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 we serve care-related businesses—such as day care centers, nanny agencies and home care agencies—that 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; perception of our brand; coverage by the media and other publicity; 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; access to capital at acceptable terms; outcomes of governmental investigations or other legal proceedings. 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. 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 29, 2018 , filed on March 7, 2019 . There have been no material changes in our significant accounting policies for the three months ended March 30, 2019 as compared to those described in our Annual Report on Form 10-K for the fiscal year ended December 29, 2018 , with the exception of the adoption of the Financial Accounting Standards Board’s Accounting Standard Update 2016-02, “Leases (Topic 842)” in the first quarter of fiscal 2019. Refer below to “Recently Issued and Adopted Accounting Pronouncements” for further information. The condensed consolidated balance sheet as of December 29, 2018 , 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 2019 or any future period. Principles of Consolidation The accompanying condensed 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. Both fiscal 2019 and 2018 are reported using a 52 week fiscal year. 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. In the second quarter of 2019, we ceased using 36,395 square feet of the Company’s headquarters facility located in Waltham, Massachusetts. We expect to record a right of use asset impairment charge ranging from approximately $2.0 million to $4.0 million in the second quarter of 2019. We will finalize the charge in the second quarter of 2019. In the second quarter of 2019, we entered into a 5 -year lease for an office facility in the San Francisco Bay Area. The lease will commence in the second quarter of 2019, and we will pay an aggregate of approximately $5.3 million over the lease term. Recently Adopted Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Non-employee Share-based Payment Accounting.” This guidance simplifies the accounting for share-based payments to non-employees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. We adopted ASU 2018-07 as of the first day of the third quarter in fiscal 2018. The effect of adoption was immaterial. 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 all of its leases with lease 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. We adopted ASU 2016-02 and its amendments in the first quarter of fiscal 2019 using the modified retrospective approach and with a cumulative effect recorded on the date of adoption of December 31, 2018, the first day of our 2019 reporting year. Prior periods were not restated accordingly. We elected the Practical Expedient Package (ASC 842-10-65-1) permitted under the transition guidance within the new standard, which among other things allowed us to carry forward the historical lease classification. Refer to Note 15 “Leases” for the adoption impact to our condensed consolidated balance sheet. The difference between the operating lease liabilities and operating right of use assets is associated with accrued rent payments under ASC 840 and right of use asset impairments related to restructuring activities completed prior to the adoption date associated with our cease use of certain office space subject to operating leases. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract,” which requires that a customer in a cloud computing arrangement that is a service contract follow the internal-use software guidance in Accounting Standards Codification 350-40 to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on recognizing implementation costs incurred in a cloud computing arrangement that is a service contract with that for implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. ASU 2018-15 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application is permitted. We are currently evaluating the impact of ASU 2018-15 on our consolidated financial statements and whether we will early adopt. In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement,” which amends ASC 820, Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The guidance will be effective for us in the first quarter of fiscal 2020. