Carbon13 SEIS Fund

Linking climate action to investment opportunity

Carbon13 is the venture builder for the climate emergency. Over the next 5 years, we will select and support 1000 entrepreneurs through the venture builder, linking them to the Cambridge sustainability network and our investor network.   

These entrepreneurs will build scalable ventures with the potential to reduce carbon emissions by over 400 million tonnes or 1% of global emissions.    

The Carbon13 SEIS Fund offers sophisticated and high net-worth investors the opportunity to invest in the next generation of high-growth businesses focused on the climate emergency (see Disclaimer below).

Investment Criteria

  1. The Carbon13 Seed Fund investment will get the ventures to a value point where they can raise outside seed investment or venture capital. All ventures must have the potential for high growth and to reduce carbon emissions by 10 million tonnes. 

  2. Carbon13 is business model agnostic – digital, technical and traditional business models all have a role to play in a net zero economy. 

  3. Carbon13 expects its venture founders to reflect a diverse cross-section of society. It is our strong belief that diversity leads to better outcomes for early stage ventures and we will strive to achieve this ambition.  

  4. Ventures will be UK domiciled and we require them to be SEIS eligible.
