CY2021	us-gaap	Use Of Estimates UseOfEstimates	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Significant estimates and assumptions made by management include determination of stock-based compensation, valuation of embedded derivative, capitalization of software development costs, valuation of contingent consideration, valuation of goodwill and intangible assets, determination of associated useful lives of intangible assets and valuation of deferred tax assets. Management bases its estimates on historical experience and also on assumptions that it believes are reasonable.
CY2021	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company deposits cash with high credit quality financial institutions. All noninterest-bearing accounts are fully insured regardless of the balance of the account. This coverage is available at all FDIC member institutions. The Company uses Silicon Valley Bank, which is an FDIC insured institution. Based on these facts, collectability of bank balances appears to be adequately assured.The Company generally does not require collateral or other security in support of accounts receivable. Allowances will be provided for individual accounts receivable when the Company becomes aware of a customer’s inability to meet its financial obligations, such as in the case of bankruptcy, deterioration in the customer’s operating results, or change in financial position. If circumstances related to customers change, estimates of the recoverability of receivables would be further adjusted. The Company also considers broader factors in evaluating the sufficiency or necessity of an allowance for doubtful accounts, including the length of time receivables are past due, significant onetime events, and historical experience.

CY2021	us-gaap	Derivatives Embedded Derivatives DerivativesEmbeddedDerivatives	In January 2017, the Company issued subordinated promissory notes that contained an embedded derivative, see Note 7 – Debt. At initial recognition, the Company recorded the embedded derivative on the consolidated balance sheet at its estimated fair value resulting in an embedded derivative contra-liability balance with an offsetting recognition of a debt premium. Both the embedded derivative and debt premium were classified together with the related subordinated promissory notes on the consolidated balance sheet. Embedded derivatives are subject to remeasurement at each balance sheet date, with changes in fair value recognized as a component of other gains (losses), net on the consolidated statement of operations. Premium recognized at initial recognition was amortized as a reduction to interest expense over the expected life of the related debt using the effective interest method. In November 2021, in connection with the Company’s IPO, the Company repaid in full the promissory notes, settled the embedded derivative and recognized the remaining unamortized debt premium as an other gain in its consolidated statement of operations.
