ACCEL is a year-long climatetech accelerator for BIPOC and other underrepresented founders, run jointly by Greentown Labs and Browning the Green Space out of Somerville, MA and Houston, TX. In its most recent completed cycle (Year 3, cohort announced February 2025), startups received a non-dilutive grant of up to $25,000 plus a year of Greentown Labs incubator membership, curriculum, and mentorship, with no equity taken. As of July 2026 no new application cycle has been announced, so current-cycle terms are not published.
Who this is actually for
Early-stage and pre-seed climatetech startups led by BIPOC and other underrepresented founders who can participate through Greentown's Somerville, MA or Houston, TX locations. Because no new cycle is currently announced, treat this as a program to watch rather than one to plan an application around today.
