Wertheimer Family Office Invests in $6.6 billion Rockefeller Deal

Rockefeller Capital Management announced a major recapitalization at an enterprise valuation exceeding $6.6 billion on October 14, 2025, welcoming a new investor group led by Mousse Partners (the Wertheimer family office), Progeny 3, and Abrams Capital alongside existing investors Viking Global Investors and the Rockefeller and Desmarais (through IGM Financial) families. The transaction, anticipated to close by December 31, 2025, marks a significant milestone in the firm’s growth trajectory and underscores the strength of its strategic expansion plans. CEO Gregory J. Fleming emphasized that the partnership reinforces Rockefeller’s unwavering commitment to delivering exceptional outcomes for its clients while remaining steadfast in its strategic focus and day-to-day operations. The firm, which manages $187 billion in client assets as of September 30, 2025, will continue operating its three divisions—Rockefeller Global Family Office, Rockefeller Asset Management, and Rockefeller Global Investment Banking—across 32 U.S. markets and London. Viking Global Investors remains the firm’s largest investor, continuing an eight-year partnership instrumental in shaping Rockefeller’s trajectory.

About Mousse Partners – the Wertheimer family office

Mousse Partners, which leads the new investor group alongisde Progeny 3 and Abrams Capital, serves as the family office managing the wealth of Alain and Gérard Wertheimer, the renowned owners of the French luxury fashion house Chanel. Founded in 1991 to structure and manage Chanel’s fortunes and those of its owners, Mousse Partners has evolved into a sophisticated investment firm engaged in private equity, venture capital, real estate, and credit investments across public and private markets. The family office has its headquarters in New York. The Wertheimer family’s investment through Mousse Partners reflects their strategic approach to diversifying into leading wealth management platforms, complementing their previous high-profile transactions, such as their involvement in the Rothschild & Co. deal announced in 2023. Back then, the Wertheimer family office allegedly had supported the delisting of Rothschild, alongside the Peugeot, Dassault, and Rothschild families.
