The sheer concentration of capital, talent, and corporate partners creates a strong ecosystem for climate innovation.

But among the many investors calling NYC home, which ones are actually backing Climate Deep Tech?

To help navigate the landscape, we’ve compiled a fresh list of 80 NYC-based investors actively writing checks into ClimateTech.

The criteria: 

  • At least one senior (Associate or Partner) full-time team member based in New York.

  • Holds at least one direct investment in ClimateTech or publicly lists Climate Tech as one of their core investment areas

  • Still open and active.

Think you (or someone you know) should be on the list too? Drop us a note at [email protected] to add them in.
