Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Organization, Business Operations and Basis of Presentation	Description of Organization and Business Operations Organization and General ARYA Sciences Acquisition Corp III (the “Company”) was incorporated as a Cayman Islands exempted company on March 27, 2020. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share 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. All activity for the period from March 27, 2020 (inception) through December 31, 2020 relates to the Company’s formation and its initial public offering (“Initial Public Offering”), and since the closing of the Initial Public Offering, the search for a prospective initial Business Combination. 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 income in the form of interest income on cash and cash equivalents and gains on investments from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end. Sponsor and Initial Public Offering The Company’s sponsor is ARYA Sciences Holdings III, a Cayman Islands exempted limited company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on August 6, 2020. On August 11, 2020, the Company consummated its Initial Public Offering of 14,950,000 Class A ordinary shares (the “Public Shares”), including the 1,950,000 Public Shares as a result of the underwriters’ full exercise of their over-allotment option, at an offering price of $10.00 per Public Share, generating gross proceeds of $149.5 million, and incurring offering costs of approximately $8.8 million, inclusive of approximately $5.2 million in deferred underwriting commissions (Note 5). Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 499,000 Class A ordinary shares (the “Private Placement Shares”), at a price of $10.00 per Private Placement Share to the Sponsor, generating gross proceeds of approximately $5.0 million (Note 4). Trust Account Upon the closing of the Initial Public Offering and the Private Placement, $149.5 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”), located in the United States at J.P. Morgan Chase Bank, N.A., with Continental Stock Transfer & Trust Company acting as trustee, and were invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of:(i) the completion of a Business Combination, and then only in connection with those Class A ordinary shares that the holders of public shares (the “Public Shareholders”) properly elected to redeem, subject to certain limitations described in the IPO Registration Statement, (ii) the redemption of any Public Shares properly tendered in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association (the “Amended and Restated Memorandum and Articles of Association”) (A) to modify the substance or timing of the Company’s obligation to provide holders of Class A ordinary shares the right to have their shares redeemed in connection with the Company’s initial Business Combination or to redeem 100% of the Company’s Public Shares if the Company does not complete its initial Business Combination within 24 months from the closing of the Initial Public Offering, or October 26, 2022 (the “Combination Period”) or (B) with respect to any other provision relating to the rights of holders of Class A ordinary shares, and (iii) the redemption of the Class A ordinary shares if the Company has not consummated its Business Combination within the Combination Period, subject to applicable law. The remaining net proceeds (not held in the Trust Account) may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses. The Company may use the interest income generated by the assets in the Trust Account to pay for taxes that were paid by the Company or are payable by the Company and, in case the Company does not complete its initial Business Combination within the Combination Period, $100,000 of the interest income may be used to pay dissolution expenses. Initial Business Combination The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (excluding the amount of deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of the signing of the agreement to enter into 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 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 Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay income taxes). The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to Goldman Sachs & Co. LLC and Jefferies LLC, as underwriters of the Company’s Initial Public Offering (as discussed in Note 5). The Public Shares are classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, only if a majority of the ordinary shares, represented in person or by proxy and entitled to vote thereon, voted at a shareholder meeting are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to the Amended and Restated Memorandum and Articles of Association, conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or other reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or vote at all. If the Company seeks shareholder approval in connection with a Business Combination, the initial shareholders (as defined below) have agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. Subsequent to the consummation of the Initial Public Offering, the Company has adopted an insider trading policy which requires insiders to: (i) refrain from purchasing shares during certain blackout periods and when they are in possession of any material non-public information and (ii) to clear all trades with the Company’s legal counsel prior to execution. In addition, the initial shareholders have agreed to waive their redemption rights with respect to their Founder Shares, Private Placement Shares and Public Shares in connection with the completion of a Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of its Business Combination and does not conduct redemptions in connection with its Business Combination pursuant to the tender offer rules, the 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 15% of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company. The Company’s Sponsor, officers and directors (the “initial shareholders”) have agreed not to propose an amendment to the Amended and Restated Memorandum and Articles of Association (a) that would modify the substance or timing of the Company’s obligation to provide holders of its Public Shares the right to have their shares redeemed in connection with a Business Combination or to redeem 100% of the Company’s Public Shares if the Company does not complete its Business Combination within 24 months from the closing of the Initial Public Offering, or August 11, 2022 (the “Combination Period”) or with respect to any other provision relating to the rights of Public Shareholders, 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 has not completed a Business Combination within 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 price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay for its income taxes, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number of the then-outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and its board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii) to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The initial shareholders have agreed to waive their liquidation rights with respect to the Founder Shares and Private Placement Shares held by them if the Company fails to complete a Business Combination within the Combination Period. However, if the initial shareholders 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 5) 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 other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the 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 to be liable to the Company if and to the extent any claims by a third party (excluding the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction 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 Public Share due to reductions in the value of the assets in the Trust Account, in each case net of the interest that may be withdrawn to pay for the Company’s tax obligations. