Summary of Significant Accounting Policies (Policies)	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying unaudited consolidated financial statements and related disclosures have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") applicable to interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, all adjustments, consisting of only those of a normal recurring nature, considered necessary for a fair statement of the financial position and interim results of the Company as of and for the periods presented have been included. The December 31, 2021 balance sheet data was derived from audited consolidated financial statements; however, the accompanying interim notes to the consolidated financial statements do not include all of the annual disclosures required by GAAP. Results for interim periods are not necessarily indicative of those that may be expected for a full year. The financial information included herein should be read in conjunction with the Company's consolidated financial statements and related notes in its 2021 Annual Report on Form 10-K.
Revisions to previously issued consolidated financial statements	Revisions to previously issued consolidated financial statements On December 31, 2021 the Company adopted ASU No. 2016-02, Leases (Topic 842) effective from January 1, 2021 using the optional transition approach by applying the new standard to all leases existing at the date of initial application and prior periods were not restated. In connection with the adoption, quarterly amounts presented in our prior Form 10-Q were revised. The impact of the adjustments was immaterial to the Company's consolidated financial statements.
Impact of COVID-19	Impact of COVID-19 The COVID-19 pandemic continues to impact the United States and many countries around the world as new strains of the virus are found. To date, the Company has not experienced material business disruptions or incurred impairment losses in the carrying values of its assets as result of the pandemic, and management is not aware of any specific related event or circumstance that would require the Company to revise the estimates reflected in these consolidated financial statements. The Company continues to monitor the potential impact of the COVID-19 pandemic on its business, results of operations and financial condition. The Company's Travel vertical has experienced a decline in revenue compared with pre-COVID-19 levels, and although management does not believe the situation will materially impact the Company's liquidity or capital position, management does not expect revenue from the travel vertical to recover fully in the foreseeable future. In addition, during the second half of 2021, supply chain disruptions and cost increases caused by the pandemic contributed to higher-than-expected property and casualty insurance claims costs, which has led many carriers to reduce their customer acquisition spending to preserve their profitability. These reductions continue to impact revenue from the Company’s P&C vertical. The extent to which the COVID-19 pandemic will further impact the Company's business, results of operations and financial condition will depend on future developments that is uncertain, including as a result of new information that may emerge concerning COVID-19, the actions taken to contain or treat it, and the duration and intensity of the related effects.
Accounts receivable	Accounts receivable The Company estimates expected credit losses based on collection history and management’s assessment of the current economic trends, business environment, customers’ financial condition, accounts receivable aging and any customer disputes that may impact the level of future credit losses. Accounts receivable are net of allowances for credit losses of $0.5 million and $0.6 million as of March 31, 2022 and December 31, 2021, respectively.
Concentrations of credit risk and of significant customers and suppliers	Concentrations of credit risk and of significant customers and suppliers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains cash balances that can, at times, exceed amounts insured by the Federal Deposit Insurance Corporation. The Company has not experienced any losses in these accounts, and believes it is not exposed to unusual credit risk beyond the normal credit risk in this area based on the financial strength of the institutions with which the Company maintains its deposits. The Company's accounts receivable, which are unsecured, may expose it to credit risk based on their collectability. The Company controls credit risk by investigating the creditworthiness of all customers prior to establishing relationships with them, performing periodic reviews of the credit activities of those customers during the course of the business relationship, regularly analyzing the collectability of accounts receivable, and recording allowances for credit losses. Customer concentrations consisted of one customer that accounted for approximately $19 million, or 13%, of revenue for the three months ended March 31, 2022, compared with three customers that collectively accounted for approximately $68 million, or 39%, of revenue for the three months ended March 31, 2021. There were no customers that accounted for more than 10% of the Company's accounts receivable as of March 31, 2022, compared with the Company's largest customer that accounted for approximately $7 million, or 10%, as of December 31, 2021. The Company’s supplier concentration can expose the Company to business risks. For the three months ended March 31, 2022, the Company had one supplier that accounted for approximately $14 million, or 11%, of total purchases, compared with two suppliers that collectively accounted for approximately $32 million, or 21%, of total purchases for the three months ended March 31, 2021. The Company's largest supplier accounted for approximately $8 million, or 15%, of total accounts payable as of March 31, 2022, compared with the Company's two largest suppliers that collectively accounted for approximately $21 million, or 34%, as of December 31, 2021.
New Accounting Pronouncements	New Accounting Pronouncements Recently issued not yet adopted accounting pronouncements In March 2020 and January 2021, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting and ASU 2021-1, Reference Rate Reform (Topic 848): Scope, respectively. ASU 2020-4 and ASU 2021-1 provide optional expedients and exceptions for applying U.S. GAAP, to contracts, and other transactions that reference the London Interbank Offered Rate or another reference rate expected to be discontinued because of reference rate reform, if certain criteria are met. The guidance in ASU 2020-4 and ASU 2021-1 was effective upon issuance and, once adopted, may be applied prospectively to contract modifications and hedging relationships through December 31, 2022. The Company is currently evaluating the impact of the adoption of ASU 2020-4 and ASU 2021-1 on its consolidated financial statements. In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from contracts with customers, The ASU requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, as if it had originated the contracts. Under the current business combinations guidance, such assets and liabilities were recognized by the acquirer at fair value on the acquisition date. The guidance in ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. The Company is currently evaluating the impact of this ASU, but does not expect the adoption of this standard to have a significant impact on its consolidated financial statements.
