currently not collecting and reporting tax.

        We currently only charge and collect sales or other transaction taxes in certain of the jurisdictions where our members reside. A successful assertion by any state, local jurisdiction or country in which we do not charge and collect such taxes that we should be collecting sales or other transaction taxes on the sale of our products or services, or the imposition of new laws requiring the collection of sales or other transaction taxes on the sale of our products or services, could result in substantial tax liabilities related to past sales, create increased administrative burdens or costs, reduce demand for our products or services, decrease our ability to compete if competitors lower their fees to offset the tax but we do not or otherwise substantially harm our business and results of operations.

Changes in our provision for income taxes or adverse outcomes resulting from examination of our income tax returns could adversely affect our results.

        Our provision for income taxes is subject to volatility and could be adversely affected by the following:

•

changes in the valuation of our deferred tax assets;



•

foreign or domestic income tax assessments and any related tax interest or penalties;



•

expiration of, or lapses in, the research and development tax credit laws;



•

tax effects of nondeductible compensation;



•

adjustments to the pricing of intercompany transactions and transfers of intellectual property or other assets;

25

Table of Contents

•

changes in accounting principles; or



•

changes in tax laws and regulations, including changes in taxation of the services provided by our foreign subsidiaries.

        Significant judgment is required to determine the recognition and measurement attributes prescribed in the accounting guidance for uncertainty in income taxes. The accounting guidance for uncertainty in income taxes applies to all income tax positions, including the potential recovery of previously paid taxes, that if settled unfavorably could adversely impact our provision for income taxes or additional paid-in capital. In addition, we are subject to the examination of our income tax returns by the U.S. Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. The outcomes from these examinations might have a material and adverse effect on our operating results and financial condition.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

        As of December 31, 2012, we had federal net operating loss carryforwards of $42.8 million and state net operating loss carryforwards of $40.2 million. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income and taxes may be limited. In general, an "ownership change" generally occurs if there is a cumulative change in our ownership by "5-percent shareholders" that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. We may have experienced an ownership change in the past and may experience ownership changes in the future as a result of this issuance or future transactions in our stock, some of which may be outside our control. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards, or other pre-change tax attributes, to offset U.S. federal and state taxable income and taxes may be subject to significant limitations.

Our international operations subject us to potentially adverse tax consequences.

        We generally conduct our international operations through wholly owned subsidiaries and report our taxable income in various jurisdictions worldwide based upon our business operations in those jurisdictions. Our intercompany relationships are subject to transfer pricing regulations administered by taxing authorities in various jurisdictions. The relevant taxing authorities may disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a disagreement were to occur, and our position were not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows and lower overall profitability of our operations.

We may not be able to successfully prevent others, including copycat websites and mobile apps, from misappropriating our content in the future.

        From time to time, third parties have attempted to misappropriate our content through website scraping, search robots or other means. We have deployed several technologies designed to detect and prevent such efforts. However, we may not be able to successfully detect and prevent all such efforts in a timely manner or assure that no misuse of our content occurs.

        In addition, third parties operating "copycat" websites have attempted to imitate our brand or the functionality of our service. When we have become aware of such efforts by other companies, we have employed technological or legal measures in an attempt to halt their operations. However, we may not be able to detect all such efforts in a timely manner, or at all, and even if we could, the technological and legal measures available to us may be insufficient to stop their operations. In some cases, particularly in the case

26

Table of Contents

of companies operating outside of the United States, our available remedies may not be adequate to protect us against the damage to our business caused by such websites or mobile apps. Regardless of whether we can successfully enforce our rights against the operation of these third parties, any measures that we may take could require us to expend significant financial or other resources and have a significantly adverse effect on our brand.

Some of our solutions contain open source software, which may pose particular risks to our proprietary software and solutions.

        We use open source software in our solutions and will use open source software in the future. From time to time, we may face claims from third parties claiming ownership of, or demanding release of, the open source software and/or derivative works that we developed using such software (which could include our proprietary source code), or otherwise seeking to enforce the terms of the applicable open source license. These claims could result in litigation and could require us to purchase a costly license or cease offering the implicated solutions unless and until we can re-engineer them to avoid infringement. This re-engineering process could require significant additional research and development resources. In addition to risks related to license requirements, use of certain open source software can lead to greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or controls on the origin of software. Any of these risks could be difficult to eliminate or manage and, if not addressed, could have a negative effect on our business and operating results.

We are an "emerging growth company," and the reduced disclosure requirements applicable to emerging growth companies may make our common stock less attractive to investors.

        We are an "emerging growth company," as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, and may remain an emerging growth company for up to five years. For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements, reduced disclosure obligations regarding executive compensation and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. In this prospectus, we have not included all of the executive compensation-related information that would be required if we were not an emerging growth company. We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

        In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives and corporate governance practices.

        As a public company, and particularly after we are no longer an emerging growth company, we will incur significant legal, accounting and other expenses that we did not incur as a private company. The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing

27

Table of Contents

requirements of The New York Stock Exchange and other applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and corporate governance practices. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, we expect that these rules and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, which could make it more difficult for us to attract and retain qualified members of our board of directors.

        We are currently evaluating these rules and regulations and cannot predict or estimate the amount of additional costs we may incur or the timing of such costs. These rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

        Pursuant to Section 404, we will be required to furnish a report by our management on our internal control over financial reporting beginning with our second filing of an Annual Report on Form 10-K with the Securities and Exchange Commission after we become a public company. However, while we remain an emerging growth company, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. To achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal control over financial reporting is effective as required by Section 404. If we identify one or more material weaknesses, it could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements.

Risks Related to this Offering and Ownership of Our Common Stock

Our stock price may be volatile, and the value of an investment in our common stock may decline.

