Xénia Gestion Privée
Xénia Gestion Privée was established in 2010 by Matthieu Dumas and Antoine Debois-Frogé, two wealth-management practitioners who pooled their corporate-finance expertise to serve business-owning families like their own. Dumas sits on the Supervisory Board of Hermès International, and Xénia’s investment activity is closely aligned with Krefeld Invest, the consolidated family office for Hermès heirs that is led by fellow descendant Charles-Éric Bauer. The multi-family office structures portfolios across private equity, real estate and listed securities, with a pronounced tilt toward operating businesses anchored in French heritage. Confirmed positions include the Boves real estate portfolio, a mixed-use holding in Boves, France, and La Cité de la Cosmétique, a commercial property at 2 rue Odette Jasse in Marseille. Hospitality exposure runs through the Hôtel de la Couronne in Chamonix. Geography concentrates on France and continental Europe. Xénia’s co-investment circle links directly to the Hermès family’s consolidated investment vehicle, giving the firm unusual access to proprietary deal flow in French luxury, real estate and mid-market corporate carve-outs. Charles-Éric Bauer’s firm Hem-Fi Conseil provides parallel advisory capacity, reinforcing the governance architecture that keeps investment decisions inside the family network. The firm operates additional property holdings in Boves and Chamonix, but does not publicly disclose total assets under management or a staff headcount. The structural differentiator is governance by descent: investment authority sits with Matthieu Dumas, whose dual role as Hermès supervisory board member and MFO chairman creates a direct pipeline between the family’s corporate wealth and its private investment deployment — a setup that blurs the line between family office, holding company and deal club more than a conventional multi-family office would.
