What The Clean Fight does

The Clean Fight is a not-for-profit climate-tech accelerator founded in 2020 and headquartered in New York, operating as a chapter of the international nonprofit New Energy Nexus. Its mission is to accelerate the adoption of proven climate solutions by bridging the gap between initial deployment and broad market adoption for growth-stage climate tech companies. The organization runs cohort-based accelerator programs focused on four core verticals: building decarbonization (including the $10M Empire Technology Prize for tall buildings), energy storage deployment (including the Energy Storage Capital Challenge), food services decarbonization, and affordable housing decarbonization for low- and moderate-income communities.

The Clean Fight does not develop proprietary technology itself; rather, it operates as an ecosystem orchestration platform. Its core offering is the Deployment Accelerator, which provides high-touch customer and capital partner matchmaking, tailored technical assistance, structured summits, and non-dilutive grant funding of up to $250,000 per company (requiring a 2:1 private match). Since 2020, it has supported 70 companies, administered $5.4M in grants with a 5:1 private-to-public match ratio, facilitated 5,000+ deployments in New York State, helped portfolio companies raise $784M in follow-on capital, and created 945 new jobs. Supporting programs include the International Landing Pad for European entrants, the Affordable Housing Cohort, and the national Deployment Grant Fund launched in 2025.

The business model is grant-funded rather than revenue-generating in a traditional sense. The Clean Fight is sustained by awards from government entities (NYSERDA, NYC Economic Development Corporation, U.S. Department of Energy, U.S. Economic Development Administration) and philanthropic foundations (Rockefeller Foundation, Builders Vision, Breakthrough Energy). It takes no equity in cohort companies and charges no fees to applicants. Revenue derives from program administration budgets associated with each accelerator cohort and prize program. The customer base spans three groups: growth-stage climate tech companies (cohort applicants), enterprise customer and capital partners (real estate firms, utilities, construction companies, VCs, green banks), and government/philanthropic funders.