        Prior to this offering, there has been no public market for shares of our common stock. An active trading market for our common stock may not develop or be sustained, which could depress the market price of our common stock and could affect your ability to sell your shares. The initial public offering price will be determined through negotiations between us and the representatives of the underwriters and may bear no relationship to the price at which our common stock will trade following the completion of this offering. The trading price of our common stock following this offering is likely to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. In addition to the factors discussed in this "Risk Factors" section and elsewhere in this prospectus, these factors include:

•

our operating performance and the operating performance of similar companies;



•

the overall performance of the equity markets;



•

the number of shares of our common stock publicly owned and available for trading;



•

threatened or actual litigation;

28

Table of Contents

•

changes in laws or regulations relating to our solutions;



•

any major change in our board of directors or management;



•

publication of research reports about us or our industry or changes in recommendations or withdrawal of research coverage by securities analysts;



•

large volumes of sales of shares of our common stock by existing stockholders; and



•

general political and economic conditions.

        In addition, the stock market in general, and the market for technology companies in particular, has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of listed companies. Broad market and industry factors may seriously affect the market price of companies' stock, including ours, regardless of actual operating performance. These fluctuations may be even more pronounced in the trading market for our stock shortly following this offering. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company's securities. This litigation, if instituted against us, could result in very substantial costs, divert our management's attention and resources and harm our business, operating results and financial condition.

Sales of substantial amounts of our common stock in the public markets, or the perception that such sales might occur, could reduce the price that our common stock might otherwise attain.

        Based upon the number of shares outstanding as of September 28, 2013, after the completion of the offering, we will have 29,746,202 outstanding shares of common stock (30,548,702 shares of common stock if the underwriters exercise in full their option to purchase additional shares). The shares of our common stock that we are selling in this offering may be resold immediately in the public market. We and all of our directors and officers and substantially all of our stockholders and option holders have agreed not to offer, sell or agree to sell, directly or indirectly, any shares of our common stock without the permission of the underwriters for a period of 180 days from the date of this prospectus. When the lock-up period expires, we and our locked-up security holders will be able to sell our shares in the public market. In addition, the underwriters may, in their sole discretion, release all or some portion of the shares subject to lock-up agreements prior to expiration of the lock-up period. See "Shares Eligible for Future Sale" elsewhere in this prospectus. Sales of a substantial number of such shares upon expiration (or the perception that such sales may occur), or early release, of the lock-up could cause our share price to fall or make it more difficult for you to sell your common stock at a time and price that you deem appropriate.

If securities or industry analysts publish inaccurate or unfavorable research about our business, cease coverage of our company or make projections that exceed our actual results, our stock price and trading volume could decline.

        The trading market for our common stock will be influenced by the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

        Furthermore, such analysts publish their own projections regarding our actual results. These projections may vary widely from one another and may not accurately predict the results we actually achieve. Our stock price may decline if we fail to meet securities and industry analysts' projections.

Our management will have broad discretion over the use of the proceeds we receive in this offering and might not apply the proceeds in ways that increase the value of your investment.

        Our management generally will have broad discretion to use the net proceeds to us from this offering, and you will be relying on the judgment of our management regarding the application of these proceeds. Our management might not apply the net proceeds from this offering in ways that increase the value of your investment. We expect that we will use the net proceeds of this offering to fund increased advertising to achieve membership growth, development of our products and services and for general corporate purposes, including working capital, selling and marketing activities, general and administrative matters and capital expenditures. We may also use a portion of the net proceeds for the acquisition of businesses and assets that we believe are complementary to our own; however, we do not have any agreements or commitments for any specific acquisitions at this time. We have not otherwise allocated the net proceeds from this offering for any specific purposes. Until we use the net proceeds to us from this offering, we plan to invest them, and these investments may not yield a favorable rate of return. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

Concentration of ownership among our officers, directors, large stockholders and their affiliates may prevent new investors, including purchasers in this offering, from influencing corporate decisions.

        Our officers, directors and their affiliated funds and certain of our pre-IPO stockholders beneficially own or control, directly or indirectly, a majority of the outstanding shares of our common stock, assuming no exercise of the underwriters' option to purchase additional shares. As a result, if some of these persons or entities act together, they will have significant influence over the outcome of matters submitted to our stockholders for approval, including the election of directors and approval of significant corporate transactions, such as a merger or other sale of our company or its assets. This concentration of ownership could limit the ability of other stockholders to influence corporate matters and may have the effect of delaying or preventing an acquisition or cause the market price of our stock to decline. Some of these persons or entities may have interests different from yours. For example, because many of these stockholders purchased their shares at prices substantially below the price at which shares are being sold in this offering and have held their shares for a relatively longer period, they may be more interested in selling the company to an acquiror than other investors or may want us to pursue strategies that are different from the wishes of other investors.

We do not intend to pay dividends for the foreseeable future.

        We never have declared or paid any cash dividends on our capital stock and do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain any future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our board of directors. Accordingly, investors must rely on sales of their shares of our common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

Anti-takeover provisions contained in our certificate of incorporation and by-laws, as well as provisions of Delaware law, could impair a takeover attempt.

        Our certificate of incorporation, by-laws and Delaware law contain provisions that could have the effect of rendering more difficult or discouraging an acquisition deemed undesirable by our board of directors. Our corporate governance documents include provisions:

•

authorizing blank check preferred stock, which could be issued with voting, liquidation, dividend and other rights superior to our common stock;



•

limiting the liability of, and providing indemnification to, our directors and officers;

providing that directors may be removed by stockholders only for cause.

        These provisions, alone or together, could delay hostile takeovers and changes in control of our company or changes in our management.
