Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Organization and Business Operations	Note 1—Description of Organization and Business Operations Prime Impact Acquisition I (the “Company”) was incorporated as a Cayman Islands exempted company on July 21, 2020. The Company was incorporated for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies. As of December 31, 2020, the Company had not commenced any operations. All activity for the period from July 21, 2020 (inception) through December 31, 2020 relates to the Company’s formation and the preparation of the initial public offering described below (the “Initial Public Offering”). The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating The Company’s sponsor is Prime Impact Cayman, LLC, a Cayman Islands limited liability company (the “Sponsor”). The registration statement for the Initial Public Offering was declared effective on September 9, 2020. On September 14, 2020, the Company consummated the Initial Public Offering of 30,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units, the “Public Shares”), at $10.00 per Unit, generating gross proceeds of $300.0 million, and incurring offering costs of approximately $17.1 million, inclusive of approximately $10.5 million in deferred underwriting commissions (Note 6). The underwriters were granted a 45-day Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 5,400,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) to the Sponsor, each exercisable to purchase one Class A ordinary share at $11.50 per share, at a price of $1.50 per Private Placement Warrant, generating gross proceeds to the Company of $8.1 million (Note 4). Simultaneously with the closing of the Over-allotment Units, on October 6, 2020, the Company consummated the second closing of the Private Placement, resulting in the purchase of an additional 321,122 Private Placement Warrants by the Sponsor, generating gross proceeds to the Company of approximately $0.5 million. Upon the closing of the Initial Public Offering and the Private Placement, $300.0 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement were placed in a trust account (“Trust Account”) with Continental Stock Transfer & Trust Company acting as trustee and was invested in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, or the Investment Company Act, having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 The Company’s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (net of amounts disbursed to management for working capital purposes, if permitted, and excluding the amount of any deferred underwriting discount) at the time the Company signs a definitive agreement in connection with the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. The Company will provide its holders of the Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). The per-share Notwithstanding the foregoing, the Company’s Amended and Restated Memorandum and Articles of Association provides that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 20% or more of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company. The Company’s Sponsor, executive officers, directors and director nominees have agreed not to propose an amendment to the Company’s Amended and Restated Memorandum and Articles of Association that would affect the substance or timing of the Company’s obligation to provide for the redemption of its Public Shares in connection with a Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment. If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or September 14, 2022 (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share In connection with the redemption of 100% of the Company’s outstanding Public Shares for a portion of the funds held in the Trust Account, each holder will receive a full pro rata portion of the amount then in the Trust Account, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay the Company’s taxes payable (less up to $100,000 of interest to pay dissolution expenses). The Initial Shareholders have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholders should acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company’s Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the trust account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have vendors, service providers (except the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Liquidity and Capital Resources As of December 31, 2020, the Company had approximately $1.6 million in its operating bank account and working capital of approximately $1.3 million. Prior to the completion of the Initial Public Offering, the Company’s liquidity needs had been satisfied through the payment of $25,000 from the Sponsor to cover certain expenses in exchange for the issuance of the Founder Shares (as defined in Note 5), a loan of approximately $98,000 pursuant to the Note issued to the Sponsor (Note 5). The Company repaid the Note in full on September 16, 2020. Subsequent to the consummation of the Initial Public Offering and Private Placement, the Company’s liquidity needs have been satisfied with the proceeds from the consummation of the Private Placement not held in the Trust Account. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor may, but is not obligated to, provide the Company Working Capital Loans (see Note 5). As of December 31, 2020, there were no amounts outstanding under any Working Capital Loan. Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity from the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2—Basis of Presentation and Summary of Significant Accounting Policies Basis of presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has no subsidiaries. Emerging growth company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart Business Startups Act of 2012, (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging Use of estimates The preparation of financial statement in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statement. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statement, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Concentration of credit risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Corporation coverage of $250,000, and investments held in Trust Account. At December 31, 2020, the Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2020. Investments Held in Trust Account The Company’s portfolio of investments held in the Trust Account is comprised of cash and U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities, or a combination thereof. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these investments are included in net gain from investments held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in the Trust Account are determined using available market information, other than for investments in open-ended money market funds with published daily net asset values (“NAV”), in which case the Company uses NAV as a practical expedient to fair value. The NAV on these investments is typically held constant at $1.00 per unit. Fair Value Measurement Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement. Fair Value of Financial Instruments As of December 31, 2020, the carrying values of cash, accounts payable, accrued expenses, and Offering Costs Associated with the Initial Public Offering The Company complies with the requirements of the FASB ASC Topic 340-10-S99-1 ed Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in FASB ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, at December 31, 2020, an aggregate of 30,909,174 Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet. Net Income (Loss) Per Ordinary Share Net income (loss) per ordinary share is computed by dividing net income (loss) by the weighted-average number of ordinary shares outstanding during the period. The Company has not considered the effect of the 10,802,804 warrants sold in the Initial Public Offering and 5,721,122 warrants sold in the Private Placement to purchase an aggregate of 16,523,926 of the Company’s Class A ordinary shares in the calculation of diluted income (loss) per share, since their inclusion would be anti-dilutive under the treasury stock method. The Company’s statement of operations includes a presentation of income (loss) per share for ordinary shares subject to redemption in a manner similar to the two-class for the period from July 21, 2020 (inception) through December 31, 2020, by the weighted average number of Class A ordinary shares outstanding for the period. Net loss per share, basic and diluted for Class B ordinary shares is calculated by dividing the net loss of $169,366, less income attributable to Class A ordinary shares by the weighted average number of Class B ordinary shares outstanding for the period. Income Taxes FASB ASC Topic 740, “Income Taxes” prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of December 30, 2020. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months. Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncement if currently adopted would have a material effect on the Company’s financial statements.

