Carbon13 is delighted to announce that we have secured the first close of a target fund size of €30 million (£26 million). This first close will be deployed into a total 19 startups which, in another major milestone, include our first six Germany-based climate tech startups all built through our Venture Builder based in Berlin. These six are each receiving €120k investment.

The total Carbon13 portfolio now numbers 64 startups and when we look at their collective potential impact on carbon, they are working towards an annual mitigation potential of over 500 million tonnes of CO2e.

“We continue to see the results from combining world-leading talent and ingenuity with a burning passion to combat the climate, now in Berlin in addition to Cambridge. As the commercial drivers in this space become clearer, so does the magic of innovation in the art of what is possible and this is what is luring investors from all across the world.” –  CEO & Co-founder of Carbon13, Dr Nicky Dee

Commenting on the investments and carbon abatement potential of the six ventures, Chief Strategy Officer & Co-founder of Carbon13, Michael Langguth, said:

“Over the last two years, we have received thousands of applications to our programmes, selected over 500 founders to join and co-founded over 140 startups with them. This round of investments takes the total to 64 pre-seed investments in climate tech startups from the Carbon13 funds. This makes us one of the most active investors in the climate tech space. As a result, the collective abatement potential of our startups is now over half a gigaton of CO2e, more than 1% of global emissions. Our sights are set on making sure this potential is maximised and expanding it significantly through more programmes, startups and enhancing the acceleration process.


“Germany is now a rapidly developing hotspot for us; some of the most impactful and exciting ventures begin life thanks to our Berlin operation now. As a result, for the first time, we have now invested in ventures from our Germany-based Venture Builder. This current group is made up of incredibly strong personnel with a high level of diversity: all teams have at least one female co-founder and come from 10 different nationalities. A sign of things to come!”

Our potential on carbon

The new Fund and German expansion is set to propel a total portfolio of 64 Carbon13 ventures towards their impressive carbon abatement targets. Carbon13 ventures are collectively working towards an annual mitigation potential of over 500 million tonnes of CO2e (0.5 gigatonnes). This number is now set to rise further with each additional investment made by Carbon13.

The six ventures receiving investment from the Carbon13 Fund in Germany:
A digital nutrition coach for microbes that accelerates the transition to a circular bioeconomy

Flexible and scalable EV charging service powered by sustainable batteries

Developing low-energy carbon dioxide capture and permanent storage solutions

Unlocking the full potential of biochar for soil and fertilizer improvement 

Hoop Solar
Unlocking gigawatts of solar energy on plastic greenhouses 

Reducing maritime carbon with de-risked vessel retrofits

What sets Carbon13 apart – entrepreneurship X carbon impact

Carbon13 was born out of the belief that entrepreneurs will play a significant role in transforming our world for Net Zero. However, this will only happen if they are empowered to create truly impactful startups that can measurably and credibly reduce emissions by millions of tonnes.

We do this by supporting founders to use first principles thinking to maximise potential carbon reduction in their value propositions from the start. We empower our founders to make strategic decisions on carbon, so that they’ll continue to scale their impact long after they leave our programmes.

We’ve worked with over 500 founders, who chose to build their startups with us because we bring the scientific rigour of our Cambridge origins, the EU/UK investment networks, and the deep commitment to fighting the climate crisis.

This approach can be seen in notable Carbon13 alumni including Kita, Infyos, Nium, Biozeroc and Materials Nexus.

Who we invest in

Carbon13 only invests in ventures formed or built on their two programmes, the Venture Builder Cambridge and Berlin and the Venture Launchpad. The Venture Builder sees a cohort of 80 high potential founders come together to form cofounding teams and develop a venture with the minimum potential for reducing CO2e emissions by 10 million tonnes per year when at scale. The Venture Launchpad is an accelerator which takes early-stage teams, creates a powerful brains trust around them, and supports them to maximise their carbon impact to the same 10 million tonne target.

Carbon13 has invested over £7 million into startups in the UK since 2021. The LP Fund will enable us to invest outside of the UK, invest in follow on rounds and thereby expand our impact further.
