Nantes-based Colbert Groupe has acquired a 51% majority stake in IDP Stratégie from its founder, Catherine Bizé. The transaction, initiated during a seminar organized by the InComon group, marks Colbert’s strategic entry into the Paris (Île-de-France) market. The acquisition was partially financed through bank debt, valuing IDP Stratégie between €1 million and €1.5 million. As part of the deal, Catherine Bizé has reinvested a portion of her proceeds into Colbert Groupe, joining the 14 other associate-managers at the group level. The strategic rationale for the acquisition is twofold: it provides Colbert Groupe with a permanent physical office in the capital to serve growing demand, and it immediately adds €85 million in Assets under Advisement (AuA) to the group’s "Patrimoine Finance" pole. This division now represents ~30 professionals and €5 million in revenue. For IDP Stratégie, the merger allows the team to deploy Colbert's wider range of specialized services (Real Estate, Retirement, Life Insurance) to its existing Parisian client base. This deal follows Colbert's strategy of disciplined external growth, bringing its total consolidated group revenue to €16 million in 2025.
