Organization Consolidation And Presentation Of Financial Statements [Abstract]
Company Overview and Basis of Presentation	1. Company Overview and Basis of Presentation Business SVMK Inc. (the “Company”) is a leading global provider of software solutions for customer experience, market research and survey feedback. The Company was incorporated in 2011 as a Delaware corporation and is the successor to operations originally begun in 1999. The Company’s headquarters are located in the United States and its international operations are primarily based in Ireland, Canada and the Netherlands. Principles of Consolidation and Basis of Presentation The accompanying interim condensed consolidated balance sheet as of June 30, 2020, the statements of operations, comprehensive loss and stockholders’ equity for the three and six months ended June 30, 2020 and 2019, and cash flows for the six months ended June 30, 2020 and 2019 are unaudited. Such condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. These condensed consolidated financial statements include the results of operations of the Company and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated . These condensed consolidated financial statements do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. In management’s opinion, the condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of June 30, 2020, the results of operations for the three and six months ended June 30, 2020 and 2019, and cash flows for the six months ended June 30, 2020 and 2019. The results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual periods. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Form-10K filed with the SEC on February 27, 2020. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenue and expenses during the reporting periods covered by the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates due to a variety of factors, including the unforeseen effects of the COVID-19 pandemic on the Company’s business and financial results. Due to the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstances that would require an update to its estimates, judgments or assumptions or a revision to the carrying value of its assets or liabilities as of the date of issuance of its financial statements. These estimates, judgments and assumptions may change in the future, as new events occur or additional information is obtained. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable. The Company’s most significant estimates and judgments involve valuation of deferred income tax assets, valuation of acquired goodwill and intangibles from acquisitions, tax contingencies, legal contingencies and incremental borrowing rate for operating leases. Segment Information The Company operates as a single Related Party Transactions Certain members of the Company’s Board of Directors (“Board”) serve as board members, are executive officers of and/or (in some cases) are investors in companies that are customers and/or vendors of the Company. The Company incurred related party expenses of $1.0 million and $2.0 million for the three and six months ended June 30, 2020, respectively, and $0.5 million and $0.8 million during the three and six months ended June 30, 2019, respectively.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies There have been no material changes in our significant accounting policies as described in our Annual Report on Form 10-K for the year ended December 31, 2019. On January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses Revenue Recognition and Deferred Revenue The Company generates substantially all of its revenue from the sale of subscriptions to its survey software products including subscriptions to its purpose-built solutions. The revenue the Company generates from one purpose-built solution that is delivered and recognized at a point in time is not significant. The Company recognized into revenue $65.1 million and $105.5 million during the three and six months ended June 30, 2020, respectively, and $36.9 million and $68.3 million during the three and six months ended June 30, 2019, respectively, that was included in the deferred revenue balances at the beginning of each respective period. As of June 30, 2020, future estimated revenue related to non-cancelable performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period was $178.1 million. The substantial majority of the unsatisfied performance obligations will be satisfied over the next twelve months. Accounts Receivable Accounts receivable are presented at amortized cost net of amounts not expected to be collected. Accounts receivable are customer obligations that arise due to the time taken to settle transactions through direct customer payments. The Company bills in advance for monthly contracts and generally bills annually in advance for contracts with terms of one year or longer when it has an unconditional contractual right to consideration. The Company also recognizes an immaterial amount of contract assets, or unbilled receivables, primarily relating to rights to consideration for services completed but not billed at the reporting date. Unbilled receivables are classified as receivables when the Company has the right to invoice the customer. The Company records an allowance for credit losses based upon its assessment of various factors including the Company’s a) historical experience (including historical bad debt expense trends), the age of a customers’ accounts receivable balance, and a customers’ credit quality, b) expected losses over the remaining estimated contractual life of the receivable and c) other reasonable and supportable factors pertaining to a customers’ ability to pay (including consideration of current economic conditions). Amounts deemed uncollectible and expected credit losses are recorded to the allowance for doubtful accounts with an offsetting charge in the condensed consolidated statements of operations. The Company evaluated its allowance for credit losses using its consolidated gross accounts receivable balance as a single portfolio segment. Bad debt expense recognized in the condensed consolidated statements of operations was $0.4 million and $0.8 million during the three and six months ended June 30, 2020, respectively, and $0.1 million and $0.2 million during the three and six months ended June 30, 2019, respectively. Other Non-Operating (Income) Expense Other non-operating (income) expense, net consists primarily of interest income, net foreign currency exchange (gains) losses, gain on sale of private company investments, net realized gains and losses related to investments, and other. The components of other non-operating (income) expense recognized in the condensed consolidated