Keenest, a Paris-based climate investment club, has surpassed €10 million in total funding for startups advancing the sustainable economy — achieving the milestone seven months ahead of schedule.
The platform has doubled its investment volume in just three months, following its earlier €5 million milestone first reported by EU-Startups.
“Individual savings are a massive lever for financing the sustainable economy,” said Jérémie Sicsic, CEO and co-founder of Keenest. “By investing directly in impact projects, every citizen becomes a driver of transition, helping build a greener, more resilient, and more sovereign economy.”
Powering the rise of community-driven climate finance
Founded in 2023 by Jérémie Sicsic and Renan Labrunie, the startup allows individuals to invest as little as €500 in vetted startups contributing to the ecological transition.
What began as a community of 300 investors has now grown to over 3,500 members, made up largely of individuals seeking transparent, high-impact alternatives to traditional investment funds.
Keenest’s portfolio includes a growing roster of climate and clean-tech startups such as Feedback, Sapiologie, Loewi, OpenClimat, Zilo Énergie, Kolverr, Arkeon Energy, Fenix Energy, Seaturns, Leviathan, Monomeris, and Veridian.
The platform’s model introduces “climate dividends” — returns linked to measurable CO₂ reductions. The greater the environmental impact, the higher the potential reward. Keenest targets average annual returns of around 20%, combining sustainability outcomes with investor performance.
“We’re redefining what responsible investing looks like — making it both accessible and rewarding,” added Sicsic. “Every euro invested should help decarbonize the economy, while offering fair returns to the people funding the transition.” 32,000 hours of hazardous labor for clients including BASF, BP, Dow Chemical, E.ON, Merck, Repsol, and Shell.

A growing movement in sustainable finance
Keenest’s rapid growth reflects the momentum across Europe’s impact investment ecosystem, where both retail and institutional investors are seeking transparency, accessibility, and measurable environmental results.
At the grassroots level, platforms like Portugal’s GoParity (€2.9M) have emerged to democratize access to impact finance. Meanwhile, larger institutional vehicles such as Norrsken’s €57M Evolve Fund, Suma Capital’s €210M SC Net Zero Ventures I, and Vireo Ventures’ €50M Electrification Fund I are scaling up their deployment of climate-focused capital.
The company bridges the gap between the two — bringing professional-grade impact investing to individuals who want to put their savings to work for both profit and purpose.
