Boston backs its climate ambitions with real public infrastructure for startups.
Programs and agencies like MassCEC and Massachusetts Climatetech Studio offer grants, incentives, testing, and incubation to help climate companies get started and scale here.
MassCEC
MassCEC is Massachusetts's state clean-energy and climatetech agency and the anchor of non-dilutive founder funding, with Catalyst grants for early-stage prototypes and DICES grants for underrepresented or economically barriered founders, both paired with mentorship, market insight, and pitch coaching. Its wider stack adds demonstration and deployment grants, incubator funding, testing and demonstration assets, and tax incentives founders can access as they scale. It funds and enables rather than taking equity. Suits Massachusetts-based early-stage climate hardware founders needing non-dilutive prototype capital.
Massachusetts Climatetech Studio
The Massachusetts Climatetech Studio is a lab-to-market venture-creation program from MassCEC and FedTech that matches entrepreneurs with vetted IP from federal and university labs over an intensive cohort. Participants receive a stipend, pay nothing, give up no equity, and compete for a prize pool while accessing alumni services, entrepreneur-in-residence support, and workshops, culminating in a showcase. It is designed for people who want to build a company around existing lab IP rather than their own. Suits aspiring or serial entrepreneurs, technical or not, who want to found a climate company from lab IP.
Greentown Labs
Greentown's public-private programs are sponsored, equity-free accelerators for underrepresented founders and targeted challenges, led by its ACCEL program for BIPOC-led climatetech startups. ACCEL offers a non-dilutive grant, a curated curriculum, incubation at Greentown, and extensive mentorship, with global applications but in-person attendance. Other editions run corporate-sponsored challenges across areas like carbontech. Suits BIPOC and underrepresented climate founders wanting non-dilutive support plus Greentown's space and network.
MassChallenge
MassChallenge is a Boston-headquartered, zero-equity, no-fee accelerator running a roughly four-month cohort for large batches of startups, with mentorship from a deep bench, tailored curriculum, corporate-partner access, and workspace, ending in competition-based, non-dilutive cash awards. It is sector-agnostic with a defined climate challenge alongside health, fintech, and food. It takes no equity. Suits early-stage founders across sectors, including pre-revenue teams, who want a large network and prize capital without dilution.