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. We are currently evaluating the impact of ASU 2018-13 on our consolidated financial statements. In January 2017, the FASB issued 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 will be effective for us in our annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted, and we are currently evaluating whether we will early adopt. ASU 2017-04 must be applied prospectively. We expect that ASU 2017-04 would 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 June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 will be effective for us in our first quarter of fiscal 2020, and earlier adoption is permitted. The modified-retrospective approach is required for adoption. We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The following table presents information about our assets and liabilities measured at fair value on a recurring basis as of March 30, 2019 and December 29, 2018 and indicates the fair value hierarchy of the valuation techniques we utilized to determine such fair value (in thousands): March 30, 2019 December 29, 2018 Fair Value Measurements Using Input Types Fair Value Measurements Using Input Types Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Money market mutual funds $ 18,240 $ — $ — $ 18,240 $ 18,148 $ — $ — $ 18,148 Certificates of deposit 37,082 — — 37,082 37,180 — — 37,180 Total assets $ 55,322 $ — $ — $ 55,322 $ 55,328 $ — $ — $ 55,328 Liabilities: Contingent acquisition consideration $ — $ — $ 917 $ 917 $ — $ — $ 1,964 $ 1,964 Total liabilities $ — $ — $ 917 $ 917 $ — $ — $ 1,964 $ 1,964 The following table sets forth a summary of changes in fair value of our contingent acquisition consideration liability, which represents the recurring measurement that is classified within Level 3 of the fair value hierarchy wherein fair value is estimated using significant unobservable inputs (in thousands): March 30, 2019 Contingent Acquisition Consideration Beginning balance - December 29, 2018 $ 1,964 Change in fair value of contingent consideration 110 Payment of contingent consideration liability (1,157 ) Ending balance - March 30, 2019 $ 917 We recorded our estimates of the fair value of contingent consideration associated with the Town & Country Resources, Inc. and Trusted Lab, Inc. acquisitions based on the evaluation of the likelihood of the achievement of the contractual conditions that would result in the payment of the contingent considerations and weighted probability assumptions of these outcomes. For both acquisitions, the fair value of the liability was estimated using the Monte Carlo simulation with significant inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in ASC 820, Fair Value Measurements and Disclosures. The significant inputs in the Level 3 measurement not supported by market activity included our probability assessments of the achievement of certain financial and operational metrics, appropriately discounted considering the uncertainties associated with the obligation, and calculated in accordance with the terms of the merger agreements. The cash portion of the contingent consideration liabilities have been discounted to reflect the time value of money, and therefore, as the milestone dates approach, the fair value of these liabilities will increase. Changes in fair value are recorded in general and administrative expense in the accompanying consolidated statements of operations. Non-Recurring Fair Value Measurements We re-measure the fair value of certain assets and liabilities upon the occurrence of certain events. Such assets comprise long-lived assets, including property and equipment, right of use asset impairments, intangible assets and goodwill. In the three months ended March 30, 2019 and March 31, 2018 , 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. In the quarter ended September 30, 2017, we ceased use of 25,812 square feet of the Company’s headquarters facility and recorded a restructuring liability, which upon adoption of ASC 842 we reclassified this liability as a reduction of the right-of-use asset associated with the lease. We have updated our estimate in subsequent periods, as discussed in Note 12. These estimates include assumptions for the time period it will take to obtain a subtenant, construction costs, and certain sublease rates. These estimates may vary from the sublease agreements ultimately executed, if at all, and could result in an adjustment to the right of use asset. In the first and third quarters of fiscal 2018 and first quarter of fiscal 2019, we updated our assumptions, as we had signed a sublease agreement for a portion of the ceased use space during the first quarter of fiscal 2018 and updated our estimates for the expected time period it will take to obtain a subtenant for the remainder of the cease use space during both the first and third quarters of fiscal 2018. We discounted the estimated future cash flows to arrive at fair value. This resulted in an additional $0.6 million of charges, of which $0.5 million was incurred in the first quarter of fiscal 2018; $0.1 million was incurred in the third quarter of fiscal 2018 and $0.2 million was incurred in the first quarter of fiscal 2019. The measurement of our restructuring charges and right of use asset impairments using these assumptions is a level 3 measurement.