Temporary Equity Disclosure [Abstract]
Redeemable Convertible Preferred Stock	Redeemable Convertible Preferred Stock At December 31, 2021, we are authorized to issue 1,000,000,000 and 100,000,000 shares of common stock and preferred stock, respectively. At December 31, 2020, we were authorized to issue 264,720,000 and 30,512,000 shares of common stock and Series A redeemable convertible preferred stock, or Series A, respectively. Upon the completion of our IPO, 23,081,080 outstanding shares of Series A were converted into 46,162,160 shares of common stock and are no longer issued and outstanding. The Series A contained the following rights and preferences: Dividends The holders of Series A were entitled to receive noncumulative dividends when and if declared by the board of directors. There was no stated dividend rate on the Series A. We could not declare any dividends on any shares of capital stock unless the holders of the Series A then outstanding first receive a dividend on each outstanding share of Series A in an amount at least equal to (i) in the case of a dividend on common stock or any class or series that is convertible into common stock, that dividend per share of Series A as would equal the product of (A) the dividend payable on each share of such class or series determined as if all such shares of such class or series had been converted into common stock and (B) the number of shares of common stock issuable upon conversion of a share of Series A or (ii) in the case of a dividend on any class or series that is not convertible into common stock, at a rate per share of Series A determined by dividing the amount of the dividend payable on each share of such class or series of capital stock by the original issuance price of such class or series of capital stock and multiplying such fraction by an amount equal to $1.50 per share. Conversion Each share of Series A was convertible any time, at the option of the holder, into two shares of common stock whereby the initial issuance price of $1.50 per share is divided by the conversion price of $0.75 per share. All shares of Series A would automatically convert upon the earlier of (i) immediately prior to the closing of the sale of shares of common stock to the public at a price of at least $13.10 per share, in a firm commitment underwritten public offering pursuant to an effective registration statement under the Securities Act of 1933 with at least $100.0 million of gross proceeds to us and with respect to which the common stock is listed for trading on either the New York Stock Exchange or the National Association of Securities Dealers Automated Quotations Exchange, or NASDAQ National Market, each a “qualifying initial public offering,” or (ii) a date specified by the vote of the holders of at least a majority of the then outstanding shares of Series A. Liquidation In the event of any voluntary or involuntary liquidation, dissolution, or winding up, including a merger or consolidation, as defined as a deemed liquidation event under the Certificate of Incorporation, the assets available for distribution to our stockholders would be distributed among the holders of shares of our Series A and common stock, pro rata based on the number of shares held by each such holder, treating for this purpose all such securities as if they had been converted to our common stock immediately prior to such dissolution, liquidation or winding up. We presented our Series A outside of stockholders’ deficit in the mezzanine section of the accompanying consolidated balance sheets, as Series A was contingently redeemable in the case of certain events outside of our control, such as a change in control, or CIC, or sale of substantially all of our assets. Our Series A was not redeemable at the option of the holder. Voting Each holder of outstanding shares of Series A were entitled to cast the number of votes equal to the number of whole shares of common stock into which the shares of Series A held by such holder are convertible as of the record date for determining stockholders entitled to vote on such matter. Holders of Series A will vote together with the holders of common stock as a single class. As long as there were 10,170,668 shares of Series A outstanding, we would not amend, alter or repeal any provision of the Restated Certificate of Incorporation or our By-laws in a manner that adversely affects the rights, preferences, privileges and other restrictions of the Series A; increase or decrease the number of authorized shares of Series A; authorize or enter into any transaction or series of related transactions (i) for the sale, exclusive license or other disposition of a substantial portion of our assets, (ii) for the acquisition of any equity interests or all or substantially all of the assets of another entity, including by merger, in each case, where the fair market value of the consideration paid or issued by us in connection with the transaction exceeds $100.0 million, (iii) for the merger, consolidation or other reorganization with or into another entity, (iv) for our voluntary dissolution or liquidation, or (v) otherwise constituting a change of control, as defined; authorize, designate, issue or reclassify any equity security senior to or on parity with the Series A, with regard to redemption, liquidation preference, voting rights or dividends; increase the size of the board of directors; pay or declare dividends on, make distributions with respect to, or repurchase any shares of our capital stock; incur any aggregate indebtedness for borrowed money in excess of 2.5 times our trailing 12-month cash EBITDA, as defined; increase the number of shares available for grant under our 2000 Stock Option Plan or 2016 Stock Option Plan or authorize or establish any new plan or arrangement providing for the grant or issuance of shares of common stock, options or convertible securities to directors, employees or our consultants; or issue, or commit to issue, any additional shares of Series A. Reserve for Unissued Shares of Common Stock Our policy is to reserve and keep available out of our authorized, unissued shares of common stock such number of shares sufficient to effect the conversion of all outstanding shares of preferred stock plus shares granted and available for grant under our stock option plans.
