Carbon13’s SEIS Fund X is closing at the end of October. You can download the brochure on Syndicate Room, but here’s why early, exclusive access matters for this fund.

It’s how we fuel the ventures building on the Venture Builder in the UK, enabling investors looking to invest between £10k and £100k to take advantage of the SEIS tax reliefs (incl 50% off income tax) while ensuring that their capital will have true impact on the climate emergency.
Whether you’re new to SEIS (learn more about it here) or an experienced startup investor, here’s why the Carbon13 SEIS Fund X could be the right fund for you:
Carbon13’s SEIS fund is the *only* way individuals can invest in our Venture Builder startups at first cheque. It’s exclusive access.
And here’s why that matters >>>
- Exclusivity
- Early
- Growth Phase
The Growth Phase is 12 months of intensive support given to the startups post-investment, honed from 16 iterations and 113 investments. Your capital doesn’t just get equity in a startup, it gets one of Europe’s leading ecosystems working to grow them.
And it’s working – since 2024, 97% of Carbon13’s SEIS investments are operating today.
The teams are raising, including Auralytica, Climingo, Pure Capture Innovations, Viridys, Forge Minerals and Temperate in 2026.

Exclusivity
Exclusivity and why it matters >>>
Carbon13 doesn’t source deals for the fund. We build them.
We build the teams – 80 individuals join the programme. We’re starting with top class founders from day 1 because we selected 80 people from a highly competitive application process that sees hundreds of people try to get a coveted place.
32% PhDs. 57% have done a startup before. 37 is the average age. 30+% are women.
We then transform them into investable teams, e.g. the mission alignment, the complementary skills, shared values, healthy habits, governance and fast execution.
We have 15+ A Teams pitching for our capital and no one else can invest.
That means we’re not competing with other investors. We have clear water to focus on value.
Our teams all get the same deal, one that works for them and for the fund.
Early
Early.
Gets the worm.
But it’s the second mouse that gets the cheese…
Startups are high risk. Early startups are the highest risk.
The earlier the startup, the less evidence that proves it will succeed, the riskier it becomes to invest.
“Too early” rings in the ears of founders pitching VCs.
But, if you invest early, and get it right, you benefit from a lot more of the upside.
Carbon13 invests at arguably the earliest stage of any fund. We can invest before any other investor can build the case because we can reduce the risk because of the Venture Builder.
Pre-seed investing is usually about mitigating this risk through diversification, or personal expertise and judgement, or post investment support. Carbon13 does all of this on the VB yes.
But we do something else, which no one else can do: We get to know the founders really really well. We vet the founders through the application process, an in-depth form, two interviews.
We can greet every one of them by name on Day 1!
We then work closely with them as they form teams and develop the venture, embedding entrepreneurs in residence with them, lots of calls and feedback and practice and workshops and guidance. Because we get to know the teams so well over several months, we can build the confidence that this team, regardless of the traction data points or the TAM or the TRL, the team are going to succeed.
No other fund works so closely pre-investment pitch with the founders.
So we invest early, giving us the opportunity to catch the upside.
The Venture Builder is the unique platform that can give our portfolio the support post investment to grow, the exclusive dealflow, and the early access.
