Registration Statement on Form S-1 filed August 18, 2020 Risk Factors Compliance obligations under the Sarbanes-Oxley Act may make it more difficult ..., page 62 1. You disclose that Section 404 of the Sarbanes-Oxley Act requires you to evaluate and report on your system of internal controls beginning with your annual report on Form 10- K for the year ending December 31, 2021; however, we note your fiscal year ends on March 31 and we note you disclose on page 108 that you will be required to evaluate internal control procedures for the fiscal year ending March 31, 2022. Please revise your disclosure to correct this discrepancy. George Syllantavos FirstName LastNameGeorge Syllantavos Growth Capital Acquisition Corp.

You appropriately disclose on page 71 that your net tangible book value at June 30, 2020 was $(17,957); however, you disclose on page 72 that net tangible book value before the offering was $2,043. Please revise your disclosure to correct this discrepancy. In addition, we note your disclosures related to the private placement stockholders on page 72 appear to exclude the shares of Class B common stock that they recently acquired. Please clarify or revise your disclosures. Please also revise your disclosures on pages 16 and F-11 to explain why the sponsor forfeited 2,833,333 shares of Class B common stock to the company for no consideration on August 14, 2020 and why the private placement stockholders each purchased 1,379,167 shares of Class B common stock from the company for an aggregate purchase price of $4 million.

You disclose on page 75 that deferred offering costs were $0 as of June 30, 2020; however, based on your balance sheet on page F-3, we note you recorded deferred offering costs of $20,000 as of June 30, 2020. Please correct your disclosures here and on page 34 to agree with your balance sheet. Exclusive forum for certain lawsuits, page 134 4. We note that your provision states that the Court of Chancery and the federal district court for the District of Delaware shall have concurrent jurisdiction for any action arising under the Securities Act. However, this is inconsistent with your disclosure that the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Securities Act or any other claim for which the federal and state courts have concurrent jurisdiction. Please revise your disclosure here and on page 63. Experts, page 153 5. We note your response to prior comment 1; however, we note compliance with Item 304 of Regulation S-K is required "if during the registrant s two most recent fiscal years or any subsequent interim period, an independent accountant who was previously engaged as the principal accountant to audit the registrant s financial statements has resigned (or indicated it has declined to stand for re-election after the completion of the current audit) or was dismissed." Since the change in your auditor occurred on August 5, 2019, it continues to appear to us that you are required to comply with Item 304 of Regulation S-K in the current registration statement as the disclosure requirement is based on the date that the change in auditor occurred rather than the date of its audit report or the date of the financial statements it audited.