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Revenue Recognition Revenue is recognized when control of the promised service is transferred to the customer, in an amount that reflects the consideration we expect to be entitled to in exchange for the service. For all presentations below sales and usage-based taxes are excluded from revenue. The following table presents our revenue disaggregated by major service lines for the three months ended March 30, 2019 and March 31, 2018 (in thousands): Three Months Ended Three Months Ended March 30, 2019 March 31, 2018 Business-to-Consumer Matching Solutions $ 36,304 $ 33,202 Payment Solutions 8,982 8,432 Business-to-Business Care Work Solutions 5,956 3,955 Recruiting and Marketing Solutions and other 2,094 1,736 Total revenue $ 53,336 $ 47,325 The following table presents our revenue disaggregated by timing of transfer of services for the three months ended March 30, 2019 and March 31, 2018 (in thousands): Three Months Ended Three Months Ended March 30, 2019 March 31, 2018 Over-time 46,267 43,704 Point-in-time 7,069 3,621 Total revenue $ 53,336 $ 47,325 Contract Balances The increase in the deferred revenue balance for the three months ended March 30, 2019 was primary driven by cash payments received for our obligation to perform future services during fiscal 2019 , offset by $14.0 million of revenue recognized that was included in the deferred revenue balance as of December 29, 2018 . We consider on-demand back-up care overages for our Care Work offering to be constrained variable consideration in the transaction price until the constraint is resolved upon usage. The revenue recognized in the three months ended March 30, 2019 related to on-demand back-up care overages for our Care Work offering was immaterial. Transaction Price Allocated to the Remaining Performance Obligations For performance obligations that are part of contracts that have an original expected duration of greater than one year, we expect to recognize $5.0 million , $3.5 million , and $1.1 million of revenue related to our Care Work offering in the remainder of fiscal 2019 , fiscal 2020 and fiscal 2021 , respectively, related to performance obligations that are currently unsatisfied (or partially satisfied) as of March 30, 2019 . This disclosure does not include revenue related to performance obligations that are part of a contract whose original expected duration is one year or less. Our matching solutions offering consists of subscription terms whose duration is one year or less, and the service period for our payment solutions revenue is one year or less. Additionally, most of our business-to-business contracts are for durations of one year or less. Furthermore, this disclosure does not include expected consideration related to performance obligations for which we elect to recognize revenue in the amount we have a right to invoice (e.g., usage-based pricing terms). Contract Costs We capitalize sales commissions for new customer contracts in our business-to-business solutions offerings. Capitalized commission are amortized over the period of expected benefit, which is the customer life and we estimate to be approximately five -years. As of March 30, 2019 , capitalized commissions were $1.5 million . For the three months ended March 30, 2019 and March 31, 2018 , amortized commission expense was $0.1 million and less than $0.1 million , respectively. For renewal commissions with a renewal term of one-year of less, we applied the practical expedient and expense commission when incurred because the amortization period would have been one-year or less. These costs are recorded within sales and marketing expense.

Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions Filios Inc. On January 4, 2019, we purchased all of the outstanding stock of Filios, Inc. (“Figure 8”), a mobile app for parents to organize and manage carpools, pursuant to which we acquired the outstanding shares of Figure 8 for total potential consideration of $12.6 million , consisting of $7.6 million as an up-front payment and four earn-outs of $0.5 million , $1.0 million , $1.0 million and $2.5 million to be earned consecutively over one-year periods for four -years. All of the earn-outs were determined to be compensatory in nature based on required future services and product development milestones required to be achieved by the founders who will continue employment with us. The preliminary purchase price of $7.6 million was allocated to assets and liabilities as follows: $4.5 million of goodwill, $3.1 million in identified intangible assets, consisting proprietary technology in the form of Figure 8’s mobile application, as well as working capital assets and liabilities, which were immaterial. Additionally, we increased our goodwill by $0.8 million to record a deferred tax liability in purchase accounting related to the acquired intangible assets. We continue to gather information in the measurement period related to the acquired intangible assets, accrued liabilities and contingent liabilities of Filios, Inc. as of the acquisition date and our purchase accounting for the acquisition is preliminary. Trusted Labs, Inc. On July 12, 2018, we purchased all of the outstanding stock of Trusted Labs, Inc. (“Trusted”), an on-demand child care provider offering service in the San Francisco Bay Area and New York City, pursuant to which we acquired the outstanding shares of Trusted for total potential consideration of $8.1 million , consisting of an up-front payment of $4.6 million , up to $2.2 million in retention payments, earn-out payments of up to an aggregate of $1.0 million