Where your climatetech startup can thrive
You’re the expert on your technology.
We’re the experts on scaling climatetech startups.
That’s a pretty great combination.
We know what climatetech and cleantech startups need to succeed because we transform their growth every day. From equipment to advice to workshops to introductions, we connect companies with the people and resources they need to thrive.
But we also know every startup is different, which means we’re continuously adapting to meet our members’ needs. Want to do something at Greentown that’s never been done before? Great—we’ll help you make it happen.
We have the data to prove this system works: 88 percent of the startups we’ve supported are still in business today.
Our members are innovating across the key greenhouse gas emitting sectors: electricity, transportation, buildings, manufacturing, and agriculture. What ties this community of entrepreneurs together is a common drive to tackle climate change with the technologies that will power our future—and an understanding that no one can do this alone.
The Greentown Community
What does community look like at Greentown Labs? It looks like helping a fellow member edit a grant proposal, borrowing another startup’s equipment, and sharing investor contacts. It looks like holding a door, striking up a conversation, and swapping ideas with your neighbors. It looks like a vibrant, humming workspace where people are collaborating to solve climate change.
We believe our community is our greatest resource. In fact, Greentown was founded in the spirit of community and collaboration. Our four founding startups worked alongside each other late into the night, providing emotional support and a lending hand. Nine years and 300+ startups later, many of our members still say the community is their favorite part of Greentown.

The Greentown Ecosystem: Corporates, Investors, and Others Who Can Help Your Company Grow
Greentown is all about forging connections. We need to work together to win the fight against climate change, and nowhere is the power of collaboration more apparent than at Greentown.
We’ve seen firsthand the magical outcomes of relationships between startups and corporates, inventors and manufacturers, entrepreneurs and fellow entrepreneurs. We aim to be the link between key partners, creating a leading community of climate champions that’s a nexus of collaboration, innovation, and change.
Access to Partners
Once you’re a member at Greentown, large corporations stop being enigmas and start being people. They’re the people who are hosting Lunch + Learns, holding office hours, and are really, really eager to meet you. Some of them are even working right next to you in the office. These connections lead to real results, from pilot projects to investments to R&D partnerships.
These partners also offer you the hardware, software, and professional services you need to succeed—think SOLIDWORKS, scientific articles, and prototyping equipment.
Investor Program
Our investor program’s mission is simple: to connect our startups with the capital they need to scale. From curating investor-startup matches to facilitating pitching practice and feedback, we’re committed to helping our startups navigate the fundraising process.
