## About

Clear Eight Group was established in 2009 by Mark Antony Mathysen-Gerst and Bernard Frédéric Girardet. The founders built the firm to provide wealth-management and direct-investment services to international entrepreneurial families. Operations are centred in the Geneva area with headquarters in Thonex. The firm deploys capital through direct co-investments and SPVs in private equity and real estate. Asset classes include public-market holdings, private-equity positions and residential developments. Confirmed projects comprise the Cologny Luxury Mansions Project, Vandoeuvres Residential Project, Corsier Residential Development and Anières Villa Projects, all located in the Geneva region of Switzerland. Additional exposure includes Platinum Group Metals. Geographic focus remains Europe, with all documented activity inside Switzerland. Team size and total deployment figures are not publicly stated. The firm maintains separate legal entities for capital, property and travel services. Roberto Castro advised on the Podium Minerals transaction. No dated operational events from the last twenty-four months appear in available records. Clear Eight Group structures its activities through three distinct entities that separate investment management, real-estate execution and concierge services. This separation allows dedicated teams to handle tax optimisation and property structuring without commingling mandates across the multi-family client base.