to be earned consecutively over three-quarters following the closing, and payments of $0.3 million to settle liabilities. We estimated the fair value of the contingent consideration at the acquisition date to be $1.0 million and thus included this in the total accounting purchase price of $5.6 million . The preliminary purchase price of $5.6 million was allocated to assets and liabilities as follows: $3.4 million of goodwill, $2.5 million in identified intangible assets, consisting primarily of proprietary software and care-giver relationships, and $0.3 million working capital liabilities, which were immaterial. The goodwill is primarily derived from synergies we expect as a result of the deal. Additionally, a discrete tax benefit of $0.6 million was recorded to account for the valuation allowance release primarily related to the acquired intangible assets which have increased fair market value basis for GAAP purposes but carryover basis for tax purposes, resulting in a deferred tax liability that provided a source of income supporting realization of other deferred tax assets. We continue to gather information in the measurement period related to the accrued liabilities and contingent liabilities of Trusted as of the acquisition date and as that information is gathered we may identify opening balance sheet liabilities that could be material to our financial statements that are required to be recorded within the measurement period. At this time we cannot reliably estimate a range of potential liabilities. Galore, Inc. On May 31, 2018, we entered into an asset purchase agreement with Galore, Inc. (“Galore”), an e-commerce marketplace for parents to discover and purchase activities for their children and a SaaS platform for businesses providing family activities to offer those activities for purchase online, pursuant to which we acquired certain assets of Galore for total consideration of $0.3 million as an up-front payment, and two earn-out payments ranging from $0.3 - $0.5 million in year one and $0.7 - $0.9 million in year 2, based upon certain revenue achievement metrics. Due to ongoing service requirements pertaining to the earn-outs, the amounts are being recognized as compensation expense over the required employment period. The purchase price of $0.3 million was allocated to an identified intangible asset, consisting of proprietary software. Town & Country Resources, Inc. On January 9, 2018, we entered into an asset purchase agreement with Town & Country Resources, Inc. (Town & Country), a premium home staffing agency in the San Francisco Bay Area, pursuant to which we acquired certain assets for total potential consideration of $7.0 million , consisting of $5.0 million as an up-front payment, and two earn-outs up to $1.0 million and $1.0 million each to be earned over consecutive one -year periods. We estimated the fair value of the contingent consideration at the acquisition date to be $1.0 million and thus included this in the total accounting purchase price of $6.0 million . The preliminary purchase price of $6.0 million was allocated to assets and liabilities as follows: $4.8 million of goodwill, $1.2 million in identified intangible assets, consisting primarily of caregiver relationships and Town & Country trade-name, and working capital assets and liabilities, which were immaterial. The goodwill is primarily derived from synergies we expect as a result of the deal. Pro forma information related to the acquisitions in fiscal 2018 and 2019 were not presented as the impact of the acquisitions on our consolidated results of operations is not significant.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Legal matters From time to time we are involved in regulatory, governmental and law enforcement inquiries, investigations and subpoenas, as well as legal proceedings, that arise 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 March 2016, we learned of an investigation by the Marin County, California District Attorney’s Office regarding the clarity and conspicuousness of our automatic renewal disclosures and the mechanism by which we obtain informed consent when members purchase premium subscriptions on our website. In September 2016, we learned of an investigation by the San Francisco County, California District Attorney’s Office regarding the accuracy and clarity of our disclosures about the sex offender registry search available to consumers through our website. In 2017, the District Attorneys’ Offices proposed a joint settlement that would include a payment by us of approximately $4.9 million to resolve both investigations. We are in discussions with the District Attorneys’ Offices regarding the proposed settlement and continue to cooperate with the investigations. We have determined that it is probable that we will incur a loss in connection with these matters and have accrued an amount based on the low end of the range of our reasonable estimate of this loss. In addition, on April 3, 2019, a complaint was filed against the Company and two of our officers, Sheila Lirio Marcelo, our chief executive officer, and Michael Echenberg, our