Mousse Partners

Mousse Partners is the investment division of Mousse Investments Limited, functioning as the single-family office for the Wertheimer family, who are the owners of the luxury fashion house Chanel. The firm manages a global, diversified portfolio with a long-term investment horizon, allocating capital across both public and private markets. They engage in a broad range of asset classes, including private equity, venture capital, real estate, and credit investments. Mousse Partners values deep and collaborative relationships, partnering with select external investment managers and also investing directly alongside high-quality management teams, entrepreneurs, and other institutional investors.

The firm was founded in 1991 by Charles Heilbronn, a Chanel executive and half-brother to Alain and Gérard Wertheimer, the current owners of Chanel. Its primary purpose was to structure and manage the fortunes of the Wertheimer family and Chanel itself. Mousse Partners was originally a subsidiary of Mousse Investments Limited until a merger in December 2018, after which it became the investment division of the holding company.

Mousse Partners has made numerous notable investments across various sectors. Its portfolio includes companies such as CAVA, a fast-casual Mediterranean restaurant chain; Whoop, a provider of wearable technology for health and fitness; Tonal, an AI-based digital home gym system; and Brightside Health, a virtual mental healthcare platform. Other significant investments include Epigamia, an online brand of healthy food products; Thirty Madison, a healthcare platform; and Nature's Fynd, a provider of fungi-based dairy products. The firm has seen several of its portfolio companies achieve unicorn status, such as Tonal and Whoop, and has also experienced successful acquisitions and IPOs, including CAVA.

The team at Mousse Partners comprises experienced professionals with backgrounds in private equity, venture capital, and investment banking. Key individuals include Charles Heilbronn, the founder and chairman, and Arthur Heilbronn, a managing director. Michael Schultz serves as the Chief Financial Officer, while Megan Bethke is the Managing Director and Head of US/Europe Private Equity Funds. Paul Yun is another Managing Director, co-heading Private Equity and Venture Direct Investing.
