Carbon13 SEIS Fund

Linking climate action to investment opportunity

Carbon13 is the venture builder for the climate emergency. By the end of 2024, we will select and support 1500 entrepreneurs through the venture builder, linking them to the Cambridge sustainability network and our corporate partners.

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 certified high net worth investors, certified sophisticated investors and self-certified sophisticated investors the opportunity to invest in the next generation of high-growth businesses focused on the climate emergency (see Disclaimer below).

  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.
