## About

Partners Advisers was established in 1998 by a family group that had begun hedge fund investing in the mid-1980s. Luc Estenne, previously a proprietary trader at Bank Brussels Lambert in Brussels and New York, set up the firm as a family office. A second family group joined the capital base in 2013, shifting the entity toward a professional multi-family platform while retaining family ownership. The firm deploys capital through a multi-manager framework that includes long-only public equity funds, hedge funds, private equity and private credit funds, plus selective direct private equity and credit investments. It maintains a bottom-up portfolio construction process combined with macro overlays. Allocations target idiosyncratic returns with lower market correlation. The geographic focus remains Europe. No specific portfolio company names appear in public materials. The firm employs a compact team of investment, research and operations professionals. Timothée Henry has served as Chief Operating Officer and Risk Officer since 2004. Additional offices are not disclosed. Mathieu Woifflard joined in 2025 as Investment Manager and Senior Research Analyst. No philanthropic vehicles or club memberships beyond the FINMA authorization are listed. Partners Advisers maintains an independent board and segregates investment, risk and compliance functions under Swiss regulatory oversight. Co-investors, shareholders and the investment team participate in the same program, creating direct alignment without traditional client relationships.
