About us
Image Nium‘s novel nanotechnology is replacing Haber-Bosch, the most polluting industrial process on the planet to enable the synthesis of truly green ammonia for fertilisers and fuel.
Carbon13 is not just about investing in a few startups, it is about harnessing the entrepreneurial spirit. That means engaging with academia, business, policy makers, NGOs, consumers, new standards and finance. We need pioneers across the spectrum and that is where our community is critical to the success of our ventures and the transformation we need to see.
With origins across the Cambridge University ecosystem, world leading multinationals and successfully exited starts-ups, this team has deep experience in supporting founders, partners and investors.
Carbon13’s community of climatetech founders, Entrepreneurs in Residence, Experts, Investors and our Industry Partners all contribute to tackle the climate emergency.
Corporate partners work with us because they want to achieve ‘net zero’ emissions, drive innovation, engage staff and identify investment opportunities.

At Carbon13, our focus is not only on Carbon emissions or protecting Earth’s systems for the sake of Impact alone. Developing a scaling mentality from day one is essential to tackling an urgent and sizable problem—one that is increasingly shaped by the growing commercial drivers emerging from the fact that the cost of inaction on climate change now outweighs the cost of action. This dual imperative continues to shape how we support founders in building ventures that are both impactful and resilient.
As humanity begins to experience the effects of climate change, and organisations increasingly showcase their efforts to join the sustainability conversation, we are seeing a growing number of claims of action. To achieve its mission, Carbon13 focuses on understanding its own additionality—the unique ways it drives climate impact through entrepreneurship.
This is delivered across four key areas:
First, Carbon13 creates ventures that wouldn’t otherwise exist by connecting founders who might never have met, encouraging those unsure about entrepreneurship to take the leap, and helping individuals find the right cofounder. We are the first line in many of our founders’ stories.
Second, it supports ventures in becoming more impactful by accelerating growth through expert guidance, timely input, access to finance, and fostering effective and diverse teams. Founders are also trained to embed impact from the ideation stage, ensuring they become catalysts for meaningful change. Venture growth also naturally supports job creation and economic engagement.
Third, Carbon13 generates new knowledge that benefits even those who don’t progress with a venture. Many alumni report re-engaging with their careers in more impactful ways, applying what they’ve learned to support climate innovation elsewhere.
Fourth, Carbon13 actively addresses the lack of diversity in entrepreneurship through inclusive programme design, targeted outreach to underrepresented groups, and dedicated support for female founders. Indicators and data supporting these claims are presented in the impact report.
