25 Climate Tech VCs Backing Pre-Revenue Startups
By TurboFund Research Team
Get the list every week
New curated investor lists by sector, stage, and geography.
If you're building in Clean Energy & Climate and raising capital, the first question isn't whether VCs are interested. It's which ones actually have a thesis in your space. Most "top investor" lists recycle the same ten names. This one is pulled directly from TurboFund's database of 250,000+ investor profiles, filtered for verified Clean Energy & Climate investment activity.
Every fund below has demonstrated a real commitment to Clean Energy & Climate. Not a single portfolio company that happens to touch the space, but a genuine pattern of deployment. I Squared Capital, Buoyant Ventures, and Decarbonization Partners are among the most active, but this list goes deeper than the obvious names. The goal is to surface funds you might not find on the first page of Google but that are writing checks right now.
We're not ranking by brand recognition or AUM. These funds were sorted by Crunchbase rank and filtered by sector focus, a proxy for actual investment velocity and portfolio relevance. If a fund is on this list, they've put real capital into Clean Energy & Climate companies, not just talked about it on a panel.
Study the portfolios before you reach out. Identify where your company fits within their existing bets, and come in with a point of view on why what you're building is different from what they've already backed.
This list covers 25 funds. The full TurboFund database has thousands more, filterable by check size, stage, geography, and portfolio. There's a 14-day free trial, no credit card required.
