Cohaesia Family Office

Cohaesia Family Office was established in 2010 by Jean-Baptiste de Belot, Agnès Guittard and Stéphanie Zimmermann. The three founders combined prior experience in private banking, legal practice and financial services. The firm addresses multiple client families rather than a single wealth source. It allocates across private equity, real estate and digital assets. Mandates cover early-stage and growth opportunities inside Europe. Vehicles include direct co-investments, SPVs and fund-of-funds commitments. The operating team remains the three founding principals. All activity is conducted from the Boulogne headquarters. Cohaesia maintains membership in the Association Française du Family Office.
