Job Description

Become a co-founder of a startup that fights climate change.

If you want to fight climate change, then Carbon13 is currently the strongest launchpad for you to build a decarbonisation venture from scratch— because our Venture Builder programme is the only place where a commercial cofounder can do all these three things:

  1. Find their technical cofounder among the scientists, developers and engineers who make up the rest of our cohort (~90% find a cofounder)
  2. Understand the carbon intelligence of their solution to maximise its potential to reduce emissions
  3. Develop both the commercial and strategic groundwork to scale the startup to 10 million tonnes of emissions reduction.

Typically, commercial founders include entrepreneurs, operators, corporate professionals, commercial directors from industry, anyone with a track record of execution and commercial acumen. You will most likely become the CEO of the startup and lead on the commercial strategy, fundraising and customer development.

Working on a climatetech idea already?

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 with strong insights into an emitting industry and together execute the implementation of their validated customer pain points.

As a commercial founder, 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. You can view our portfolio of ventures at

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 10x the work you're doing, because the planet doesn't have time to waste on theory or incremental ideas.

-Phase 1: Teaming in 6 weeks

You will find a cofounder in the first 6 weeks. As a commercial cofounder you most likely will team up with a technical cofounder from a science, engineering or software background. On average 90% of the 70 founders on the cohort form teams within 6 weeks.

-Phase 2: Ideation & Validation in 9 weeks

Your team will intensely work on:

Team strengthening | Carbon intelligence | Rapid iterations of concepts | Business model forming | Prototype testing | Intellectual property | Customer development | Stakeholder development | Behaviour change | Governance | Venture incorporation

-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.

The next cohort will begin in Cambridge, UK on 19th September 2022. (Apart from nine in-person days in Cambridge, you can do the programme from anywhere in the world.)
