Sagis Asset Management Family Office

Sagis Asset Management Family Office traces its roots to 2013 when Arnaud Gosset-Grainville combined his existing advisory practice with Cardinale West. The resulting multi-family office serves families and foundations primarily from France while extending reach into other European markets. Its structure preserves the original advisory focus on generational wealth planning alongside investment execution. The firm allocates across private equity, real estate, and select venture opportunities. It commits to funds such as GENEO Capital Entrepreneur II and joins direct transactions including the 2023 acquisition of Famility and the 2023 owner buy-out of Transports Veynat alongside GENEO and Bpifrance. Additional positions include YesWeHack, Skeepers, I-TRACING and Valgo. Activity centers on Europe with secondary exposure to North America. Assets under management stand at €2.3 billion according to internal records. The team operates from a single Paris office and maintains dedicated vehicles such as S Tempo DNCA and S Tempo Fidelity. In November 2023 Sagis completed the Famility acquisition, a step intended to increase scale and client breadth. It also holds membership in the Association Française du Family Office. Sagis operates with an approved AMF structure that permits creation of reserved funds for specific families. This regulatory posture enables customized mandates while the firm retains a minority shareholder in Siparex to support inorganic growth.
