[ 03 ]Who We Are

Greentown is a 501(c)(3) nonprofit helping climate entrepreneurs build faster.

The way the world makes energy, materials, and food is changing — and the next decade will decide whether that change makes life better: more energy with fewer emissions, more industry with cleaner air, more good jobs.

That future comes from entrepreneurs — the heroes who turn ideas into real products, real companies, and the jobs of the future. And the ones who make it are the ones with a community behind them.

For 15 years, Greentown has been that community — leaning in with the space, the people, the funding, and the first customers they need. Get behind the entrepreneurs building our future.

[ 04 ]By The Numbers
