## About

Xelis Family Office was established in 2005 by Véronique Aubin. The firm operates as an independent multi-family office serving entrepreneurial families with personal and professional asset oversight. Services cover patrimonial structuring, investor accompaniment and daily administration including tax filings, personnel management and cash-flow forecasting. Asset-class exposure centers on ESG mandates alongside private debt and direct investments in innovative companies. Geographic reach stays within France and extends to international holdings through partner banks and advisors. Confirmed operational updates include a December 2025 profile of Aubin by Décideurs naming her among wealth-management pioneers. The firm lists eight named family officers and maintains a single headquarters in central Paris. No additional offices, philanthropic vehicles or club memberships appear in public materials. All reporting tools run on a self-hosted French cloud infrastructure. Independence from product providers constitutes the core structural feature: compensation derives solely from client fees, removing incentives tied to asset gathering or proprietary funds.