Each whole Private Placement Warrant is exercisable for one whole Class A ordinary share at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants to the Sponsor was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the initial Business Combination.

Related Party Transactions [Abstract]
Related Party Transactions	Note 5—Related Party Transactions Founder Shares On July 23, 2020, the Sponsor paid an aggregate of $25,000 for certain expenses on behalf of the Company in exchange for issuance of 8,625,000 Class B ordinary shares (the “Founder Shares”). The holders of the Founder Shares agreed to forfeit up to an aggregate of 1,125,000 Founder Shares, on a pro rata basis, to the extent that the option to purchase additional units was would were was 0 The Initial Shareholders agreed not to transfer, assign or sell any of their Founder Shares until the earlier to occur of (A) one year after the completion of the initial Business Combination and (B) subsequent to the initial Business Combination, (x) if the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, 30-trading sub-divisions, 30-trading lock-up. Related Party Loans On July 23, 2020, the Sponsor had agreed to loan the Company up to $300,000 to be used for the payment of costs related to the Initial Public Offering pursuant to a promissory note (the “Note”). The Note was non-interest under the Note which was fully repaid on September 16, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor, members of the Company’s founding team or any of their affiliates may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $1.50 per warrant. The warrants would be identical to the Private Placement Warrants. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of December 31, 2020, the Company had no borrowings under the Working Capital Loans. On September 14, 2020, the Company received from the Sponsor $900,000 in advance to purchase up to 600,000 Private Placement Warrants if the over-allotment option was exercised in full. The Sponsor had prefunded the $900,000 assuming the $481,683 . The remaining $418,317 will be refunded to the Sponsor and consequently was reclassified as due to related party. Administrative Services Agreement The Company entered into an agreement that provided that, commencing on the date that the Company’s securities are first listed on the NYSE through the earlier of consummation of the initial Business Combination or the Company’s liquidation, the Company will pay the Sponsor $10,000 per month for office space, secretarial and administrative services. The Company incurred $35,000 in expenses in connection with such services during the period from July 21, 2020 (inception) through December 31, 2020 as reflected in the Administrative expenses - related party on the accompanying statement of operations. As of December 31, 2020, the Company had $35,000 in accrued expenses in connection with such services as reflected in the accompanying balance sheet. In addition, the Sponsor, executive officers and directors, or any of their respective affiliates will be reimbursed for any out-of-pocket

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 6—Commitments and Contingencies Risk and Uncertainties On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus (the “COVID-19 outbreak”). In March 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally. The full impact of the COVID-19 outbreak continues to evolve. The impact of the COVID-19 outbreak on the Company’s results of operations, financial position and cash flows will depend on future developments, including the duration and spread of the outbreak and related advisories and restrictions. These developments and the impact of the COVID-19 outbreak on the financial markets and the overall economy are highly uncertain and cannot be predicted. If the financial markets and/or the overall economy are impacted for an extended period, the Company’s results of operations, financial position and cash flows may be materially adversely affected. Additionally, the Company’s ability to complete an Initial Business Combination may be materially adversely affected due to significant governmental measures being implemented to contain the COVID-19 outbreak or treat its impact, including travel restrictions, the shutdown of businesses and quarantines, among others, which may limit the Company’s ability to have meetings with potential investors or affect the ability of a potential target company’s personnel, vendors and service providers to negotiate and consummate an Initial Business Combination in a timely manner. The Company’s ability to consummate an Initial Business Combination may also be dependent on the ability to raise additional equity and debt financing, which may be impacted by the COVID-19 outbreak and the resulting market downturn. Registration and Shareholder Rights The holders of the Founder Shares, Private Placement Warrants, Class A ordinary shares underlying the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans) are entitled to registration rights pursuant to a registration and shareholder rights agreement. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Underwriting Agreement The Company granted the underwriters a 45-day The underwriters were entitled to an underwriting discount of $0.20 per unit, or $6.0 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per unit, or $10.5 million in the aggregate will be payable to the underwriters for deferred underwriting commissions. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement. If the option to purchase additional units was exercised in full, the underwriters would have been entitled to an aggregate of $900,000 in fees payable upon closing and additional deferred underwriting commissions of approximately $1.6 million. On October 2, 2020, the over-allotment option was partially exercised, resulting in an underwriting discount of approximately $0.5 million deducted from the proceeds received for sale of the Over-Allotment Units, and approximately $0.8 million of deferred underwriting commissions.

