Tethys Invest

Tethys Invest is the family investment office of Françoise Bettencourt Meyers, heiress to the L’Oréal fortune and the wealthiest woman in the world. With an estimated net worth of approximately $90 billion, the Bettencourt Meyers family’s wealth is primarily derived from their approximately 35% controlling stake in L’Oréal, the global leader in cosmetics and beauty products. Tethys Invest manages the family’s financial affairs, including the L’Oréal stake and diversified investments.

Investment Strategy

The Bettencourt family’s wealth traces to Eugène Schueller, who founded L’Oréal in 1909 and built it into what would become the world’s largest beauty company. The family maintained its controlling position across three generations, with the stake passing from Schueller to his daughter Liliane Bettencourt and subsequently to Françoise Bettencourt Meyers.

L’Oréal’s market capitalization, which has exceeded $250 billion, makes the family’s approximate 35% stake worth over $85 billion. The company operates 37 brands across four divisions (consumer products, L’Oréal Luxe, professional products, and dermatological beauty) and generates approximately $45 billion in annual revenue. The Bettencourt family exercises its controlling interest through board representation and the family’s historic position as L’Oréal’s anchor shareholder.

A significant structural event occurred in 2023 when Nestlé completed its exit from L’Oréal, ending a shareholder relationship that had lasted since 1974. Nestlé’s departure, facilitated through share buybacks, simplified L’Oréal’s shareholder structure and reinforced the Bettencourt family’s dominant position.

Tethys Invest manages diversified investments beyond the L’Oréal stake, though the concentration in L’Oréal means that the family’s overall financial position is highly correlated with the company’s stock performance. The investment office maintains allocations across public equities, fixed income, real estate, and select private investments.

Private Markets Approach

Tethys Invest’s private markets activity, while less publicly visible than some family offices of comparable wealth, includes investments in technology, health care, and consumer-related ventures. The family office has participated in venture capital investments in France and Europe, contributing to the growth of the French technology and startup ecosystem.

The family’s real estate holdings include properties in Paris and the south of France, consistent with the family’s deep roots in French business and society. These holdings represent private assets managed alongside the more liquid financial portfolio.

The Bettencourt Schueller Foundation, one of the largest philanthropic organizations in Europe, represents a major allocation of family resources toward social impact. The foundation’s focus on scientific research, arts and culture, and social solidarity channels significant capital into grants, fellowships, and institutional support. The foundation’s contribution to the restoration of Notre-Dame Cathedral following the 2019 fire was among the most prominent donations from French business families.

Fund managers seeking engagement with Tethys Invest should understand that the family office operates with a degree of privacy unusual even among European family offices. The Bettencourt family has historically maintained a low public profile regarding investment activities outside L’Oréal. Investment relationships are built through established networks within the French business and financial community, and the office favors long-term, relationship-based engagement over transactional fund commitments.
