Greentown Labs

Accelerator · Boston

About

Greentown Labs is a Boston-based startup accelerator that supports climate innovation and clean technology. Originating its event programming in 2026, the organization serves as an anchor for founders and emerging ventures developing climate solutions. Operating out of major industrial hubs, it bridges early-stage entrepreneurial support with regional industry networks to advance the development and deployment of commercial climatetech solutions.

What they run

The accelerator has seven total gatherings across Boston and Houston, encompassing past summits, meetups, a mixer, and a pitch night. Its recurring flagship programming includes the Boston Climatetech Summit, which has seen two editions. Moving into future engagements, Greentown Labs has scheduled the Carbon to Value Initiative Year 6 Kickoff meetup in Houston for December 3, 2026.

Who attends

Events draw a focused crowd of climatetech entrepreneurs, startup teams, and regional climate innovation professionals. Meetups, pitch nights, and mixers attract early-stage venture leaders seeking peer collaboration and pitch opportunities, while the dedicated climate summits bring together ecosystem stakeholders, technical specialists, and partners active across the energy transition and carbon-to-value sectors in Massachusetts and Texas.
