Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Care.com, Inc. (the “Company”, “we”, “us”, and “our”), a Delaware corporation, was incorporated on October 27, 2006. We are the world’s largest online marketplace for finding and managing family care. Our consumer matching solutions enable families to connect to caregivers and caregiving services in a reliable and easy way, and our payment solutions enable families to pay caregivers electronically online or via their mobile device and to manage their household payroll and tax matters with Care.com HomePay. In addition, we serve employers by providing access to our platform to employer-sponsored families and care-related businesses—such as day care centers, nanny agencies and home care agencies—who wish to market their services to our care-seeking families and recruit our caregiver members. Certain Significant Risks and Uncertainties We operate in a dynamic industry and, accordingly, our business is affected by a variety of factors. For example, we believe that negative changes in any of the following areas could have a significant negative effect on our future financial position, results of operations or cash flows: rates of revenue growth; member engagement and usage of our existing and new products; protection of our brand; retention of qualified employees and key personnel; management of our growth; scaling and adaptation of existing technology and network infrastructure; competition in our market; performance of acquisitions and investments; protection of our intellectual property; protection of customers’ information and privacy concerns; security measures related to our website; and access to capital at acceptable terms, among other things. Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 , filed on March 9, 2017. There have been no material changes in our significant accounting policies for the three months ended April 1, 2017 as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 , with the exception of the adoption of the Financial Accounting Standards Board’s Accounting Standard Update 2016-09. Refer below to “Recently Issued and Adopted Accounting Pronouncements” for further information. The condensed consolidated balance sheet as of December 31, 2016 , included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP on an annual reporting basis. In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, and are not necessarily indicative of the results of operations to be anticipated for fiscal 2017 or any future period. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries, after elimination of all intercompany balances and transactions. We have prepared the accompanying financial statements in conformity with GAAP. Fiscal Year-End We operate and report using a 52 or 53 week fiscal year ending on the Saturday in December closest and prior to December 31. Accordingly, our fiscal quarters end on the Saturday that falls closest to the last day of the third month of each quarter. Subsequent Events Consideration We consider events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. There were no material recognized subsequent events recorded in the condensed consolidated financial statements as of and for the three months ended April 1, 2017 . Recently Issued and Adopted Accounting Pronouncements As an ‘‘emerging growth company’’ under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, we are electing to not take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to not take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable. In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The guidance is effective for us in our annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted. ASU 2017-04 must be applied prospectively. We expect the adoption of this update will simplify our measurement of goodwill impairment, if any of our reporting units have a zero or negative carrying value, or would fail Step 1 of the impairment test following the date of adoption. In November, 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning and ending balances shown on the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. ASU 2016-18 must be applied retrospectively to all periods presented. We do not anticipate that the adoption of this update will have a material impact on our consolidated statement of cash flows. In August 2016, FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230).” ASU 2016-15 amends ASC 230 to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The updated guidance requires a retrospective transition method to each period presented. We do not anticipate that the adoption of this update will have a material impact on our consolidated statement of cash flows. In March 2016, the FASB issued ASU No. 2016-09, “Compensation- Stock Compensation (Topic 718).” The guidance changes how companies account for certain aspects of share-based payments to employees. Entities will be required to recognize income tax effects of awards in the income statement when the awards vest or are settled. The guidance also allows an employer to repurchase more of an employee's shares than it can today for tax withholding purposes providing for withholding at the employee's maximum rate as opposed to the minimum rate without triggering liability accounting and to make a policy election to account for forfeitures as they occur. We adopted this standard in the first quarter of fiscal 2017 using a modified retrospective approach. We elected to account for forfeitures when they occur, rather than to estimate forfeitures when determining the amount of stock-based compensation costs to be recognized in each period. Refer to Note 9 for our accounting policy elections related to income taxes. The adoption of this standard had no material impact on our financial position, results of operations, or statement of cash flows. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The guidance requires an entity to recognize a right-of-use asset and a lease liability for virtually all of its leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. The guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. The updated guidance requires a modified retrospective adoption. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial position and results of operations. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date of ASU 2014-09 by one year to December 15, 2017 for interim and annual reporting periods beginning after that date. Early adoption is permitted but not before the original effective date of December 15, 2016. Since ASU 2014-09 was issued, several additional ASUs have been issued and incorporated within ASC 606 to clarify various elements of the guidance. As of the date of this filing, our evaluation of the effects of Topic 606 are in process and our assessment is preliminary and subject to change. With respect to our consumer matching business, we do not expect the standard to have a material effect on our revenue recognition. Our Care Work contracts have multiple elements, including subscriptions to our website and services, access to back-up care, and access to other services we offer. We are currently evaluating if the standard will affect how we recognize revenue on any elements of these contracts. We are continuing to assess all potential impacts of the standard, including the impact to the pattern with which we recognize revenue for our revenue streams and the impact to the capitalization of costs of commissions. We anticipate to adopt the ASU using the cumulative effect transition method.

