A brief summary
Carbon13 builds and backs teams addressing earth’s critical life support systems. Initially this means addressing the most urgent problem of our time – climate change.
In our five-month Venture Builder programme, we bring together 80 bright minds from the fields of technology, science and business. With a great deal of support at all levels from us and our network of experts, they form teams, identify problem areas with significant potential for savings or reductions, and develop a climate tech startup in response.
If you want to start a climate tech venture from the best starting position without losing time, which the climate crisis doesn’t give us anyway, then start your application now. We count on you.
Here is a brief summary of what you can expect from the programme. If you still have questions after reading the programme, we recommend the upcoming webinars.

The Three Phases
Our Venture Builder programme is delivered in three phases over eight months. It's an intense programme, dedicated to one purpose; helping you take your potential and talent and turn it into a scalable venture that can significantly reduce CO2e emissions.
Phase 1: Teaming (ten weeks)
Phase 1 focuses on Teaming. You match with cofounders to form a team capable of building a game-changing venture which can reduce carbon emissions by millions of tonnes.
There will be a mandatory in-person component of Phase 1.
Only founders on the programme who successfully complete Phase 1 by forming a team will continue to Phase 2: Validation.
Phase 2: Validation (three months)
Phase 2 focuses on building proof points around the venture—especially its customers, the problem you are solving, and your value proposition.
At the end of Phase 2, teams who have met our criteria for progress become eligible to present to the Investment Committee, who will decide which ventures receive £120,000 and continue to Phase 3. You can read more about how our investment works in our FAQs.
Phase 3: Acceleration (three months)
Once you are in Phase 3, Carbon13 has invested in you and is your business partner. We work with an incredible network of enablers in Cambridge and Berlin, and with our corporate and financial partners, to help you build customer traction and momentum for your venture, including preparing a funding strategy for post-Carbon13 life and helping you bring in the next round of finance.

our four founder types
Each cohort on the Venture Builder is formed of four founder types to give the complementarities and depth that our ventures need. As part of the application process, we’ll ask you to help us understand which founder type best matches your profile, but of course, there is no such thing as a “typical” entrepreneur or team.
Technical Founders (Science/Engineering)
You are likely a scientist, an engineer, or someone with specialist technical knowledge relating to one of the CO₂e emitting sectors. You’ll be highly motivated to work on the biggest problems of Net Zero, and see entrepreneurship as your chance to build something significant. You may already be working on a prototype or IP, or wish to apply your skillset to the biggest challenges in decarbonisation. In a venture, you will likely be the CTO, responsible for leading the development of the technology to at least proof of concept stage.
This Founder Type is for software developers, data scientists, and/or AI/ML specialists. You want to build products which will actually make a difference to the climate crisis. You don't have to have your own idea, you may be more interested in teaming up with a commercial or hardtech founder who’s bringing their own idea or expertise in a particular sector. Your age, qualifications and experience are less important than your ability. In a founding team, you may take a CTO role, or a role similar to a Chief Data Officer or Chief Information Officer – leveraging the potential for data analysis, software, intelligent automation, and machine learning.
Technical Founders (Software/Data/ML)
Commercial Founders
In this Founder Type, we’re looking for founders with the skillsets and experiences to take on the CEO, COO or Chief Commercial Officer roles. You’ll be responsible for building the critical relationships the venture needs (e.g. customers and investors), and for leading the building of the execution team. Often, Commercial Founders are serial entrepreneurs, or senior commercial leadership in corporates, or experienced operators from emitting industries with deep commercial insights into their sector. You may be working on an idea already, but many of those who join us from this Founder Type either don’t have a fixed idea, or are open to the ideas other Founder Types are bringing.
This is the category for determined change-makers who don’t fit into the other Founder Types. You bring skills or experiences which enable your founding team to think outside of the box, to fast-track into new directions or industries. For example, you may be a talented designer, farmer, product manager, or sustainability expert. Or, you’ve spotted a great opportunity in an emitting sector you know well and want to bring that to the cohort.
