## About

SGFC was established in 1987 by Thierry Roussel. The firm stewards capital originating from the Roussel Uclaf pharmaceutical business. It functions as the dedicated vehicle for the family's multi-generational holdings. The office executes direct co-investments, SPVs, hedge fund commitments, private equity and secondaries. Confirmed positions include real estate assets in France, Spain and Switzerland plus exposure through E8 Partners and Hedgeblock AG. Geographic reach centers on Europe with additional allocations in Asia and Africa. Erik Roussel and Johanna Roussel serve as partners and contribute to real estate and technology decisions. SGFC employs a compact team led by David Arnaud as Head of Single Family Office. The firm maintains its headquarters at Chemin du Joran 6A in Nyon. Adjacent holdings include the Roussel Family Chateau in Villeny and a 64.6m project by Marcelo Penna. No operational events from the last 24 months appear in available records. SGFC operates through a hybrid structure that combines internal fiduciary services with external club memberships. Hedgeblock AG, an SGFC entity, belongs to the VQF SRO. Erik Roussel sits on the board of the PropTech Association. This setup separates family governance from third-party manager relationships.
