Advancing Climatetech and Clean Energy Leaders Program (ACCEL)

The year-long program combines acceleration with a curated curriculum, incubation at Greentown, and extensive mentorship from Greentown and Browning the Green Space (BGS)'s networks of industry experts. Selected startups participate in trainings led by VentureWell covering customer discovery, pitch decks, financial models, and fundraising. Additional workshops span product development, market strategy, capital raising, legal guidance, and team building. Participants gain valuable mentorship and receive fundraising and investment support, including pitch-deck development and investor introductions. The program also provides desk space and membership within Greentown, granting access to in-kind resources like software and legal support, corporate partners, and community resources. Participants also receive BGS membership to connect with clean-energy sector practitioners.