Such assets are comprised of long-lived assets, including property and equipment, intangible assets and goodwill. In the three months ended April 1, 2017 and March 26, 2016 , no significant remeasurements were necessary. Other financial instruments not measured or recorded at fair value in the accompanying condensed consolidated balance sheets principally consist of accounts receivable, accounts payable, and accrued liabilities. The estimated fair values of these instruments approximate their carrying values due to their short-term nature.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations During the third quarter of fiscal 2015 we made the decision to exit the Citrus Lane business through either a sale or wind-down, as it was no longer a strategic priority. In the fourth quarter of fiscal 2015, we made the decision to shut down the business and completed our plans for exiting the business in the fourth quarter of 2016. As such, financial results of Citrus Lane have been presented within income (loss) from discontinued operations, net of tax on the consolidated statements of operations for the three months ended April 1, 2017 and March 26, 2016 . As of April 1, 2017 and December 31, 2016 there were no recorded assets or liabilities of the Citrus Lane business. In February 2016, we entered into a settlement agreement with the previous shareholders of Citrus Lane. The settlement agreement related to our acquisition of Citrus Lane and the merger agreement pursuant to which the acquisition was consummated. Under the terms of the settlement agreement, we paid the previous shareholders of Citrus Lane $15.6 million in contingent consideration payments that were valued at $16.0 million as of December 26, 2015 ( $16.4 million was the undiscounted value at the time of the acquisition) that was otherwise payable to them in the event Citrus Lane achieved certain milestones in 2015 and 2016. In exchange, the former shareholders forfeited the $5.0 million in original cash consideration that was being held in an escrow account, as well as the 0.4 million shares of common stock issued at closing (valued at $2.0 million as of the February 2016 settlement date and $3.9 million as of the original closing date) and 0.1 million shares of common stock which was subject to the achievement of certain milestones in 2015 and 2016 (valued at $0.6 million as of the February 2016 settlement date and $1.1 million as of the original closing date) offered as part of the deal consideration. We retired these shares of common stock as of the third quarter of fiscal 2016. As a result of this settlement, and based on our assessment that there was not a clear and direct link to the original consideration transferred at the acquisition date, we have recognized a gain within income from discontinued operations on the consolidated statements of operations for the three months ended March 26, 2016 of $8.0 million . The following table presents financial results of the Citrus Lane business included in income from discontinued operations, net of tax, for the three months ended March 26, 2016 (in thousands). There were no financial results of the Citrus Lane business included in income from discontinued operations, net of tax, for the three months ended April 1, 2017 .

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Legal matters From time to time we are involved in legal proceedings and other regulatory matters arising in the ordinary course of our business. Each reporting period, we evaluate whether or not a loss contingency related to such matters is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. If a loss is probable and the potential estimate of the loss is a range, we evaluate if there is a point within the range that appears at the time to be a better estimate than any other point in the range, and if so, that amount is accrued. If we conclude that no amount in the range appears to be a better estimate than any other, we accrue the minimum amount in the range. We monitor developments in legal matters that could affect estimates we have previously accrued and update our estimates as appropriate based on subsequent developments. In the first quarter of fiscal 2017, we received a demand for payments totaling approximately $1.5 million relating to a government inquiry which commenced in 2016. The Company determined that it is probable that it will incur a loss in connection with this matter and accrued an amount as of December 31, 2016 based on its reasonable estimate of this loss. The Company has accrued an additional amount as of April 1, 2017, based on its updated estimate of this loss. The total amount accrued was not material to our financial statements for the periods ended April 1, 2017 and December 31, 2016 .

