ACCEL, an accelerator from Greentown Labs and Browning the Green Space (BGS), is bolstering BIPOC-led startups as they develop critical climatetech solutions by offering access to funding, networking connections, resources, and opportunities that structural inequities put out of reach.

This year-long program combines acceleration with a curated curriculum, incubation through a Greentown membership, and extensive mentorship from Greentown and BGS’s networks of industry experts.