financial statements is as follows: Three Months Ended June 30, Six Months Ended June 30, (in thousands) 2020 2019 2020 2019 Interest Income $ (72 ) $ (776 ) $ (479 ) $ (1,714 ) Foreign currency (gains) losses, net 166 305 344 323 Gain on sale of a private company investment — — (1,001 ) (1,001 ) Other (income) expense, net 8 (104 ) 2 (162 ) Other non-operating (income) expense, net $ 102 $ (575 ) $ (1,134 ) $ (2,554 ) In January 2017, the Company sold a private company investment that was accounted for using the cost method of accounting. The Company recognized an initial gain upon sale and was additionally entitled to receive contingent consideration to be received over three years following the close of the transaction. In each of the six months ended June 30, 2020 and 2019, the Company received cash of $1.0 million, representing its share of the respective second and final installments of the earn-out payment, each of which was recognized as a gain on sale of a private company investment. Accounting Pronouncements Recently Adopted Credit Losses : In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses ("ASU 2016-13"). ASU 2016-13 replaces the incurred loss impairment methodology in the current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade receivables and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. ASU 2016-13 is effective for public companies with fiscal years beginning after December 15, 2019, with early adoption permitted. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. The Company adopted ASU 2016-13, including applicable amendments in other ASUs issued subsequent to ASU 2016-13, with no material impact upon adoption. Accounting Pronouncements Not Yet Adopted Income Taxes : In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. ASU 2019-12 also improves consistent application and simplifies other areas of Topic 740 by clarifying and amending existing guidance. Early adoption is permitted, provided that the Company reflects any adjustments as of the beginning of the annual period that includes the interim period for which such early adoption occurs. Additionally, the Company must adopt all the amendments in the same period if early adoption is elected. ASU 2019-12 is effective for public companies with fiscal years beginning after December 15, 2020, unless early adopted. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements. Reference Rate Reform : In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 is intended to provide temporary optional expedients and exceptions to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the impact this guidance may have on its condensed consolidated financial statements and related disclosures.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements Assets and liabilities recorded at fair value in the condensed consolidated financial statements are categorized based on the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels which directly relate to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities are as follows: Level 1 – Observable inputs, such as quoted prices in active markets for identical assets or liabilities. Level 2 – Observable inputs, other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying amounts of the Company’s financial instruments, which generally include cash equivalents, accounts receivable and accounts payable, approximate their fair values due to their short maturities. Based on borrowing rates currently available to the Company for debt with similar terms and consideration of default and credit risk, the fair value of the Company’s debt was approximately $209.7 million as of June 30, 2020 and was approximate to its carrying value as of December 31, 2019. As of June 30, 2020 and December 31, 2019, respectively, the Company did not have any financial instruments accounted for pursuant to ASC 820.

The decrease in the Company’s income tax benefit for the three and six months ended June 30, 2020, relative to the respective prior period, was primarily due to the Company’s expanding international footprint and the partial release of the valuation allowance in the second quarter of 2019 as a result of the Usabilla acquisition. The Company regularly evaluates the realizability of its net deferred tax assets based on all available evidence, both positive and negative. The realization of net deferred tax assets is dependent on several factors, including the likelihood and amount, if any, of future taxable income in relevant jurisdictions during periods in which those temporary differences become deductible. As of June 30, 2020, the Company continues to maintain a valuation allowance on certain deferred tax assets in the United States and Ireland that are not realizable on a more likely than not basis. The Company believes that it has provided adequate reserves for its income tax uncertainties in all open tax years. As the outcome of the audits cannot be predicted with certainty, if any issues addressed in the Company's tax audits are resolved in a manner inconsistent with management's expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. There were no material changes in gross unrecognized tax benefits during each of the three and six months ended June 30, 2020 and 2019. On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion invalidating the regulations relating to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. A final decision was issued by the Tax Court in December 2015. The Internal Revenue Service appealed the Tax Court decision in June 2016. On July 24, 2018, the Ninth Circuit Federal Court issued a decision that was subsequently withdrawn and a reconstituted panel conferred on the appeal. On June 7, 2019, the Ninth Circuit Federal Court panel upheld the cost-sharing regulations. On July 22, 2019, Intel Corporation, which acquired Altera Corp., filed a request for rehearing of the case by the entire Ninth Circuit Federal Court, which was denied on November 11, 2019. On February 10, 2020, Intel Corporation filed a petition with the United States Supreme Court which was denied on June 22, 2020, therefore validating the Ninth Circuit Federal Court decision to uphold the cost sharing regulations. Upon resolution of all appeals, the Company recorded a cumulative reduction to its deferred tax assets related to non-operating losses of $9.0 million, offset by a corresponding valuation allowance release. In addition, the Company has commenced including stock-based compensation in its cost share allocation. Due to the full valuation allowance the Company has against its deferred tax assets in the United States and Ireland, the change does not have a material impact to its effective tax rate and income tax expense.