In addition, if (x) the Company issues additional Class A ordinary shares or equity linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per Class A ordinary share (with such issue price or effective issue price to be determined in good faith by the board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance), or the Newly Issued Price, (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the volume-weighted average trading price of the ordinary shares during the 20 trading day period starting on the trading day after the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $10.00 and 18.00 per share redemption trigger prices described below under “Redemption of warrants when the price per Class A ordinary share equal or exceed $10.00” and “Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00” will be adjusted (to the nearest cent) to be equal to 100% and 180% of the higher of the Market Value and the Newly Issued Price, respectively. As of December 31, 2020, there were 5,721,122 Private Placement Warrants outstanding. The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable Redemption of warrants for cash when the price per Class A ordinary share equals or exceeds $18.00: Once the warrants become exercisable, the Company may call the outstanding warrants for redemption (except as described herein with respect to the Private Placement Warrants): • in whole and not in part; • at a price of $0.01 per warrant; • upon a minimum of 30 days’ prior written notice of redemption to each warrant holder; and • if, and only if, the last reported sales price (the “closing price”) of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for share sub-divisions, 30-trading Redemption of warrants for Class A ordinary shares when the price per Class A ordinary share equals or exceeds $10.00: Once the warrants become exercisable, the Company may redeem the outstanding warrants: • in whole and not in part; • at $0.10 per warrant upon a minimum of 30 days’ prior written notice of redemption; provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to an agreed table based on the redemption date and the “fair market value” of the Class A ordinary shares; • if, and only if, the Reference Value equals or exceeds $10.00 per Public Share (as adjusted per share sub-divisions, • if the Reference Value is less than $18.00 per share (as adjusted for share sub-divisions, sub-divisions, The Company will not redeem the warrants as described above unless an effective registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the warrants is effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-day The “fair market value” of Class A ordinary shares for the above purpose shall mean the volume-weighted average price of the Class A ordinary shares for the 10 trading days immediately following the date on which the notice of redemption is sent to the holders of warrants. In no event will the warrants be exercisable in connection with this redemption feature for more than 0.361 Class A ordinary shares per warrant (subject to adjustment). In no event will the Company be required to net cash settle any warrant. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

Summary of Significant Accounting Policies (Policies)	5 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Basic of presentation	Basis of presentation The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has no subsidiaries.
Emerging growth company	Emerging growth company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart Business Startups Act of 2012, (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging
Use of Estimates	Use of estimates The preparation of financial statement in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statement. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statement, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.
Concentration of Credit Risk	Concentration of credit risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Corporation coverage of $250,000, and investments held in Trust Account. At December 31, 2020, the Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company did not have any cash equivalents as of December 31, 2020.
Investments Held in Trust Account	Investments Held in Trust Account The Company’s portfolio of investments held in the Trust Account is comprised of cash and U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities, or a combination thereof. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these investments are included in net gain from investments held in Trust Account in the accompanying statement of operations. The estimated fair values of investments held in the Trust Account are determined using available market information, other than for investments in open-ended money market funds with published daily net asset values (“NAV”), in which case the Company uses NAV as a practical expedient to fair value. The NAV on these investments is typically held constant at $1.00 per unit.
Fair Value Measurement	Fair Value Measurement Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include: • Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.
Fair Value of Financial Instruments	Fair Value of Financial Instruments As of December 31, 2020, the carrying values of cash, accounts payable, accrued expenses, and
Offering Costs Associated with the Initial Public Offering	Offering Costs Associated with the Initial Public Offering The Company complies with the requirements of the FASB ASC Topic 340-10-S99-1 ed
Class A Ordinary Shares Subject to Possible Redemption	Class A Ordinary Shares Subject to Possible Redemption The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in FASB ASC Topic 480 “Distinguishing Liabilities from Equity.” Class A ordinary shares subject to mandatory redemption (if any) are classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares are classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, at December 31, 2020, an aggregate of 30,909,174 Class A ordinary shares subject to possible redemption are presented as temporary equity, outside of the shareholders’ equity section of the Company’s balance sheet.
Net Income (Loss) Per Ordinary Share	Net Income (Loss) Per Ordinary Share Net income (loss) per ordinary share is computed by dividing net income (loss) by the weighted-average number of ordinary shares outstanding during the period. The Company has not considered the effect of the 10,802,804 warrants sold in the Initial Public Offering and 5,721,122 warrants sold in the Private Placement to purchase an aggregate of 16,523,926 of the Company’s Class A ordinary shares in the calculation of diluted income (loss) per share, since their inclusion would be anti-dilutive under the treasury stock method. The Company’s statement of operations includes a presentation of income (loss) per share for ordinary shares subject to redemption in a manner similar to the two-class for the period from July 21, 2020 (inception) through December 31, 2020, by the weighted average number of Class A ordinary shares outstanding for the period. Net loss per share, basic and diluted for Class B ordinary shares is calculated by dividing the net loss of $169,366, less income attributable to Class A ordinary shares by the weighted average number of Class B ordinary shares outstanding for the period.
Income Taxes	Income Taxes FASB ASC Topic 740, “Income Taxes” prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of December 30, 2020. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncement if currently adopted would have a material effect on the Company’s financial statements.
