Carbon13 is the venture builder for the climate-emergency



We are Carbon13, the venture builder for the climate emergency.

We are now working to create ~200 ventures that have the capacity to reduce CO2e emissions by 400 million tonnes. 32 innovative carbon emissions-mitigating startups have been launched so far by Cohorts 1-3 of Carbon13’s Venture Builder for the Climate Emergency, across sectors such as agriculture, renewable energy, the built environment, food, and materials. Cohort 4 began their entrepreneurial journey in September and applications are open now for Cambridge Cohort 5 along with applications for Berlin Cohort 1.

After an oversubscribed Carbon13 SEIS Fund III, we are now looking to raise capital for SEIS Fund IV. If you would like to learn more, please reach out to us directly.
