What Demeter does

Demeter is a Paris-headquartered private investment management firm specializing exclusively in ecological and energy transition, operating across the full private equity spectrum from venture capital and growth equity through buyout, infrastructure, mezzanine, and private debt. Founded in 2003, the firm manages €3 billion in assets under management raised from institutional investors, corporations, and family offices, and has supported more than 450 startups, SMEs, and projects over 20+ years of activity. Following the 2023 merger of Demeter Investment Managers with Cerea Partners, the combined platform operates as Demea Invest with two divisions: Demea Sustainable Investment (ecological and energy transition) and Demea Agro (agrifood).

The firm operates specialized fund vehicles covering thematic areas including urban ecological transition (Paris Fonds Vert, targeting €200M), sustainable viticulture (VitiRev Innovation), sustainable industry (FAIM), circular economy (Circular Innovation Fund), climate infrastructure (Climate Infrastructure Fund), and innovation for adaptation and mitigation (IAM). Demeter has developed a proprietary ESG and territorial impact measurement methodology in partnership with Carbone 4, which tracked 7.6 million tonnes of CO2 emissions avoided and 37 TWh of energy savings across the portfolio in 2022. Multiple funds carry the most stringent EU SFDR Article 9 classification, and the firm holds the TEEC label (audited by EY) on its Paris Green Fund, AMF approval (GP 05 000027), and is a signatory to PRI, CDP, iC20, and The Shift Project.

Demeter generates revenue through management fees on its €3 billion AUM and carried interest on successful exits, with remuneration partially indexed to ESG performance objectives. The firm employs 70 professionals of 6 nationalities across six offices in Paris, Lyon, Bordeaux, Düsseldorf, Madrid, and Montréal. Its customer base spans two-sided: LPs (institutional investors, corporations, family offices) on the fundraising side, and portfolio companies (startups, SMEs, and ETIs in agriculture, agrifood, energy, environment, mobility, and green industry) on the deployment side. Notable portfolio companies include Phagos (€25M Series A), Opendatasoft (€21M), Optimum Automotive (€14M), and Courb (€3.7M). The firm was named European Investor of the Year 2022 by Cleantech Group.
