## About

Joakim D. Lehmkuhl and Gilles Lambotte established Octogone Family Office SA in 1995. The firm began as an independent asset manager and later passed through ownership by Focus Financial Partners from 2022 to 2026 before a management buy-out. Octogone deploys capital through direct co-investments, SPVs, hedge funds and private equity. It maintains exposure to real estate via Octogone Real Estate Fund I LLC, which targets mixed-use assets in Europe, the United States and Latin America. Additional holdings include the Octogone Partners Fund LP, a digital asset portfolio, blockchain private equity positions and gold and energy exposure. The firm restricts most activity to early-stage opportunities and maintains offices or mandates that reach the Middle East and Central Asia. The firm employs an undisclosed number of professionals at its Geneva headquarters. It also operates Octogone Art Collection Services and maintains membership in Citywire Top 50 Independent Asset Managers. In 2026 Hareb Al Darmaki supported the management buy-out that returned control to the founding team after the Focus Financial Partners period. Octogone structures its platform around a combination of regulated asset management and dedicated vehicles for passion assets and digital holdings. This architecture allows separate treatment of art, real estate and blockchain exposure while preserving a single reporting layer for client families.
