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.
Now in its third year, this program combines acceleration with a curated curriculum, incubation through Greentown Labs membership, and extensive mentorship from Greentown and BGS’s networks of industry experts.
Greentown and BGS know the climatetech industry must change the status quo to equitably position founders from all backgrounds to lead startups that will address climate change, support the development of diverse workforces, and fiercely advocate for the deployment of clean technologies in historically underserved communities.