Stockholders’ Equity	Stockholders’ Equity Stock-Based Compensation The following table summarizes stock-based compensation in our accompanying condensed consolidated statements of operations (in thousands): Three Months Ended April 1, 2017 March 26, 2016 Cost of revenue $ 92 $ 75 Selling and marketing 246 185 Research and development 281 230 General and administrative 984 878 Income from discontinued operations — 5 Total stock-based compensation $ 1,603 $ 1,373 Pursuant to our 2014 Incentive Award Plan (the “2014 Plan”), during the three months ended April 1, 2017 , we granted 0.3 million time-based restricted stock units (RSUs) to certain employees and directors, and 0.4 million performance-based RSUs to certain members of management. The number of performance-based RSUs that become eligible to vest for each recipient will be determined in the first quarter of 2018 based upon the Company’s level of achievement of certain financial targets for fiscal 2017. To the extent any performance-based RSUs become eligible to vest, they generally will vest over a three -year period retroactive to March 2017 as continued services are performed. Management is recognizing expense straight-line over the required service period based on its estimate of the number of performance-based RSUs that will vest. If there is a change in the estimate of the number of performance-based RSUs that are probable of vesting, we will cumulatively adjust compensation expense in the period that the change in estimate is made. RSUs are not included in issued and outstanding common stock until the shares are vested and released. The fair value of the RSUs is measured based on the market price of the underlying common stock as of the date of grant, reduced by the purchase price of $0.001 per share. The weighted-average grant-date fair value per vested RSU share and the total fair value of vested shares from RSU grants was $7.07 and $1.1 million , res pectively, for the three months ended April 1, 2017 . During the three months ended March 26, 2016 , we granted 0.6 million time-based RSUs to employees, directors and consultants, and 0.5 million performance-based RSUs were granted to certain members of senior management. Management is recognizing expense straight-line over the required service period based on the number of shares that are eligible to vest in accordance with the financial targets met during fiscal 2016. During the three months ended April 1, 2017 , we granted 0.7 million stock options to certain employees and directors with a weighted average exercise price per share of $11.99 . During the three months ended March 26, 2016 , we granted 1.3 million stock options to certain employees and directors with a weighted average exercise price per share of $6.70 .

Our closing stock price as reported on the New York Stock Exchange as of March 31, 2017 , the final trading day of the three months ended April 1, 2017 , was $12.51 . The total intrinsic value of options exercised and RSUs vested was approximately $2.9 million for the three months ended April 1, 2017 . The aggregate fair value of the options that vested during the three months ended April 1, 2017 was $1.5 million . As of April 1, 2017 , total unrecognized compensation cost related to non-vested stock options and RSUs was approximately $6.6 million and $13.3 million , respectively, which is expected to be recognized over a weighted-average period of 3.1 years and 2.7 years, respectively, to the extent they are probable of vesting. As of April 1, 2017 , we had 3.0 million shares available for grant under the 2014 Plan.

Earnings Per Share [Abstract]
Net Income per Share Attributable to Common Stockholders	et Income per Share Attributable to Common Stockholders Basic net income per share is computed by dividing net income attributable to common shareholders by the weighted-average number of common shares outstanding during the period. For the three months ended April 1, 2017 , we applied the two-class method to calculate basic and diluted net income per share of common stock, as our Series A Redeemable Convertible Preferred Stock (Series A Preferred Stock) is a participating security. The two-class method is an earnings allocated formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. We compute diluted net income per common share using income from continuing operations as the “control number” in determining whether potential common shares are dilutive, after giving consideration to all potentially dilutive common shares, including stock options, unvested restricted stock outstanding during the period and potential issuance of stock upon the conversion of the our Series A Preferred Stock, including accrued dividends, outstanding during the period, except where the effect of such securities would be antidilutive. The calculations of basic and diluted net income per share and basic and dilutive weighted-average shares outstanding for the three months ended April 1, 2017 and March 26, 2016 were as follows (in thousands, except per share data): Three Months Ended April 1, 2017 March 26, 2016 Numerator: Net income attributable to common stockholders $ 192 $ 6,755 Denominator: Weighted-average shares outstanding - basic 29,149 32,229 Dilutive impact from: Options outstanding 1,705 861 Restricted stock units 428 498 Weighted-average shares outstanding - dilutive 31,282 33,588 Net income per share attributable to common stockholders (Basic): Income (loss) from continuing operations attributable to common stockholders $ 0.01 $ (0.03 ) Income from discontinued operations attributable to common stockholders — 0.24 Net income per share attributable to common stockholders $ 0.01 $ 0.21 Net income per share attributable to common stockholders (Diluted): Income (loss) from continuing operations attributable to common stockholders $ 0.01 $ (0.03 ) Income from discontinued operations attributable to common stockholders — 0.23 Net income per share attributable to common stockholders $ 0.01 $ 0.20 The following equity shares were excluded from the calculation of diluted net income per share from continuing operations and discontinued operations because their effect would have been anti-dilutive for the periods presented (in thousands): Three Months Ended April 1, March 26, Stock options 2,962 1,794 Restricted stock units 1,391 1,733 Series A Redeemable Convertible Preferred Stock (as converted to common stock) 4,596 — The Series A Preferred Stock is considered anti-dilutive due to the fact that the two-class method was more dilutive when calculating dilutive net income per share attributable to common stockholders.