Geographical Information	12. Geographical Information Revenue by geography is generally based on the billing address of the customer. For purposes of its geographic revenue disclosure, the Company defines a customer as an organization. An organization may consist of an individual paying user, multiple paying users within an organization or the organization itself. The following table sets forth the percentage of revenue by geographic area: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 United States 65 % 64 % 65 % 65 % Rest of world 35 % 36 % 35 % 35 % No other country outside of the United States comprised 10% or greater of the Company’s revenue for the three months ended June 30, 2020 and 2019.

Earnings Per Share [Abstract]
Net Loss Per Share	13. Net Loss Per Share Basic earnings per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net loss for the period by the weighted-average number of common shares outstanding during the period which includes potential dilutive common shares assuming the dilutive effect of outstanding stock options, restricted stock units (including those that are performance-based) and restricted stock awards calculated using the treasury stock method. The following table sets forth the computation of basic and diluted earnings per share: Three Months Ended June 30, Six Months Ended June 30, (in thousands, except per share amounts) 2020 2019 2020 2019 Numerator: Net loss $ (22,924 ) $ (18,478 ) $ (47,174 ) $ (36,255 ) Denominator: Weighted-average shares outstanding - basic and diluted 138,777 131,099 137,844 128,943 Net loss per common share - basic and diluted: $ (0.17 ) $ (0.14 ) $ (0.34 ) $ (0.28 ) The Company was in a loss position for the periods presented. Accordingly, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been anti-dilutive. Prior to application of the treasury stock method, share equivalents (comprising restricted stock units (including those that are performance-based), stock options, restricted stock awards, and shares issuable under the ESPP) excluded from the calculations of diluted net loss per share were 25.4 million during the three and six months ended June 30, 2020, and 25.2 million during the three and six months ended June 30, 2019.

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying interim condensed consolidated balance sheet as of June 30, 2020, the statements of operations, comprehensive loss and stockholders’ equity for the three and six months ended June 30, 2020 and 2019, and cash flows for the six months ended June 30, 2020 and 2019 are unaudited. Such condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. These condensed consolidated financial statements include the results of operations of the Company and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated . These condensed consolidated financial statements do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. In management’s opinion, the condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of June 30, 2020, the results of operations for the three and six months ended June 30, 2020 and 2019, and cash flows for the six months ended June 30, 2020 and 2019. The results of operations for the three and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual periods. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Form-10K filed with the SEC on February 27, 2020.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenue and expenses during the reporting periods covered by the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates due to a variety of factors, including the unforeseen effects of the COVID-19 pandemic on the Company’s business and financial results. Due to the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstances that would require an update to its estimates, judgments or assumptions or a revision to the carrying value of its assets or liabilities as of the date of issuance of its financial statements. These estimates, judgments and assumptions may change in the future, as new events occur or additional information is obtained. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable. The Company’s most significant estimates and judgments involve valuation of deferred income tax assets, valuation of acquired goodwill and intangibles from acquisitions, tax contingencies, legal contingencies and incremental borrowing rate for operating leases.

Related Party Transactions	Related Party Transactions Certain members of the Company’s Board of Directors (“Board”) serve as board members, are executive officers of and/or (in some cases) are investors in companies that are customers and/or vendors of the Company. The Company incurred related party expenses of $1.0 million and $2.0 million for the three and six months ended June 30, 2020, respectively, and $0.5 million and $0.8 million during the three and six months ended June 30, 2019, respectively.
