 Exhibit 4.3 

WARRANT ASSUMPTION AGREEMENT 

This Warrant Assumption Agreement (this “Warrant Assumption Agreement”) is entered into as of [●], 2021, by and among
dMY Technology Group, Inc. II, a Delaware corporation (the “dMY”), Galileo NewCo Limited, a company incorporated under the laws of Guernsey (“NewCo”), and Continental Stock Transfer & Trust Company, a New
York corporation (the “Warrant Agent”). 
 WHEREAS, dMY and the Warrant Agent are parties to that certain Warrant Agreement
dated as of August 13, 2020 (the “Warrant Agreement”; capitalized terms used but not otherwise defined herein shall have the meanings given to such terms in the BCA (as defined below)); 

WHEREAS, NewCo, Maven Topco Limited, a company incorporated under the laws of Guernsey (“TopCo”), Maven Midco Limited, a
private limited company incorporated under the laws of England and Wales (“MidCo”), Genius Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of NewCo (“Merger Sub”), dMY Sponsor II, LLC, a
Delaware limited liability company (the “Sponsor”) and dMY are parties to that certain Business Combination Agreement, dated as of October 27, 2020 (as it may be amended, supplemented or otherwise modified from time to time,
the “BCA”), pursuant to which, subject to the terms and conditions set forth therein, Merger Sub will merge with and into dMY, with dMY being the surviving corporation and a wholly owned indirect subsidiary of NewCo (the
“Merger”); and 
 WHEREAS, pursuant to the terms and conditions of each of the Warrant Agreement and the BCA, at the Merger
Effective Time (as defined in the BCA), by virtue of the Merger and without any action on the part of any Party or any other Person, including any holder of dMY Warrants, each dMY Warrant that is outstanding immediately prior to the Merger Effective
Time shall be assumed by NewCo and, by its terms, automatically convert into a warrant exercisable for an equivalent number of NewCo Common Shares (as defined in the BCA) (“NewCo Warrant”), which NewCo Warrants will have the same
terms and be subject to the same conditions as set forth in the Warrant Agreement (other than that any reference to dMY or the “Company” therein should be construed as a reference to NewCo) and in the BCA. 

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, dMY, NewCo and the Warrant Agent hereby agree as follows: 
 1.    Assignment and
Assumption. 
 (a)    Upon the Merger Effective Time, dMY hereby assigns, and NewCo hereby assumes,
the rights and obligations of dMY under the Warrant Agreement and the dMY Warrants, including the obligation to issue NewCo Common Shares upon the exercise of the dMY Warrants, and NewCo hereby agrees to faithfully perform, satisfy and discharge
when due, the liabilities and obligations of dMY under the Warrant Agreement and the dMY Warrants. As a result of the preceding sentence, upon and subject to the occurrence of the Merger Effective Time, each dMY Warrant will be automatically
converted into a NewCo Warrant to purchase NewCo Common Shares pursuant to the terms and conditions of the Warrant Agreement. 












 (b)    NewCo acknowledges and agrees that, subject to
the terms of the Warrant Agreement, the dMY Warrants and this Warrant Assumption Agreement, the Warrant Agreement and the dMY Warrants shall continue in full force and effect and that all of the dMY’s obligations thereunder shall be valid and
enforceable as against NewCo upon the Merger Effective Time and shall not be impaired or limited by the execution or effectiveness of this Warrant Assumption Agreement. 

(c)    This Warrant Assumption Agreement is being executed and delivered pursuant and subject to the
Warrant Agreement. Nothing in this Warrant Assumption Agreement shall, or shall be deemed to, defeat, limit, alter, impair, enhance or enlarge any right, obligation, claim or remedy created by the Warrant Agreement or any other document or
instrument delivered pursuant to or in connection with it. 
 (d)    Notwithstanding the arbitration
provision set forth in the NewCo Governing Documents (as defined in the BCA), the choice of law and jurisdiction provisions set forth in the Warrant Agreement and this Warrant Assumption Agreement shall continue to govern the rights and obligations
of the parties to the Warrant Agreement and this Warrant Assumption Agreement in all respects. NewCo hereby waives any objection to the jurisdiction provision governing the terms of the Warrant Agreement and this Warrant Assumption Agreement. 

2.    Miscellaneous. 

(a)    Governing Law and Jurisdiction. The validity, interpretation, and performance of this Warrant
Assumption Agreement shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. NewCo hereby
agrees that any action, proceeding or claim against it arising out of or relating in any way to this Warrant Assumption Agreement shall be brought and enforced in the courts of the City of New York, County of New York, State of New York or the
United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. NewCo hereby waives any objection to such exclusive jurisdiction and that such courts represent
an inconvenient forum. Any such process or summons to be served upon NewCo may be served by transmitting a copy thereof by registered or certified mail, return receipt requested, postage prepaid, addressed to Donald J. Puglisi, the duly authorized
representative in the United States of NewCo at the address set forth below:
