If you’re building a company to solve the world’s hardest climate and energy challenges, you shouldn’t have to do it alone. Greentown is where founders find the labs, the community, and the first customers to move faster — and where a win for one startup is a win for all of us.
Climate & Energy Ambition
You’re building technology that moves the world forward — more energy, fewer emissions, cleaner industry, or smarter use of resources. If your work makes the planet more livable and the economy stronger, you belong here.
Ready to Build
Most of our members are moving from prototype toward first customers — the hardest stretch of any hardware or deep-tech journey. We support founders from early R&D through commercialization, and we’re built for the companies pushing to get there faster.
Community Fit
Innovation is a team sport. The founders who thrive here show up for each other — sharing equipment tips, warm intros, hard-won lessons, and celebrations. Bring your ambition and your generosity; you’ll get both back many times over.
