Meridiam

About

Meridiam is a French management company specializing in sustainable infrastructure, founded in 2005 by Thierry Déau: over $23 billion under management, 130 assets across three continents, a mission-driven company certified B Corp. On the company side, the entry point is the Green Impact Growth Fund (GIGF), a growth capital fund launched in 2021 with a target of €300 million (over €150 million at the first closing, with the EIB among the subscribers), led by Eric Rey. It invests checks from €5 to €30 million, both minority and majority, in European SMEs growing over 15% per year and that are profitable or will be within 12 to 24 months. Portfolio: Certideal, Shopopop, PopChef, ESG Book, Okamac, Exoès, Oxand, iwell, Blyyd, and Chargepoly. The group's infrastructure funds also invest in energy transition companies: Voltalis, Verkor, Allego. For a founder in the ecological transition (low carbon, circular economy, clean mobility, sustainable cities, food) already close to profitability, it's a fund capable of leading a round of over €20 million alone (Chargepoly, €23 million in 2026) or taking the majority (Oxand, 2025).
