## About

Téthys was established in 2016 by Françoise Bettencourt Meyers and her husband Jean-Pierre Meyers. The firm serves as the primary vehicle for the Bettencourt family's investment activities outside their controlling stake in L'Oréal. Jean-Victor Meyers and Nicolas Meyers sit on the board and maintain operational ties to the cosmetics group. The office allocates across private equity, real estate and public markets. It executes buyouts and late-stage direct co-investments, often alongside external partners. Confirmed holdings include a position in Filecoin and participation in The Row alongside Mousse Investments. A separate co-investment with GIC targeted Septeo. Activity spans Europe, North America and Africa. Additional exposure covers EdTech, LegalTech and ClimateTech through both direct and fund vehicles. Téthys maintains its headquarters at 27-29 rue des Poissonniers in Neuilly-sur-Seine. The team includes Alexandre Benais as CEO of the investment subsidiary. The firm also oversees the Bettencourt Meyers private art collection and the family mansion on Rue de Delabordère. In 2021 the family pledged support for the Notre Dame de Paris restoration through the Fondation Bettencourt Schueller. Téthys operates with a concentrated governance structure anchored by the founding couple and their two sons. Board representation at L'Oréal provides direct access to operating-company cash flows and strategic information that shapes external deployment decisions.