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or 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”). Moreover, 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 all vendors, service providers (excluding 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. The Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor’s only assets are securities of the Company. The Sponsor may not be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses. Proposed Nautilus Business Combination and related Proposed Transactions On February 7, 2021, we entered into a business combination agreement (“Business Combination Agreement”), by and among the Company, Mako Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and Nautilus Biotechnology, Inc., a Delaware corporation (“Nautilus”). The Business Combination Agreement provides for, among other things, the following transactions: (i) Nautilus will changes its name to “Nautilus Subsidiary, Inc.” (or another name mutually agreed to by us and Nautilus); (ii) we will become a Delaware corporation (the “Domestication”) and, in connection with the Domestication, (A) our name will be changed to “Nautilus Biotechnology, Inc.” (“New Nautilus”) and (B) each of our outstanding Class A ordinary shares and outstanding Class B ordinary shares will become one share of common stock of New Nautilus (the “New Nautilus Common Stock”); and (iii) following the Domestication, Merger Sub will merge with and into Nautilus, with Nautilus as the surviving company in the merger and, after giving effect to such merger, continuing as a wholly-owned subsidiary of New Nautilus (the “Merger”). The Domestication, the Merger and the other transactions contemplated by the Business Combination Agreement are hereinafter referred to as the “Nautilus Business Combination.” In accordance with the terms and subject to the conditions of the Business Combination Agreement, outstanding shares of Nautilus (other than treasury shares and any Company Dissenting Shares (as defined in the Business Combination Agreement) will be exchanged for shares of New Nautilus Common Stock and outstanding Nautilus options to purchase shares of Nautilus (whether vested or unvested) will be exchanged for comparable options to purchase New Nautilus Common Stock, in each case, based on an implied Nautilus equity value of $900 million. The Nautilus Business Combination is expected to close in the second quarter of 2021, following the receipt of the required approval by our shareholders and the fulfillment of other customary closing conditions. Concurrently with the execution of the Business Combination Agreement, the Company, the Sponsor, and each other holder of Class B ordinary shares of ARYA (the “Other Class B Shareholders”) and Nautilus entered into the Sponsor Letter Agreement (the “Sponsor Letter Agreement”), pursuant to which the Sponsor and the Other Class B Shareholders, among other things, (i) vote in favor of each of the transaction proposals to be voted upon at the meeting of ARYA shareholders, including approval of the Business Combination Agreement and the transactions contemplated thereby (including the Merger) and (ii) waive any adjustment to the conversion ratio set forth in the governing documents of the Company or any other anti-dilution or similar protection with respect to the Class B ordinary shares (whether resulting from the transactions contemplated by the Subscription Agreements (as defined below) or otherwise); and (iii) be bound by certain transfer restrictions with respect to his, her or its shares in the Company prior to the closing of the Nautilus Business Combination, in each case, on the terms and subject to the conditions set forth in the Sponsor Letter Agreement. Concurrently with the execution of the Business Combination Agreement, we entered into subscription agreements (the “Subscription Agreements”) with certain investors, including, among others, Perceptive Life Sciences Master Fund Ltd., a fund managed by Perceptive Advisors, an affiliate of the Sponsor, as well as certain equity holders of Nautilus and additional third party investors. Pursuant to the Subscription Agreements, each investor agreed to subscribe for and purchase, and the Company agreed to issue and sell to such investors, on the Closing Date (as defined in the Business Combination Agreement) immediately prior to the Closing (as defined in the Business Combination Agreement), an aggregate of 20,000,000 shares of the New Nautilus Common Stock for a purchase price of $10.00 per share, for aggregate gross proceeds of $200,000,000. Within 24 hours of the signing of the Business Combination Agreement, certain directors, officers and stockholders of Nautilus entered into a Transaction Support Agreement with the Company, pursuant to which such parties have agreed to, among other things, (i) support and vote in favor of the Business Combination Agreement and the transactions contemplated thereby (including the Merger), and (ii) be bound by certain other covenants and agreements related to the Nautilus Business Combination, including a restriction on transfers with respect to his, her or its shares in Nautilus prior to the closing of the Nautilus Business Combination The Company, the Perceptive Shareholders (as defined in the Business Combination Agreement), the Other Class B Shareholders and certain Nautilus shareholders entered into an amended and restated registration rights and lock-up agreement, pursuant to which, among other things, the Perceptive Shareholders, the Other Class B Shareholders and the certain Nautilus shareholders agreed not to effect any sale or distribution of the company equity securities during the lock-up period described therein and will be granted certain customary registration rights, in each case subject to, and conditioned upon and effective as of, the effective time of the Merger. A copy of each of the above referenced agreements is filed as exhibits with a Current Report on Form 8-K, filed with the SEC on February 8, 2021. Liquidity and Capital Resources As of December 31, 2020, the Company had approximately $1.0 million in its operating bank account and working capital of approximately $916,000. The Company’s liquidity needs to date have been satisfied through a contribution of $25,000 from the Sponsor to cover certain of the Company’s offering costs in exchange for the issuance of the Founder Shares, the loan proceeds of $200,000 from the Sponsor pursuant to the Note (see Note 4), and the proceeds from the consummation of the Private Placement not held in the Trust Account. The Company fully repaid the Note on August 11, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, provide the Company Working Capital Loans (see Note 4). 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. 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. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Summary of Significant Accounting Policies	9 Months Ended
