Thomas Dubourdieu

Thomas Dubourdieu is a Bordeaux-based private-equity investor who leads the Bordeaux office of Ouest Croissance Gestion. He began his career in strategy consulting at Kurt Salmon, then moved into financial due diligence within EY's Transaction Services practice, before transitioning into private equity by joining Arkéa Capital (the PE arm of Crédit Mutuel Arkéa) in Bordeaux in 2019 as a chargé d'affaires / investment professional supporting SME and mid-market growth in the region.

In 2023 he was recruited by Ouest Croissance to open and run its Bordeaux presence in Gironde, joining as Directeur Associé. Reporting/press coverage at the time noted the firm was strengthening its Nouvelle-Aquitaine footprint with a dedicated local team (alongside long-time investor Julien Arnaudeau) and new offices in central Bordeaux. His profile blends three complementary skill sets: strategy consulting, transaction-services/financial due diligence, and hands-on minority equity investing.

On education, Dubourdieu studied at Paris School of Business and holds the DSCG (French higher accounting diploma) plus a Mastère Spécialisé "Technologie et Management" (Advanced Master in Technology & Management) associated with CentraleSupélec / École Centrale Paris.

Ouest Croissance, founded in 1987 and owned by three Banque Populaire regional banks, manages on the order of €200M and has backed more than 500 regional SMEs across the western arc of France. It positions itself as a responsible, long-horizon minority investor.

• Invests in profitable, established SMEs and mid-caps (usually €10M–€150M revenue), not startups — the "angel/seed" label from aggregators does not reflect his actual mandate.
• Two core strategies: capital développement (financing organic and external growth) and capital transmission (management buyouts / ownership succession), always as a minority shareholder.
• Equity tickets roughly €1M–€20M (with a newer fund concentrating on €3M–€13M deals).
• Generalist / multi-sector, with regional emphasis on digital, aerospace, energy and mobility ecosystems around Bordeaux.
• Regional, relationship-driven approach: proximity, local presence, and long-term support through development, structuring, international expansion and eventual transmission — with stated attention to sustainability and digitalization.
