Solve the most urgent problems in climate and build the solutions - become a cofounder of a scalable climatetech startup through Carbon13’s Venture Builder.

Software is crucial to how our world can decarbonise the way it travels, eats, makes and powers the world - and developers use Carbon13 to focus only on the most urgent problems, to make the biggest impact on emissions as quickly as possible.

We're looking for developers, data scientists or Machine Learning specialists to become co-founders/CTOs of startups that fight climate change, through joining our eight-month Venture Builder programme which starts on the 14th March. Apart from 9 days in Cambridge, you can participate in the rest of the programme from anywhere in the UK.

You'll join a cohort of over 70 founders, made up of scientists, experienced founders, leaders from emitting industries, engineers, sustainability leaders, and more. All are ready to find a cofounder and start working on solutions that can reduce carbon emissions by millions of tonnes.

What startups have developers built on Carbon13?

Through the eight-month Venture Builder, software ventures that founders have launched so far include materials discovery through quantum computing, AI-driven design of low carbon buildings, intelligence for green investment, regenerative farming platforms, and commercial food waste management. You can view our portfolio of ventures at www.carbonthirteen.com/our-portfolio

Working on an MVP?

Unlike accelerators, you do NOT need an idea or MVP to join Carbon13, though you can apply with one if you do. You will either be supported to find an idea to develop which can significantly reduce emissions, or join a cofounder/team who bring IP or an idea or strong insights into an emitting industry

You may choose to apply your skills to a software idea or you may choose to cofound a hardtech or deeptech startup with a scientist/engineer cofounder. Half of our ventures are software, half are science-based/hardtech.

Applications are open now for our next cohort

Cambridge Cohort 5 starts 14th March - apply by 7th March

It is possible to start this programme alongside a full time job and many of the 80 cohort members chose to do so. Apart from nine in-person days in Cambridge, you can do the programme from anywhere in the world. The rest of the programme is delivered remotely. Please get in touch if you questions about the time commitment.

Our mission: Save the climate and aim big - before it's too late

Carbon13 is the Venture Builder for the Climate Emergency. We are laser-focused on supporting founders solving for the climate, and the climate only. To do that, we ask every new founder on our Venture Builder to aim big, to build a solution with the potential to reduce carbon dioxide (or equivalent greenhouse gases) by 10 million tonnes per year - and all our support is designed to help you reach that figure.

Why? The climate doesn't have time for us to waste on false starts, tinkering at the edges, or greenwashing.

How does Carbon13 work?

On Carbon13 you are building a startup as part of a cohort of 70 founders. You are not sat in a room being told what you already know. Our programme is designed to amplify the work you're doing, because the planet doesn't have time to waste on theory or incremental ideas.

-Phase 1: Teaming & Ideation in 6 weeks

You will find a cofounder in the first 6 weeks. As a technical founder you most likely will team up with a founder with a proven track record in founding startups or industry leadership in emitting sectors. On average 90% of the 70 founders on the cohort form teams within 6 weeks.

-Phase 2: Validation in 9 weeks

Your team will intensely work on:

-Phase 3: Acceleration in 4 months

After Phase 2, we invest pre-seed into 14 ventures. They then use Phase 3 to focus on market, product, business model and strategy to prepare the venture for further seed-stage investment.

We also help you look at scaling strategies, managing growth pains and developing a funding strategy.