Summary of Significant Accounting Policies	Dec. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC. Use of Estimates The preparation of the financial statements 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 statements and the reported amounts of expenses during the reporting period. Making estimates requires management to exercise significant judgment. 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 statements, 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 from those estimates. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our 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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, 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 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 growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. 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 had $1,926 in cash equivalents as of December 31, 2020 held in the Trust Account. 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 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. Investment Securities Held in Trust Account Upon the closing of the Initial Public Offering and the Private Placement, the Company was required to place net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement in a Trust Account, which may be invested in 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 in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by management of the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account. Investments held in Trust Account are classified as trading securities, which are presented on the balance sheet at fair value at the end of the reporting period. Gains and losses resulting from the change in fair value of trading securities is included in investment income on Trust Account in the accompanying statement of operations. The estimated fair values of investments held in 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 Measurements 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. 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 (unadjusted) 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. As of December 31, 2020, the carrying values of cash, prepaid expenses and accrued expenses approximate their fair values due to the short-term nature of the instruments. The Company’s investments held in Trust Account is comprised of investments in U.S. Treasury securities with an original maturity of 180 days or less and are recognized at fair value. The fair value of investments held in Trust Account is determined using quoted prices in active markets. Offering Costs Associated with the Initial Public Offering Offering costs consisted of underwriters' commissions, legal, accounting, and other costs incurred that were directly related to the Initial Public Offering and that were charged to shareholders’ equity upon the completion of the Initial Public Offering. 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 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, 14,023,673 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 share is computed by dividing net income by the weighted-average number of ordinary shares outstanding during the period. 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 method of income per share. Net income per ordinary share, basic and diluted, for Class A ordinary shares is calculated by dividing the net gain, dividends and interest on investments held in Trust Account, net of applicable taxes available to be withdrawn from the Trust Account, resulting in net income of approximately $53,000 for the period from March 27, 2020 (inception) through December 31, 2020 by the weighted average number of Class A ordinary shares outstanding for the period. Net loss per ordinary share, basic and diluted for Class B ordinary shares is calculated by dividing the net loss, less income attributable to Class A ordinary shares by the weighted average number of Class B ordinary shares outstanding for the period. Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, “Income Taxes,” which 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 31, 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. There were no unrecognized tax benefits and no amounts were accrued for interest and penalties for the period from March 27, 2020 (inception) through 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 may be subject to potential examination by U.S. federal, U.S. state or foreign taxing authorities in the area of income taxes. These potential examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with U.S. federal, U.S. state and foreign tax laws. There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman federal income tax regulations, income taxes are not levied on the Company. Consequently, deferred tax assets and 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 The Company’s management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	Related Party Transactions Founder Shares On April 2, 2020, the Sponsor paid $25,000 to cover certain offering costs of the Company in consideration of 3,593,750 Class B ordinary shares, par value $0.0001 per share (the “Founder Shares”). In July 2020, the Sponsor transferred an aggregate of 90,000 Founder Shares to the Company’s independent directors. On August 6, 2020, the Company effected a share capitalization resulting in the initial shareholders holding 3,737,500 Founder Shares. All shares and the associated amounts have been retroactively restated to reflect the share capitalization. The Sponsor agreed to forfeit up to 487,500 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters, so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding ordinary shares (excluding the Private Placement Shares) after the Initial Public Offering. The underwriters fully exercised the over-allotment option on August 11, 2020; thus, these 487,500 Founder Shares were no longer subject to forfeiture. The initial shareholders agreed, subject to limited exceptions, 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 Company’s Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the Public Shareholders having the right to exchange their ordinary shares for cash, securities or other property. Private Placement Shares Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 499,000 Private Placement Shares, at a price of $10.00 per Private Placement Share to the Sponsor, generating gross proceeds of approximately $5.0 million. The Private Placement Shares will not be transferable or salable until 30 days after the completion of the initial Business Combination. A portion of the proceeds from the Private Placement Shares was added to the proceeds from the Initial Public Offering held in the Trust Account. 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 Shares until 30 days after the completion of the initial Business Combination. Related Party Loans On April 2, 2020, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover for expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan was non-interest bearing and payable upon the completion of the Initial Public Offering. The Company borrowed $200,000 under the Note and fully repaid this Note on August 11, 2020. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors 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 may repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans may 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 the 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. 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. 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 shares of the post Business Combination entity at a price of $10.00 per share. The shares would be identical to the Private Placement Shares. As of December 31, 2020, the Company had no outstanding borrowings under the Working Capital Loans. Administrative Support Agreement Commencing on the date that the Company’s securities were first listed on the Nasdaq through the earlier of consummation of the initial Business Combination and the Company’s liquidation, the Company reimburses the Sponsor for office space, secretarial and administrative services provided to the Company in the amount of $10,000 per month. The Company incurred approximately $48,000 for these services and are in general and administrative expenses in the accompanying statement of operations for the period from March 27, 2020 (inception) through December 31, 2020.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the financial statements 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 statements and the reported amounts of expenses during the reporting period. Making estimates requires management to exercise significant judgment. 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 statements, 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 from those estimates.
