Note: Schedules filed in paper format shall include a signed original and five copies of the schedule, including all exhibits. See §240.13d-7 for other parties to whom copies are to be sent.

The information required on the remainder of this cover page shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934 (“Act”) or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

This Amendment No. 2 (the “Amendment”) amends and supplements the Schedule 13D filed by the Reporting Persons on December 1, 2022, as amended and supplemented by Amendment No. 1 on January 6, 2023 (collectively, the “Original Schedule 13D” and, as amended and supplemented by this Amendment, the “Statement”), with respect to the Class A Common Shares. Capitalized terms used in this Amendment and not otherwise defined shall have the same meanings ascribed to them in the Original Schedule 13D.

On January 6, 2023 and January 11, 2023, General Atlantic, together with certain affiliated entities, filed amendments to their Schedule 13D with respect to the Company (the “GA Schedule 13D Amendments”). This Amendment updates Item 5 of the Statement to reflect certain information disclosed in the GA Schedule 13D Amendments and to reflect an increase in the number of Class A Common Shares outstanding and a corresponding decrease in the percentage of that class of securities beneficially owned by the Reporting Persons and other persons identified in Item 5.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated in its entirety.

The information contained in rows 7, 8, 9, 10, 11 and 13 on each of the cover pages of this Statement is incorporated by reference in its entirety into this Item 5.

As the managing member of Dragoneer Adviser, Cardinal DIG CC, LLC may also be deemed to share voting and dispositive power with respect to the Class A Common Shares (including the Class A Common Shares issuable upon conversion of 2028 Convertible Notes). Marc Stad is the sole member of Cardinal DIG CC, LLC. By virtue of these relationships, each of the Reporting Persons may be deemed to share beneficial ownership of the Class A Common Shares of the Company (including the Class A Common Shares issuable upon conversion of 2028 Convertible Notes).

None of the Reporting Persons nor, to the best knowledge of the Reporting Persons, without independent verification, any person named in Item 2 hereof, has effected any transaction in Class A Common Shares during the past 60 days.

To the best knowledge of the Reporting Persons, no person other than the Reporting Persons has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities beneficially owned by the Reporting Persons identified above in this Item 5.

By virtue of submitting the Proposal, the Reporting Persons may be deemed to be members of a “group” with General Atlantic and the Founders that own Class A Common Shares and Class B Common Shares pursuant to Section 13(d) of the Exchange Act as a result of jointly submitting the proposal. However, each Reporting Person expressly disclaims beneficial ownership of the Class A Common Shares beneficially owned by any other person(s), General Atlantic or the Founders. Neither the filing of this Statement nor any of its contents shall be deemed to constitute an admission that any of the Reporting Persons beneficially owns any Class A Common Shares or Class B Common Shares of the Company that are beneficially owned by any other person(s), General Atlantic or the Founders. The Reporting Persons are only responsible for the information contained in this Statement and assume no responsibility for information contained in any other Schedules 13D filed by any other reporting person(s), General Atlantic or the Founders.

Based on the GA Schedule 13D Amendments, General Atlantic, together with its affiliated funds, beneficially owns 5,827,504 Class A Common Shares including 1,724,138 Class A Common Shares issuable upon conversion of all of the 2028 Convertible Notes beneficially owned by General Atlantic and 4,103,366 Class A Common Shares. Based on (i) 29,450,551 Class A Common Shares reported outstanding as of April 8, 2022 in the Company’s Form 6-K filed with the SEC on April 13, 2022 (the “Form 6-K”), (ii) 10,436,202 Class A Common Shares issued by the Company in connection with the Company’s acquisition of isaac, as announced by the Company in its press release dated January 3, 2023 (the “January 3 Press Release”) and (iii) 1,724,138 Class A Common Shares issuable upon conversion of all of the 2028 Convertible Notes beneficially owned by General Atlantic, General Atlantic beneficially owns approximately 14% of the outstanding Class A Common Shares, as calculated in accordance with Rule 13d-3(d)(1)(i). The GA Schedule 13D Amendments state that a fund affiliated with General Atlantic, as a shareholder of isaac, acquired 2,919,432 Class A Common Shares in connection with the Company’s acquisition of isaac, which closed on January 2, 2023, in consideration for the shares of isaac owned by that fund. The GA Schedule 13D Amendments further state that such fund may be entitled to receive up to an additional 121,644 Class A Common Shares that are subject to holdback provisions for a period of eighteen months in connection with the acquisition of isaac by the Company.

The percentage of total voting power represents voting power with respect to all Class A Common Shares and Class B Common Shares, as a single class. Each Class B Common Share may be converted into one Class A Common Share at the option of the holder.

Based on Amendment No. 1 to Schedule 13D filed by Ari de Sá Cavalcante Neto and the other reporting person therein with the SEC on January 11, 2023, Ari de Sá Cavalcante Neto and the other reporting person beneficially own 344,182 Class A Common Shares and 8,297,485 Class B Common Shares, which represent approximately 17.9% of the total number of Class A Common Shares based on (i) 29,450,551 Class A Common Shares reported outstanding as of April 8, 2022 in the Form 6-K, (ii) 10,436,202 Class A Common Shares issued by the Company in connection with the Company’s acquisition of isaac, as announced by the Company in the January 3 Press Release and (iii) 8,297,485 Class A Common Shares issuable upon conversion of the Class B Common Shares, approximately 30.3% of Class B Common Shares outstanding and voting power of approximately 26.5%.