Series A Redeemable Convertible Preferred Stock (Series A Preferred Stock) On June 29, 2016 (the “Closing Date”), we announced the entry into an Investment Agreement, dated as of June 29, 2016 with CapitalG LP (“CapitalG”) relating to the issuance and sale to CapitalG of 46.4 thousand shares of our Series A Redeemable Convertible Preferred Stock, par value $0.001 per share (“Series A Preferred Stock”), for an aggregate purchase price of $46.4 million , or $1,000 per share. We incurred issuance costs of $2.1 million . We elected to accrete all issuance costs that were netted against the proceeds upon issuance of the Series A Preferred Stock. The Series A Preferred Stock has the following rights and preferences: Voting The holders of Series A Preferred Stock have full voting rights and powers equal to the rights and powers of holders of shares of Common Stock, with respect to any matters upon which holders of shares of Common Stock have the right to vote. Holders of Series A Preferred Stock are entitled to the number of votes equal to the number of whole shares of Common Stock into which such share of Series A Preferred Stock could be converted at the record date for determination of the stockholders entitled to vote on such matters. Additionally, at any time when at least 50% of the shares of the Series A Preferred Stock purchased from the Company pursuant to the Investment Agreement are outstanding, the Company cannot, without the written consent or affirmative vote of the holders of a majority of the then outstanding shares of preferred stock, (a) amend the Certificate of Incorporation in a manner that adversely affects the preferences or rights of the preferred stock; (b) authorize or issue capital stock unless it ranks equal to or junior to the preferred stock, or increase the authorized number of shares of preferred stock; or (c) reclassify or amend any existing security of the Company that is equal to or junior to the preferred stock to render such security senior to the Series A Preferred Stock. Dividends The Series A Preferred Stock ranks senior to the shares of our Common Stock with respect to dividend rights and rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company. Holders of the Series A Preferred Stock are entitled to a cumulative dividend at a rate of 5.50% per annum during the period from the Closing Date to the seventh anniversary of the Closing Date, payable semi-annually in arrears. Dividends are paid in additional Liquidation Preference per share of Series A Preferred Stock. Liquidation Preference The Series A Preferred Stock has a Liquidation Preference of $1,000 per share plus all Accrued and Unpaid Dividends. The Series A Preferred Stock ranks senior to the Common Stock with respect to rights upon liquidation, winding-up and dissolution. Conversion The Series A Preferred Stock is convertible at the option of the holders at any time into shares of Common Stock at an initial Conversion Price of $10.50 per share, which rate is subject to adjustment upon the occurrence of certain events. At any time after the seventh anniversary of the Closing Date, and if between the fifth anniversary and the seventh anniversary of the Closing Date, the consolidated closing price of the Common Stock equals or exceeds 150% of the then prevailing Conversion Price for at least 20 trading days in any period of 30 consecutive trading days, including the last trading day of such 30-day period, then following such time, all or some of the Series A Preferred Stock may be converted, at our election, into the relevant number of shares of Common Stock. Redemption At our option, at any time after the seventh anniversary of the Closing Date, all of the Series A Preferred Stock may be redeemed by us at the then current Liquidation Preference plus Accrued and Unpaid Dividends after giving the holders of Series A Preferred Stock the ability to convert their shares into Common Stock. At any point after the seventh anniversary of the Closing Date, each holder of the Series A Preferred Stock may cause us to redeem all of such holder’s Series A Preferred Stock at the then current Liquidation Preference plus Accrued and Unpaid Dividends. We elected to accrete all issuance costs that were netted against the proceeds upon issuance of the Series A Preferred Stock. We will accrete the carrying