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.”

Greentown Houston

“We had been looking for the best way to launch a team and hub and then learned about Greentown Labs, and it couldn’t have been any better. I’ve been around climatetech for more than 20 years, and there are a lot of incubators around the country, but I’ve never experienced one that was the ‘real deal’ like Greentown Houston is.”

Alexander von Welczeck

Founder + CEO, SkyH2O

“I’ve really enjoyed my time as a Greentown member. It’s been, first of all, a lot of fun—I really enjoy the people who are around us and the Greentown team. The lab is great for the stage we are now, which is single-product development. What I’ve found most useful is the amount of events. I always pop out and I see a bunch of people who I know, from the investor side of things or the customer side of things. I meet new people all the time here. It’s been a great experience, and we’re here every day at Greentown.”
