What we're looking for
We're looking for scientists, engineers and inventors to become co-founders of startups that fight climate change, through joining our eight-month Venture Builder - starts in late October.
Whether you're working on a startup idea already or not, you'll use the Venture Builder to find a cofounder, develop the idea, and launch an investable startup with the potential to mitigate emissions by millions of tonnes.
You'll join a cohort of over 80 founders, made up of scientists, experienced founders, leaders from emitting industries, engineers, sustainability leaders, and more. The average age is usually around 37, but our youngest and oldest participants have been 23 and 60+ respectively.
All are ready to find a cofounder and start working now on solutions that can reduce carbon emissions by millions of tonnes.
Apart from a few days in Berlin, you can participate in the rest of the programme remotely.
Why? The climate doesn't have time for us to waste on false starts, tinkering at the edges, or greenwashing
Apart from nine in-person days in Berlin, you can do the programme from anywhere in the world. The rest of the programme is delivered remotely. Climate doesnt have time for false starts, begin your entrepreneurship journey the right way with us, avoid the dead ends or incremental impacts. We train you deep carbon knowledge that will enable you to build your startup in a way that climate tech VCs will need to invest.
“One of the unique things that we are doing at Carbon13 is we are not expecting our founders to outsource this knowledge, we are very much training all of our founders, so they have access to the latest tools and techniques, so that they can assess their carbon mitigation potential, understand how to communicate it and of course be transparent in how they are measuring it.”
Carbon13 Co-Founder and Chief Sustainability Officer Dr. Nicky Dee
What startups have scientists and engineers built on Carbon13?
Through the eight-month Venture Builder, deeptech and science-based ventures that founders have launched so far include:
Materials Nexus - materials discovery through quantum computing
Nium - green ammonia, replacing Haber-Bosch
Sun Bear Biofuture - alternative palm oil through precision fermentation
Biozeroc- carbon negative concrete
Ki Hydrogen - biomass electrolsysis for low energy green hydrogen production
Bluemethane - methane capture from water
You can view our portfolio of 80+ ventures here.
Working on a startup idea or IP?
Many entrepreneurial scientists and engineers choose our Venture Builder because they're already working on an idea or have IP which they want to develop and commercialise. However, this is not a requirement and around half our technical founders do not have an idea for a climate startup. 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. Half of our ventures are software, half are science-based/hardtech.
