TIME just recognized our accelerator as a national leader! 

Each year, we enable 30-50 cleantech startups to save 2.5 years as they progress from lab to impact. Funding enables us to: 
- manage hundreds of volunteer mentors, coaches, judges and speakers
- strengthen relationships with hundreds of partners (accelerators, incubators, and universities)
- run in-person events such as the 2-day Academy at the beginning of the accelerator (May 28-29, 2026, at Dock 72 in Brooklyn, NY) and the Finals and Global Forum (October 21-22 in Boston, culminating in a Showcase and Awards Celebration at Greentown Labs in Somerville, MA)
- award cash prizes ($77,500 in 2026)