Revenue Recognition and Deferred Revenue	Revenue Recognition and Deferred Revenue The Company generates substantially all of its revenue from the sale of subscriptions to its survey software products including subscriptions to its purpose-built solutions. The revenue the Company generates from one purpose-built solution that is delivered and recognized at a point in time is not significant. The Company recognized into revenue $65.1 million and $105.5 million during the three and six months ended June 30, 2020, respectively, and $36.9 million and $68.3 million during the three and six months ended June 30, 2019, respectively, that was included in the deferred revenue balances at the beginning of each respective period. As of June 30, 2020, future estimated revenue related to non-cancelable performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period was $178.1 million. The substantial majority of the unsatisfied performance obligations will be satisfied over the next twelve months.
Accounts Receivable	Accounts Receivable Accounts receivable are presented at amortized cost net of amounts not expected to be collected. Accounts receivable are customer obligations that arise due to the time taken to settle transactions through direct customer payments. The Company bills in advance for monthly contracts and generally bills annually in advance for contracts with terms of one year or longer when it has an unconditional contractual right to consideration. The Company also recognizes an immaterial amount of contract assets, or unbilled receivables, primarily relating to rights to consideration for services completed but not billed at the reporting date. Unbilled receivables are classified as receivables when the Company has the right to invoice the customer. The Company records an allowance for credit losses based upon its assessment of various factors including the Company’s a) historical experience (including historical bad debt expense trends), the age of a customers’ accounts receivable balance, and a customers’ credit quality, b) expected losses over the remaining estimated contractual life of the receivable and c) other reasonable and supportable factors pertaining to a customers’ ability to pay (including consideration of current economic conditions). Amounts deemed uncollectible and expected credit losses are recorded to the allowance for doubtful accounts with an offsetting charge in the condensed consolidated statements of operations. The Company evaluated its allowance for credit losses using its consolidated gross accounts receivable balance as a single portfolio segment. Bad debt expense recognized in the condensed consolidated statements of operations was $0.4 million and $0.8 million during the three and six months ended June 30, 2020, respectively, and $0.1 million and $0.2 million during the three and six months ended June 30, 2019, respectively.
Other Non-Operating (Income) Expense	Other Non-Operating (Income) Expense Other non-operating (income) expense, net consists primarily of interest income, net foreign currency exchange (gains) losses, gain on sale of private company investments, net realized gains and losses related to investments, and other. The components of other non-operating (income) expense recognized in the condensed consolidated financial statements is as follows: Three Months Ended June 30, Six Months Ended June 30, (in thousands) 2020 2019 2020 2019 Interest Income $ (72 ) $ (776 ) $ (479 ) $ (1,714 ) Foreign currency (gains) losses, net 166 305 344 323 Gain on sale of a private company investment — — (1,001 ) (1,001 ) Other (income) expense, net 8 (104 ) 2 (162 ) Other non-operating (income) expense, net $ 102 $ (575 ) $ (1,134 ) $ (2,554 ) In January 2017, the Company sold a private company investment that was accounted for using the cost method of accounting. The Company recognized an initial gain upon sale and was additionally entitled to receive contingent consideration to be received over three years following the close of the transaction. In each of the six months ended June 30, 2020 and 2019, the Company received cash of $1.0 million, representing its share of the respective second and final installments of the earn-out payment, each of which was recognized as a gain on sale of a private company investment.
Accounting Pronouncements Recently Adopted and Not Yet Adopted	Accounting Pronouncements Recently Adopted Credit Losses : In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses ("ASU 2016-13"). ASU 2016-13 replaces the incurred loss impairment methodology in the current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For trade receivables and other financial instruments, the Company will be required to use a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses which reflects losses that are probable. ASU 2016-13 is effective for public companies with fiscal years beginning after December 15, 2019, with early adoption permitted. Application of the amendments is through a cumulative-effect adjustment to retained earnings as of the effective date. The Company adopted ASU 2016-13, including applicable amendments in other ASUs issued subsequent to ASU 2016-13, with no material impact upon adoption. Accounting Pronouncements Not Yet Adopted Income Taxes : In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ("ASU 2019-12"). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. ASU 2019-12 also improves consistent application and simplifies other areas of Topic 740 by clarifying and amending existing guidance. Early adoption is permitted, provided that the Company reflects any adjustments as of the beginning of the annual period that includes the interim period for which such early adoption occurs. Additionally, the Company must adopt all the amendments in the same period if early adoption is elected. ASU 2019-12 is effective for public companies with fiscal years beginning after December 15, 2020, unless early adopted. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements. Reference Rate Reform : In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 is intended to provide temporary optional expedients and exceptions to the GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the impact this guidance may have on its condensed consolidated financial statements and related disclosures.