chief financial officer, in the U.S. District Court for the District of Massachusetts. The lawsuit purports to be brought on behalf of a class of purchasers of our stock during the period from March 27, 2015 to April 1, 2019, and alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 thereunder, related to the Company’s disclosures about the screening of certain member information for criminal or other inappropriate inactivity. The complaint seeks compensatory and punitive damages, fees, interest, costs and other appropriate relief. Plaintiffs currently have until June 3, 2019 to petition for Lead Plaintiff status. The parties have agreed to defer Care.com’s response until after a lead plaintiff has been appointed and an amended complaint has been filed. The Company is unable to predict the ultimate outcome of this litigation, and therefore cannot estimate possible losses or ranges of losses, if any. We also are currently involved in other pending regulatory and government inquiries and investigations and legal proceedings in the ordinary course of our business. Although the results of these matters cannot be predicted with certainty, we do not believe they will have a material adverse effect on our business. Regardless of the outcome, legal proceedings can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

In the first quarter of fiscal 2019, we granted 0.3 million PSUs. The number of PSUs that become eligible to vest for each recipient will be determined in the first quarter of 2020 based upon our level of achievement of certain financial targets for fiscal 2019. To the extent any PSUs become eligible to vest, they generally will vest over a two -year period, retroactive to March 2019, as continued services are performed. PSUs granted in 2018 and 2017 are vesting over a two -year and three -year period, respectively, retroactive to the grant date of the applicable award. We are recognizing expense using the graded-vesting method based on our estimate of the number of PSUs that will vest. If there is a change in the estimate of the number of PSUs that are probable of vesting, we will cumulatively adjust compensation expense in the period that the change in estimate is made. RSUs and PSUs are not included in issued and outstanding common stock until the shares are vested and released. The grant-date fair value of an RSU and PSU 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, which is the per share par value of our common stock. The weighted-average grant-date fair value per vested RSU and PSU share and the total fair value of vested shares from RSU and PSU grants was $11.73 and $2.3 million , res pectively, for the three months ended March 30, 2019 . The weighted-average grant-date fair value of vested RSU and PSU shares and total fair value of vested shares from RSU and PSU grants were $9.51 and $2.0 million , respectively, for the three months ended March 31, 2018 . During the three months ended March 31, 2018 , we granted 0.1 million stock options to certain employees and directors with a weighted average exercise price per share of $17.45 . We did not grant any stock options during the three months ended March 30, 2019 . A summary of stock option, RSU and PSU activity for the three months ended March 30, 2019 was as follows (in thousands for shares and intrinsic value): Restricted Stock Units Shares Weighted-Average Remaining Contractual Term (Years) Weighted-Average Exercise Price Aggregate Intrinsic Value Shares Weighted-Average Grant Date Fair Value Outstanding as of December 29, 2018 3,524 5.84 $ 9.13 $ 37,477 2,123 $ 15.40 Granted (1) — $ — 978 $ 20.94 Settled (RSUs and PSUs) — (199 ) $ 11.73 Exercised (169 ) $ 7.53 Canceled and forfeited (13 ) $ 9.64 (305 ) $ 18.76 Outstanding as of March 30, 2019 3,342 5.70 $ 9.21 $ 35,550 2,597 $ 16.91 Vested and exercisable as of March 30, 2019 2,436 4.89 $ 8.15 $ 28,552 N/A N/A ____________________________ (1) For RSUs, includes time-based and performance-based Aggregate intrinsic value represents the difference between the closing stock price of our common stock and the exercise price of outstanding, in-the-money options. Our closing stock price as reported on the New York Stock Exchange as of March 29, 2019 , the final trading day of the three months ended March 30, 2019 , was $19.76 . The total intrinsic value of options exercised and RSUs and PSUs vested was approximately $6.6 million and $6.8 million for the three months ended March 30, 2019 and March 31, 2018 , respectively. The aggregate fair value of the options that vested during the three months ended March 30, 2019 and March 31, 2018 was $0.6 million and $0.7 million , respectively. As of March 30, 2019 , total unrecognized compensation cost related to non-vested stock options and RSUs, including PSUs and market-based RSUs, was approximately $3.9 million and $31.9 million , respectively, which is expected to be recognized over a weighted-average period of 1.8 years and 3.0 years, respectively, to the extent they are probable of vesting. As of March 30, 2019 , we had 3.4 million shares available for grant under the 2014 Plan.

