Grantham Foundation

The Grantham Foundation for the Protection of the Environment is a leading force in impact investing, focusing heavily on climate change solutions and environmental protection. With a distinct venture capital arm, Neglected Climate Opportunities, the foundation zeroes in on high-potential, early-stage innovations that other investors often overlook. Their investments span across sectors like carbon capture, clean energy, and soil health, with a portfolio that includes cutting-edge startups such as Hazel Technologies, Summit Nanotech, and Ucaneo. These companies push boundaries in carbon offset, sustainable agriculture, and green tech. Geographically, the foundation targets a global scale, investing in ventures from the U.S., Australia, Canada, and Europe. Their strategy is clear: backing bold, speculative technologies in the environmental space, often providing first capital when conventional VCs shy away from the risk. Average check sizes vary depending on the startup’s maturity, but they are known for making both seed and early-stage investments. Led by Jeremy Grantham and Ramsay Ravenel, the team is based in Boston, but their reach extends worldwide. They remain actively engaged in venture capital markets, leveraging Grantham’s decades of expertise in market bubbles and green investments to identify impactful opportunities.
