ClimateHaven

What ClimateHaven does

ClimateHaven is a 501(c)(3) nonprofit climate tech incubator founded in 2023 and headquartered at 770 Chapel Street in New Haven, Connecticut, two floors above the MakeHaven makerspace and within walking distance of Yale University. It operates an integrated platform that combines 18,000 sq ft of physical workspace and prototyping infrastructure, sprint-based operator-led programming, an Expert Advisory Network, and ecosystem partnerships to support early-stage (pre-seed through Series A) climate technology founders across sectors including carbon removal, water treatment, built environment, energy, transportation, and agriculture. Its core product offerings are the member-only Incubator Program, the Startup Playbook knowledge resource authored by founder Ryan Dings, Cowork + Labs (which bundles free MakeHaven membership for 3D printers, laser cutters, and CNC access), the Water Innovation Hub (a 2025-launched vertical that brokers water-tech pilots with utilities, corporates, and academics), and the ReGen Accelerator (a 2024-launched partnership with Kaplak running two annual tracks for startups and scaleups).

The business model is donation- and grant-led rather than fee-led. The majority of revenue is generated through tax-deductible donations from supporters (EIN 92-0306841), supplemented by federal and state grants — most notably a $1M+ award from the U.S. Department of Energy's Office of Technology Transitions and $500,000 in Congressionally Directed Spending, both secured in December 2024 with support from Sen. Blumenthal and Rep. DeLauro — and a secondary stream of subscription membership fees for floating desks, dedicated desks, and private offices (pricing not publicly disclosed). Distribution and customer acquisition run through a community-led GTM: direct membership applications via a web portal, ReGen Accelerator cohort recruitment via Kaplak's global networks, the Water Innovation Hub's annual Innovation Challenge (global applicant pool), and recurring ecosystem events such as Green Drinks and the Yale Clean Energy Conference. As of November 2023, the incubator opened with 17 enrolled startups; by 2024 ReGen supported 20 additional companies across two program tracks, and in 2025–2026 the Water Innovation Hub added Xylem, South Central Connecticut Regional Water Authority, and Continua as partners to operationalize a B2G/B2B pilot pathway.

Broad incumbents

• MaRS Discovery District: MaRS is one of North America's largest urban innovation hubs in Toronto, supporting a broad range of startups (not just climate) with workspace, advisory, and program services. Comparable incubator-plus-programming model but at much larger scale and broader scope.

Regional players

• NYSERDA ClimateTech Programs: NYSERDA runs state-funded climate-tech innovation programs and NY Prize competitions for clean-energy startups in New York. Comparable state-level public funding and accelerator programs, but serving New York rather than Connecticut/Northeast.
• Station F: Station F is the world's largest startup campus in Paris, hosting climate-tech and impact programs with corporate partners. Comparable physical-anchor incubator model, but at much larger scale and non-overlapping geography.