Earnings Per Share [Abstract]
Net (Loss) Income per Share Attributable to Common Stockholders	Net (Loss) Income per Share Attributable to Common Stockholders Basic net (loss) 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 March 30, 2019 and March 31, 2018 , we applied the two-class method to calculate basic and diluted net (loss) 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 (loss) income per common share using net (loss) income 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 our Series A Preferred Stock, including accrued dividends, outstanding during the period, except where the effect of such securities would be anti-dilutive. The calculations of basic and diluted net (loss) income per share and basic and diluted weighted-average shares outstanding for the three months ended March 30, 2019 and March 31, 2018 were as follows (in thousands, except per share data): Three Months Ended March 30, 2019 March 31, 2018 Numerator: Basic: Net (loss) income attributable to common stockholders $ (1,746 ) $ 1,741 Diluted: Net (loss) income attributable to common stockholders $ (1,746 ) $ 1,741 Plus: undistributed earnings allocated to participating securities — 956 Less: undistributed earnings reallocated to participating securities — (936 ) Net (loss) income attributable to common stockholders $ (1,746 ) $ 1,761 Denominator: Weighted-average shares outstanding - basic 32,209 30,551 Dilutive impact from: Options outstanding — 2,044 Restricted stock units — 749 Weighted-average shares outstanding - dilutive 32,209 33,344 Net (loss) income per share attributable to common stockholders (Basic): $ (0.05 ) $ 0.06 Net (loss) income per share attributable to common stockholders (Diluted): $ (0.05 ) $ 0.05 The following equity shares were excluded from the calculation of diluted net income per share attributable to common stockholders because their effect would have been anti-dilutive for the periods presented (in thousands): Three Months Ended March 30, March 31, Stock options 3,342 954 Restricted stock units 2,597 294 Series A Redeemable Convertible Preferred Stock (as converted to common stock) 5,117 4,851 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 (loss) income per share attributable to common stockholders.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We are required to compute income tax expense in each jurisdiction in which it operates. This process requires us to project its current tax liability and estimate its deferred tax assets and liabilities, including net operating loss (NOL) and tax credit carry-forwards. In assessing the ability to realize the net deferred tax assets, we consider whether it is more likely than not that some portion or all of the net deferred tax assets will not be realized. ASC 740 requires a valuation allowance to reduce the deferred tax assets if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. On a periodic basis, we reassess the valuation allowance on its deferred tax assets weighing positive and negative evidence to assess the recoverability of the deferred tax assets. In the first quarter of 2019, we made the decision to implement additional screening on individual caregivers seeking jobs through our U.S. consumer marketplace with improvements to be rolled out by the end of the year. We also made the decision to explore other safety initiatives. These safety enhancements represent significant new investments for us that we expect to have an adverse effect on our profitability in fiscal 2019. The effect will be most pronounced in the United States where, based on our current forecasts, we expect to incur a modest pre-tax loss in fiscal 2019, with a return to profitability in fiscal 2020. Using this information, we updated our assessment and considered the positive and negative evidence. We determined that the positive evidence consisting of our cumulative three-year history of profits and future projections which indicate we will remain in a three-year cumulative income position in fiscal 2019 and future years outweighs the negative evidence consisting of pre-tax losses in fiscal 2015 and prior and the challenges to U.S. profitability in 2019 as a result of the factors noted above. In addition, we considered that our U.S. NOL carryforwards do not begin to expire in a material manner until 2028. Therefore, we concluded that it remains more likely than not our deferred taxes will ultimately be realized. If in future periods our profitability is further materially affected by decisions to make additional investments or incur additional costs, or our revenue growth is affected by the factors noted in Note 1 “Certain Significant Risks and Uncertainties”or other factors, it may result in a need to record valuation allowances and such result would likely be material to our reported results of operations. We recorded an income tax benefit of $1.0 million and $0.7 million for the three months ended March 30, 2019 and March 31, 2018 . The tax benefit recorded for the three months ended March 30, 2019 primarily relates to excess tax benefits recorded from the taxable compensation on share-based awards which are recorded discretely each quarter. The tax benefit recorded for the three months ended March 31, 2018 primarily related to the excess tax benefits from the taxable compensation on share-based awards, partially offset by tax expense pertaining to amortization of goodwill associated with the acquisition of Care.com HomePay for tax purposes, for which there was no corresponding book deduction, and certain state taxes based on operating income that are payable without regard to tax loss carryforwards.

