What Ouest Croissance does

Ouest Croissance Gestion, operating as Ouest Croissance, is a Nantes-headquartered private equity firm specialized in growth capital and business transmission for French SMEs and mid-market companies (ETIs) in Western France. Established approximately 38 years ago, the firm operates under AMF regulatory accreditation GP-20230017, obtained on August 8, 2023, and supports companies across eleven sectors including aerospace-defense, media-telecom, retail, tourism, education, optical, composites, leisure vehicles, and industrial manufacturing.

The firm offers two core investment services. Development capital (Capital Investissement - Développement) provides growth funding and strategic resources for SMEs entering new growth phases, while Transmission capital (Capital Investissement - Transmission) facilitates ownership transitions through management buyouts (MBO), management buy-ins (MBI), and generational transfers. The firm manages multiple investment vehicles through a Société par Actions Simplifiée (SAS) structure with a share capital of €599,634, and maintains an active portfolio of approximately 100 companies as of 2026. Notable portfolio holdings include SIDAMO (professional tools, MBO 2017), Otonomy Aviation (aerospace supplier), AMP Visual TV (media production), Edgard Opticiens (optical retail), Easy Cash (second-hand retail), DEMGY (composites, from €27M to €130M revenue), Les Vedettes de Paris (cruise tourism), Glénan Concept Cars, and Noschool (education).

Ouest Croissance generates revenue through capital gains on portfolio exits and management fees from its investment vehicles. The firm employs 17 experienced professionals across four offices in Nantes (headquarters at 1 rue Marie Anne du Boccage), Paris, Bordeaux, and Rennes, with a direct enterprise sales model targeting business owners and management teams. The firm has integrated ESG (Environmental, Social, Governance) practices across its investment operations under a dedicated ESG Manager and routinely co-invests alongside BPI France, Société Générale Capital Partenaires, Turenne Capital, Unexo, Carvest, NCI, and Océan Participations. Its go-to-market relies on direct relationships, regional industry events, referral networks, LinkedIn presence, and an investor newsletter rather than broad marketing campaigns.
