Amplegest

Amplegest is the family office of France's Cyrus Group, investing in private credit, real estate, and infrastructure across Europe.

Amplegest

Amplegest is the family office arm of the Cyrus Group, a French financial services group founded by Arnaud de Langautier. Its wealth originates from Cyrus Group's asset management and advisory operations, which includes a minority stake held by Bridgepoint and a later acquisition by PAI Partners (Altss research). Amplegest's investment strategy spans private credit, real estate, infrastructure, and energy transition, with direct co-investments alongside external managers. The family office holds a confirmed position in Eternam Real Estate Projects, a mixed-use development in Paris. Its geographic footprint is centered on France and Western Europe. The team size and total assets under management are not publicly disclosed. The office signed the Principles for Responsible Investment (PRI) in 2021 and is a participant in the Carbon Disclosure Project (CDP). Amplegest also maintains philanthropic commitments to 1001fontaines and Espérance banlieues. A structural differentiator is Amplegest's direct lineage within Cyrus Group's broader financial ecosystem — combining proprietary deal flow from the group's advisory business with co-investment access through relationships like PAI Partners. This hybrid sourcing model allows the family office to anchor transactions that originate within Cyrus Group while participating in third-party managed funds.