Restructuring Charges and RIght of Use Asset Impairments	Restructuring Charges and Right of Use Asset Impairments During the quarter ended September 30, 2017, we ceased use of 25,812 square feet of our 108,743 square foot headquarters facility in Waltham, Massachusetts. We recorded a lease obligation charge of $3.1 million . The lease obligation charge comprised of restructuring expense, including sublease income and construction costs, net of deferred rent liabilities of $2.6 million . Additionally, we wrote off $0.5 million of leasehold improvements related to the space. These estimates may vary from the sublease agreements ultimately executed, if at all, resulting in an adjustment to the charges. The initial restructuring charge was recorded as restructuring expense in the consolidated statements of operations for the three and nine months ended September 30, 2017. In the first quarter of fiscal 2018, we updated our assumptions, as we had signed a sublease agreement for a portion of the ceased use space and updated our estimates for the expected time period it will take to obtain a subtenant for the remainder of the cease use space. This resulted in an additional $0.5 million of restructuring charges in the first quarter of fiscal 2018. During the three months ended September 29, 2018, we again updated our estimate for the expected time it will take to obtain a subtenant for the remainder of the cease use space, resulting in an additional $0.1 million of restructuring charges in the third quarter of fiscal 2018. Upon adoption of ASC 842, we reclassified the restructuring liability from liabilities to a reduction of the right of use asset associated with the lease. Additionally, during the three months ended March 30, 2019, we again updated our assumptions, as we had signed a sublease agreement for the remaining portion of the ceased use space, resulting in an additional $0.2 million of charges in the first quarter of fiscal 2019.

Leases [Abstract]
Leases	Leases On December 30, 2018, we adopted ASU No. 2016-02 - Leases (ASC 842) using the modified retrospective method. We chose to apply the transition provisions as of the period of adoption. Results for reporting periods beginning on or after December 30, 2018 are presented under ASC 842 while prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under ASC 840. Adoption of the new standard resulted in the recording of $20.8 million of operating lease right of use assets, $4.3 million of short-term operating lease liabilities, and $23.5 million of long-term operating lease liabilities. The difference between the operating lease liabilities and operating right of use assets is associated with existing deferred rent under ASC 840 and existing restructuring liabilities under ASC 420, which we removed from our balance sheet upon the adoption of ASC 842. The following table summarizes the amount by which each financial statement line item was affected in the current reporting period due to the adoption of ASC 842 as compared with the guidance that was in effect before the change (in thousands): December 29, 2018 ASC 842 Adjustment December 30, 2018 Assets Operating lease right of use assets, net — 20,832 20,832 Total assets $ 268,067 $ 20,832 $ 288,899 Liabilities, redeemable convertible preferred stock, and stockholders' equity Accrued expenses and other current liabilities * 20,463 (1,071 ) 19,392 Current operating lease liabilities — 4,268 4,268 Total current liabilities 45,603 3,197 48,800 Other non-current liabilities * 6,806 (5,818 ) 988 Non-current operating lease liabilities — 23,453 23,453 Total liabilities 52,847 20,832 73,679 Stockholders' equity Total stockholders' equity 162,213 — 162,213 Total liabilities, redeemable convertible preferred stock and stockholders' equity $ 268,067 $ 20,832 $ 288,899 * Accrued expense and other current liabilities and other non-current liabilities represents lease restructuring charges and deferred rent reflected as reductions in operating lease right of use assets, net. We consider a lease to be a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. We lease office spaces in various locations throughout the United States and Europe. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. For these lease agreements, we have elected the practical expedient to not separate non-lease and lease components and instead to account for them as a single lease component. Some leases include an option to renew, with renewal terms that can extend the lease term from one to ten years. The exercise of lease renewal options is at our sole discretion. None of these options to renew are recognized as part of our right-to-use asset or lease liability as of March 30, 2019 , as renewal was determined to not be reasonably assured. The depreciable life of assets and leasehold improvements are limited by the expected lease term. One of our leases includes variable lease payment based on an index rate, which is included in the lease liability using the index rate as of the lease commencement date. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Additionally, because we elected the practical expedient to not separate non-lease and lease components and instead account for them as a single lease component, our operating leases costs include variable lease costs associated with common area maintenance, insurance and real estate taxes. We sublease certain real estate to third parties. Our subleases are primarily attributable to our headquarters office space in Waltham, Massachusetts. There are no variable lease payments or options to extend the subleases, nor do they contain any material residual value guarantees or material restrictive covenants. As most of our leases do not provide an implicit rate, we used our incremental borrowing rate based on the information available at the adoption or commencement date, in determining the present value of lease payments. The table below summarizes our lease costs as well as sublease income for the three months ended March 30, 2019 (in thousands): Three Months Ended March 30, Lease Costs Statement of Operations Classification Operating lease costs (1) General and administrative $ 1,079 Variable lease costs - operating leases General and administrative 334 Sublease income General and administrative (162 ) Total lease costs $ 1,251 (1) Operating lease costs include short-term leases, which is immaterial.

