🌏 Who are the Climate Tech Investors?

A new interactive Climate Capital Stack Map


We’ve said it before, and we’re saying it again: the climate capital stack is getting more sophisticated. Founders who can leverage the capital stack wield a major advantage — strategically, financially, and commercially. But let’s not get ahead of ourselves. First things first, who are these sophisticated investors, and how can founders navigate to a match? 

To support, we’ve been tracking the who’s who of the climate capital stack for the past few years. And now, we’re excited to announce the launch of our new tool to help founders and investors navigate the evolving landscape: an interactive climate capital stack market map.

The Climate Capital Stack tool makes exploring and understanding climate tech investors easier than ever before. Now, you can visualize who sits where across the stack, from early-stage venture capitalists to the heavy hitters in private equity and more. The clickable interface allows you to filter the investor list based on investor type and geographical location. You can also quickly search for specific investors to learn more about them.

We’ve refreshed our list and methodology for 2024, but those included remain the most active supporters of climate tech deals, quantitatively speaking. Whether you’re a founder looking for investors, an LP identifying potential fund investments, or even an investor searching for potential co-investors, this tool is for you. 

👉 See the The Climate Capital Stack market map here and use it to: 

  • Explore the Stack – Scan the climate investor universe to get a sense of who’s active across different layers. Get an overview of investors from the list, or dive deeper by clicking their logos.
  • Narrow your focus – Use the filters at the top to narrow the landscape. Looking for Early-stage investors based in Europe? Just filter the selection and you’ve got it.
  • Make your case – Since we started doing the Climate Capital Stack, we’ve seen it appear in decks across the globe. Now, whether you want to show the whole Stack, or just a part of the landscape, just click ‘Download’ at the bottom right and pop the image into your slides.
