Connecticut Innovations ClimateTech Fund
Industry-Specific · Connecticut Innovations · CT
The Connecticut Innovations ClimateTech Fund is a $100 million state investment fund for climate-focused companies headquartered in or growing jobs in Connecticut, offering equity or blended-debt investments of $150,000 to $2 million rather than a traditional cash grant.
The Connecticut Innovations ClimateTech Fund is a $100 million investment fund run by Connecticut Innovations, the state's strategic venture capital arm. It is aimed at companies working on climate mitigation, adaptation, or environmental protection, and it invests in businesses from the proof-of-concept stage through Series B or C rounds.
Unlike a traditional grant, this program provides capital through equity investments, convertible notes, SAFEs, and blended debt structures. Award amounts noted range from $150,000 to $2 million per investment round, though this is investment capital rather than a cash grant that requires no repayment or ownership stake.
To qualify, a company generally needs to be headquartered in Connecticut or committed to growing jobs within the state, and its work should be tied to climate-related outcomes—whether that's reducing emissions, helping communities adapt to climate impacts, or protecting the environment in some measurable way.
For a small business owner in the climate technology space, this fund could be a meaningful source of growth capital, particularly if traditional bank financing or early-stage venture funding is hard to access. However, because Connecticut Innovations takes an equity or blended-debt position rather than giving away non-dilutive grant dollars, applicants should understand that this arrangement typically involves giving up some ownership or agreeing to repayment terms.
The listing notes this information should be treated as current for 2026, but applicants are strongly encouraged to confirm the current fund size, active investment rounds, and eligibility requirements directly with Connecticut Innovations before applying, since program details and open windows can change.
