Family Office International SA
Family Office International SA was established in 2005 by Antoine Montandon. The office serves the Montandon family, whose wealth originated in Swiss watchmaking and industrial activities. Antoine Montandon holds an MBA from Bayes Business School, completed in the 2008/2009 class. The office allocates across private equity, hedge funds, real estate, and direct co-investments through SPVs. It also runs a fund-of-funds sleeve and maintains exposure to early-stage opportunities. Confirmed sector activity includes cannabis and psychedelics as well as data analytics. Allocations remain concentrated in Europe, with additional real-estate positions held globally. The firm lists 1,500 million USD under management. It participates in the Family Business Network and the Swiss Association of Asset Managers. Antoine Montandon is also linked to derpobus Sàrl through shared addresses and management roles. The structure centers on a single principal family with direct oversight by the founder, supplemented by external specialists for specific mandates rather than an integrated multi-family platform.
