Greentown Houston

Greentown Boston
The climate challenge has never been a single problem with a single solution: it runs through every system that shapes how we live.
Meeting this moment requires transformative innovation across all of our world’s industrial systems: how we power our lives, move through cities, build and manufacture goods, grow and distribute food, and manage the natural resources the whole planet depends on.
And at Greentown, our bet is on the entrepreneur.
But no founder succeeds alone: breakthroughs scale when entire ecosystems of innovators, corporates, investors, researchers, philanthropists, and policymakers move together.
That’s why once a year, we open our incubators and invite you to step inside our labs to meet our 260+ climatetech startups, hear perspectives from industry leaders, and forge connections with changemakers across the ecosystem.
This is where the right people find each other. We hope you’ll be one of them!



Greentown members and partners receive complimentary access to the event. For instructions on how to register, please reach out to your main point of contact at Greentown.
At Greentown Labs, we believe the urgent need to address climate change must be inclusive of all voices. If you or your organization is interested in attending the Climatetech Summit but do not have the financial means to purchase a ticket, please contact us to learn about opportunities to engage.
What Past Attendees Say About Climatetech Summit
“The mood was exuberant and the technologies were exciting at the #ClimatetechSummit Boston with Greentown Labs today. It was inspiring to hear of so many new technologies that can help us at GE Vernova and our energy transition partners to bridge the gap and solve the energy demands coming at us in the next 20 years!”
“The lineup today is on point, the pitches give me hope about the next generation of technology, and the focus on radical collaboration and strategy for public-private partnership to drive policy and creative funding approaches are exactly what we need to get more people talking about the art of the possible with acceleration of climate solutions.”
“From chemical manufacturing to data-center energy management to speeding up construction timelines — the innovations on display at this year’s #ClimatetechSummit Houston were very impressive. Even in a shifting market, it’s clear there’s still a huge need for solutions that cut costs, save time, boost resiliency, and lower emissions all at once.
Huge thanks to all the investors, founders, partners, and experts who made it happen! Loved hearing from such inspiring speakers, discovering 35+ amazing startups, and connecting with so many great people.”
