Famility
Famility was established in 2007 by Jean-Yves de Louvigny. He previously worked as a private banking executive at Credit Suisse. The firm centralizes wealth, tax and succession services for entrepreneurial families. Famility advises on asset allocation, legal structuring and estate planning. It negotiates with banks and insurers on behalf of clients. The office operates across Europe. Confirmed relationships include co-investor Siparex and partner Sagis, which completed the acquisition in December 2025. The firm maintains membership in ANACOFI. It holds an AMF license for portfolio management through its Sagis parent. No additional offices are disclosed. The December 2025 acquisition by Sagis integrated Famility into a larger wealth platform. Famility operates as a regulated multi-family office under Sagis ownership. This structure provides AMF authorization to create reserved funds for multiple investors while maintaining focus on family governance and succession.