value of the Series A Preferred Stock to the redemption value through June 29, 2023, which is the seventh anniversary of the Closing Date, at a rate of 5.50% per annum, which represents the cumulative dividends owed on the Series A Preferred Stock, using the interest rate method. Change in Control Events Upon certain change of control events involving the Company, holders of Series A Preferred Stock can elect to either (1) convert the Series A Preferred Stock to Common Stock at the then current Conversion Price or (2) require us to redeem the Series A Preferred Stock for 150% of the then current Liquidation Preference plus Accrued and Unpaid Dividends, provided that in the case of a change of control event in which the Common Stock is converted into or canceled for cash or publicly traded securities, such conversion or redemption will be mandatory, with the selection deemed to be in favor of the alternative that would result in holders of Series A Preferred Stock receiving the greatest consideration. Board of Directors Seat Pursuant to the Investment Agreement and the Certificate of Designations, we have agreed that, so long as CapitalG or its affiliates beneficially own at least 50% of the shares of Series A Preferred Stock purchased in the transaction, the holders of Series A Preferred Stock shall have the right to elect one member of the board of directors, and CapitalG has the right to designate the nominee for such position. Standstill Restrictions Pursuant to the Investment Agreement, CapitalG is subject to certain standstill restrictions, including, among other things, that CapitalG is restricted from acquiring additional securities of the Company until the later of (a) the 18 month anniversary of the Closing Date and (b) the date that no CapitalG designee serves on the Company’s board of directors. Subject to certain customary exceptions, CapitalG is restricted from transferring the Series A Preferred Stock or, if converted, any shares of Common Stock underlying the Series A Preferred Stock until the earlier of the 18 month anniversary of the Closing Date or immediately prior to a change of control of the Company.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recorded income tax expense of $0.2 million and $0.0 million for the three months ended April 1, 2017 and March 26, 2016 , respectively. The tax provision recorded for the three months ended April 1, 2017 primarily related to the amortization of goodwill associated with the acquisition of Care.com HomePay for tax purposes, for which there is no corresponding book deduction, and certain state taxes based on operating income that are payable without regard to tax loss carryforwards. Prior to January 1, 2017, we recognized the excess tax benefits of stock-based compensation expense as additional paid-in capital (“APIC”), and tax deficiencies of stock-based compensation expense in the income tax provision or as APIC to the extent that there were sufficient recognized excess tax benefits previously recognized. As a result of the prior guidance that excess tax benefits reduce taxes payable prior to being recognized as an increase in paid in capital, we had not recognized certain deferred tax assets (all tax attributes such as loss or credit carryforwards) that could be attributed to tax deductions related to equity compensation in excess of compensation recognized for financial reporting. As of January 1, 2017, we had generated federal and state net operating loss carryforwards due to excess tax benefits of $2.2 million and $1.9 million , respectively. Effective as of January 1, 2017, we adopted a change in accounting policy in accordance with ASU 2016-09 to account for excess tax benefits and tax deficiencies as income tax expense or benefit, treated as discrete items in the reporting period in which they occur, and to recognize previously unrecognized deferred tax assets that arose directly from (or the use of which was postponed by) tax deductions related to equity compensation in excess of compensation recognized for financial reporting. No prior periods were re-cast as a result of this change in accounting policy, as we had previously maintained a valuation allowance against our deferred tax assets that could be attributed to equity compensation in excess of compensation recognized for financial reporting .