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. 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 29, 2018 , filed on March 7, 2019 . There have been no material changes in our significant accounting policies for the three months ended March 30, 2019 as compared to those described in our Annual Report on Form 10-K for the fiscal year ended December 29, 2018 , with the exception of the adoption of the Financial Accounting Standards Board’s Accounting Standard Update 2016-02, “Leases (Topic 842)” in the first quarter of fiscal 2019. Refer below to “Recently Issued and Adopted Accounting Pronouncements” for further information. The condensed consolidated balance sheet as of December 29, 2018 , 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 2019 or any future period.
Principles of Consolidation	Principles of Consolidation The accompanying condensed 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. Both fiscal 2019 and 2018 are reported using a 52 week fiscal year.
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.
Recently Issued and Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2018-07, “Compensation - Stock Compensation (Topic 718): Improvements to Non-employee Share-based Payment Accounting.” This guidance simplifies the accounting for share-based payments to non-employees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The guidance is effective for annual periods beginning after December 15, 2018. Early adoption is permitted. We adopted ASU 2018-07 as of the first day of the third quarter in fiscal 2018. The effect of adoption was immaterial. 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 all of its leases with lease 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. We adopted ASU 2016-02 and its amendments in the first quarter of fiscal 2019 using the modified retrospective approach and with a cumulative effect recorded on the date of adoption of December 31, 2018, the first day of our 2019 reporting year. Prior periods were not restated accordingly. We elected the Practical Expedient Package (ASC 842-10-65-1) permitted under the transition guidance within the new standard, which among other things allowed us to carry forward the historical lease classification. Refer to Note 15 “Leases” for the adoption impact to our condensed consolidated balance sheet. The difference between the operating lease liabilities and operating right of use assets is associated with accrued rent payments under ASC 840 and right of use asset impairments related to restructuring activities completed prior to the adoption date associated with our cease use of certain office space subject to operating leases. Recently Issued Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract,” which requires that a customer in a cloud computing arrangement that is a service contract follow the internal-use software guidance in Accounting Standards Codification 350-40 to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 generally aligns the guidance on recognizing implementation costs incurred in a cloud computing arrangement that is a service contract with that for implementation costs incurred to develop or obtain internal-use software, including hosting arrangements that include an internal-use software license. ASU 2018-15 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application is permitted. We are currently evaluating the impact of ASU 2018-15 on our consolidated financial statements and whether we will early adopt. In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement,” which amends ASC 820, Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The guidance will be effective for us in the first quarter of fiscal 2020. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. We are currently evaluating the impact of ASU 2018-13 on our consolidated financial statements. In January 2017, the FASB issued 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 will be effective for us in our annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted, and we are currently evaluating whether we will early adopt. ASU 2017-04 must be applied prospectively. We expect that ASU 2017-04 would 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 June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 will be effective for us in our first quarter of fiscal 2020, and earlier adoption is permitted. The modified-retrospective approach is required for adoption. We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements.
