What’s the largest French family office by AUM?

While for other countries like the United States, Germany, UK or Japan, or team had to weigh up different options for the #1 rank of the respective largest family office in the country, the decision was quite straightforward in France. Our experienced familyofficehub.io research team concluded that Bernard Arnault’s family office Financière Agache SA (alongside Groupe Arnault and Aglae Ventures) is the largest French family office, managing Arnault’s net worth of over $150 billion.

How does Financiere Agache invest?

The Financière Agache family office, controlled by Bernard Arnault, plays a central role in managing the Arnault family’s wealth and investments. As part of a broader structure that includes Groupe Arnault and Aglaé Ventures, it is responsible not only for preserving capital but also for identifying long-term growth opportunities. While much of the Arnault family’s fortune remains concentrated in LVMH—where they hold a controlling stake—Financière Agache has expanded its scope beyond luxury into diverse sectors such as technology, digital health, and consumer services.

In 2022, the family office underwent a legal restructuring into a joint-stock partnership to strengthen family control and ensure protection against potential takeover attempts. This change reflects Bernard Arnault’s long-standing emphasis on governance and continuity. Through its investment arms, particularly Aglaé Ventures, the family office has backed a wide range of ventures, including early investments in Netflix, Spotify, and Airbnb, as well as recent funding rounds in artificial intelligence firms such as H (formerly Holistic AI), Proxima, and Lamini.

Financière Agache also contributes to strategic acquisitions in partnership with firms like L Catterton, as demonstrated by the acquisition of a majority stake in Birkenstock. In addition to managing financial assets, the family office oversees the execution of philanthropic activities and facilitates intergenerational succession planning.

Alternative candidates for the French family office ranking by AUM

Since the net worth of the Arnault family by far exceeds the one of alternative candidates, our familyofficehub.io team quickly decided on the #1 rank. However, there are several high-profile family offices in France. For instance, L’Oreal heir Françoise Bettencourt Meyers manages the family wealth through the Téthys family office, the Pinault family office invests through Group Artemis, and the Wertheimer family invests via Mousse Partners.
