ClimateTech Fund

ClimateTech Fund

Invests in Connecticut climate-tech businesses from seed through growth stages in clean energy and mobility sectors.

The ClimateTech Fund is a $100 million equity investment vehicle managed by Connecticut Innovations, Connecticut's quasi-public venture authority, targeting companies working on climate mitigation, adaptation, and environmental protection. The fund plans to invest in 15 to 25 companies over a 10- to 15-year investment period across verticals including energy, mobility, circular economy, water, food and agriculture, carbon removal, advanced materials, and the built environment. Instrument is equity — CI participates via priced rounds, convertible notes, and SAFEs, with initial investments ranging from $150,000 to $2 million per company in a given round, capped at $20 million total per company across the fund's life.

Co-investment is required: Connecticut Innovations aims to be no more than one-third of any syndicated round, so applicants must have or secure outside co-investors. Company stage is flexible, spanning proof-of-concept, seed, Series A, and Series B/C, as well as fund-of-funds opportunities for venture firms. Primary eligibility requires a majority Connecticut employee presence or a firm commitment to create Connecticut jobs; international companies must agree to establish a US headquarters in Connecticut.

Applications are accepted on a rolling basis with no deadlines. Founders submit a pitch deck via CI's online portal. The fund is managed by Konstantine, a managing director at CI focused on climate and adaptation technology. Portfolio companies include AmpUp, CarbonBuilt, Cambium Carbon, Budderfly, and Oxylus Energy, illustrating the range of stage and sub-sector the fund has backed. Personal guarantees are not required.
