About the Carbon13 SEIS Fund
The Carbon13 SEIS Fund is your gateway to investing in the future of climatetech. Our eighth fund is open now.
The Carbon13 Venture Builder is one of Europe’s leading builders of high potential climatetech startups, and the SEIS Fund is the fuel for their growth.
We’re known as a beacon for investors seeking both financial gains and a profound impact on the planet.
We invest first cheque, but we’re building ventures that scale. These VCs are just a selection of those who have invested into our startups in follow-on rounds.

Materials Nexus is a deep-tech company originated at Cambridge University and Carbon13, who combine the insights of quantum mechanics with the power of AI to predict the properties of materials. Materials such as concrete, steel and glass contribute towards 50% of all CO₂ emissions. New, better materials are needed for a new, low carbon world – but it typically takes 20 years to develop a new material to be commercialised.
Their ground-breaking AI-enabled Materials Discovery Platform transforms the way new materials are designed using a rapid automated process and advanced quantum calculations that give high accuracy at larger scales.

3 billion tonnes of CO2e are emitted from methane in water each year. There is no way to remove this methane at scale. Until now. Bluemethane measures and removes methane from water. The methane is then used as a new source of clean energy. Their technology is scalable and can be deployed in a variety of settings, including wastewater treatment plants, reservoirs and rice cultivation. With methane’s global warming power 34x that of carbon, Bluemethane is tackling a core problem for global warming.
