Accelerating the Clean Energy Transition in the Energy Capital of the World
Houston is an energy hub unlike any other that’s capable of leading the way in renewable energy and the decarbonization of our planet—something we see happening every day in our community of climatetech startups.
Our 30,000-square-foot incubator, located in Houston’s Ion Innovation District, is home to 100+ member companies and offers prototyping lab, office, and community and event space.

“Greentown is in the energy capital of the world and gives unparalleled access to major industry players, other founders I can talk to, and resources including introducing me to investors. Every month, there’s an event going on that really helps me connect with all the players in the ecosystem. We have had our most rapid growth after coming to Houston and joining Greentown Labs, in terms of partnership, in terms of deployment. Greentown has supported us in a very important way.”