Cash and Cash Equivalents, Policy [Policy Text Block]	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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments & Contingencies Registration Rights The holders of Founder Shares, Private Placement Shares and Private Placement Shares that may be issued upon conversion of Working Capital Loans, will be 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 Company’s completion of its Business Combination. However, the registration and shareholder rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period, which occurs (i) in the case of the Founder Shares, in accordance with the letter agreement the Company’s initial shareholders entered into and (ii) in the case of the Private Placement Shares, 30 days after the completion of the Company’s 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 option from the final prospectus relating to the Initial Public Offering to purchase up to 1,950,000 additional Public Shares to cover over-allotments, at the Initial Public Offering price less the underwriting discounts and commissions. On August 11, 2020, the underwriters fully exercised the over-allotment option. The underwriters were entitled to an underwriting discount of $0.20 per Public Share, or approximately $3.0 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per Public Share, or approximately $5.2 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.

Equity [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	Shareholders’ Equity Class A Ordinary Shares — The Company is authorized to issue 479,000,000 Class A ordinary shares with a par value of $0.0001 per share. As of December 31, 2020, there were 15,449,000 Class A common shares outstanding, including 14,023,673 Class A ordinary shares common stock subject to possible redemption that were classified as temporary equity in the accompanying balance sheet. Class B Ordinary Shares — The Company is authorized to issue 20,000,000 Class B ordinary shares with a par value of $0.0001 per share. On April 2, 2020, the Company issued 3,593,750 Class B ordinary shares. On August 6, 2020, the Company effected a share capitalization resulting in the initial shareholders holding 3,737,500 Founder Shares, of which up to 487,500 shares were subject to forfeiture to the Company by the Sponsor for no consideration to the extent that the underwriter’s over-allotment option is not exercised in full or in part, so that the initial shareholders would collectively own 20% of the Company’s issued and outstanding ordinary shares (excluding the Private Placement Shares). All shares and the associated amounts have been retroactively restated to reflect the share capitalization. The underwriters fully exercised the over-allotment option on August 11, 2020; thus, the 487,500 Founder Shares were no longer subject to forfeiture. Holders of the Class A ordinary shares and holders of the Class B ordinary shares will vote together as a single class on all matters submitted to a vote of our shareholders, except as required by law or stock exchange rule; provided that only holders of the Class B ordinary shares have the right to vote on the election of the Company’s directors prior to the initial Business Combination and holders of a majority of the Company’s Class B ordinary shares may remove a member of the board of directors for any reason. The Class B ordinary shares will automatically convert into Class A ordinary shares on the first business day following the consummation of the initial Business Combination at a ratio such that the number of Class A ordinary shares issuable upon conversion of all Founder Shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of (i) the total number of ordinary shares issued and outstanding (excluding the Private Placement Shares) upon the consummation of the Initial Public Offering, plus (ii) the sum of the total number of Class A ordinary shares issued or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial Business Combination, excluding any Class A ordinary shares or equity-linked securities exercisable for or convertible into Class A ordinary shares issued, deemed issued, or to be issued, to any seller in the initial Business Combination and any Private Placement Shares issued to the Sponsor, members of the Company’s management team or any of their affiliates upon conversion of Working Capital Loans. In no event will the Class B ordinary shares convert into Class A ordinary shares at a rate of less than one-to one. Preference Shares — The Company is authorized to issue 1,000,000 preference shares with a par value of $0.0001 per share and with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of December 31, 2020, there were no preference shares issued or outstanding.