Restructuring and Related Activities [Abstract]
Restructuring Charges	Restructuring Charges On April 14, 2016, we entered into a sublease agreement to lease approximately 10,362 square feet of our 108,743 square foot headquarters facility located in Waltham, Massachusetts. During the quarter ended June 25, 2016, we recorded a $0.5 million sublease loss liability and related expenses of $0.2 million for the expected loss on the sublease, in accordance with ASC 840-20, Leases , because the monthly payments we expect to receive under the sublease are less than the amounts that we will owe the lessor for the sublease space. The sublease term is less than the remaining term under the original lease, and thus we do not believe we have met a cease use date as we may re-enter the space following the sublease. The fair value of the liability was determined using the estimated future net cash flows, consisting of the minimum lease payments to the lessor for the sublease space and payments we will receive under the sublease. The sublease loss was recorded as part of restructuring expense in the consolidated statement of operations. The following table presents the change in restructuring liability from December 31, 2016 to April 1, 2017 (in thousands): April 1, 2017 Restructuring Liability Balance as of December 31, 2016 $ 356 Restructuring charges — Payments — Changes in estimate — Accretion of sublease liability (25 ) Balance as of April 1, 2017 $ 331

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 , filed on March 9, 2017. There have been no material changes in our significant accounting policies for the three months ended April 1, 2017 as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 , with the exception of the adoption of the Financial Accounting Standards Board’s Accounting Standard Update 2016-09. Refer below to “Recently Issued and Adopted Accounting Pronouncements” for further information. The condensed consolidated balance sheet as of December 31, 2016 , included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP on an annual reporting basis. In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, and are not necessarily indicative of the results of operations to be anticipated for fiscal 2017 or any future period.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries, after elimination of all intercompany balances and transactions. We have prepared the accompanying financial statements in conformity with GAAP.
Fiscal Year-End	Fiscal Year-End We operate and report using a 52 or 53 week fiscal year ending on the Saturday in December closest and prior to December 31. Accordingly, our fiscal quarters end on the Saturday that falls closest to the last day of the third month of each quarter.
Subsequent Events Consideration	Subsequent Events Consideration We consider events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. There were no material recognized subsequent events recorded in the condensed consolidated financial statements as of and for the three months ended April 1, 2017 .
Recently Issued and Adopted Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements As an ‘‘emerging growth company’’ under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, we are electing to not take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision to not take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable. In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. The guidance is effective for us in our annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted. ASU 2017-04 must be applied prospectively. We expect the adoption of this update will simplify our measurement of goodwill impairment, if any of our reporting units have a zero or negative carrying value, or would fail Step 1 of the impairment test following the date of adoption. In November, 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash.” ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning and ending balances shown on the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. ASU 2016-18 must be applied retrospectively to all periods presented. We do not anticipate that the adoption of this update will have a material impact on our consolidated statement of cash flows. In August 2016, FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230).” ASU 2016-15 amends ASC 230 to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The updated guidance requires a retrospective transition method to each period presented. We do not anticipate that the adoption of this update will have a material impact on our consolidated statement of cash flows. In March 2016, the FASB issued ASU No. 2016-09, “Compensation- Stock Compensation (Topic 718).” The guidance changes how companies account for certain aspects of share-based payments to employees. Entities will be required to recognize income tax effects of awards in the income statement when the awards vest or are settled. The guidance also allows an employer to repurchase more of an employee's shares than it can today for tax withholding purposes providing for withholding at the employee's maximum rate as opposed to the minimum rate without triggering liability accounting and to make a policy election to account for forfeitures as they occur. We adopted this standard in the first quarter of fiscal 2017 using a modified retrospective approach. We elected to account for forfeitures when they occur, rather than to estimate forfeitures when determining the amount of stock-based compensation costs to be recognized in each period. Refer to Note 9 for our accounting policy elections related to income taxes. The adoption of this standard had no material impact on our financial position, results of operations, or statement of cash flows. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The guidance requires an entity to recognize a right-of-use asset and a lease liability for virtually all of its leases with terms of more than 12 months. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. The amendments also require certain quantitative and qualitative disclosures about leasing arrangements. The guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. The updated guidance requires a modified retrospective adoption. We are currently evaluating the impact of the adoption of ASU 2016-02 on our consolidated financial position and results of operations. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date of ASU 2014-09 by one year to December 15, 2017 for interim and annual reporting periods beginning after that date. Early adoption is permitted but not before the original effective date of December 15, 2016. Since ASU 2014-09 was issued, several additional ASUs have been issued and incorporated within ASC 606 to clarify various elements of the guidance. As of the date of this filing, our evaluation of the effects of Topic 606 are in process and our assessment is preliminary and subject to change. With respect to our consumer matching business, we do not expect the standard to have a material effect on our revenue recognition. Our Care Work contracts have multiple elements, including subscriptions to our website and services, access to back-up care, and access to other services we offer. We are currently evaluating if the standard will affect how we recognize revenue on any elements of these contracts. We are continuing to assess all potential impacts of the standard, including the impact to the pattern with which we recognize revenue for our revenue streams and the impact to the capitalization of costs of commissions. We anticipate to adopt the ASU using the cumulative effect transition method.
