The Challenge
Growth-stage climatetech startups face distinct challenges, including significant capital needs, regulatory complexity, and customer adoption barriers, as they scale from pilot projects to commercial deployments. Sustained support is critical—without it, startups struggle to penetrate markets and build the financial momentum required for lasting success.
About CriticalMass
CriticalMass, MassCEC’s latest growth-stage Tech-to-Market program provides up to $1,000,000 in grant funding, specialized services, and partner matchmaking to startup applicants with strong track records of early-stage commercialization and successful demonstration projects. Successful applicants will propose commercial deployment projects that address important decarbonization challenges within MassCEC's four focus areas, help to grow the state’s clean energy economy, and contribute to Massachusetts’ continued clean energy leadership.
Who's Eligible
Startup companies interested in deploying their TRL 8+ climatetech Innovations in Massachusetts are invited to apply to CriticalMass.
