A growing number of investors are turning their attention to climate-focused startups as demand rises for technologies capable of addressing environmental challenges.
Against that backdrop, Carbon13 has unveiled its latest investment vehicle aimed at supporting the next generation of founders developing solutions across multiple industries impacted by climate change.
Carbon13 Introduces Its Tenth SEIS Investment Fund
Climate-tech venture builder Carbon13 has announced the launch of Carbon13 SEIS Fund X, marking the tenth fund in its Seed Enterprise Investment Scheme (SEIS) series.
The new fund is designed to support startups emerging from the company’s Venture Builder programme in Cambridge, United Kingdom.
The initiative reflects Carbon13’s continued commitment to identifying and backing entrepreneurs working on technologies that can contribute to reducing emissions while strengthening resilience across critical sectors of the economy.
Focus on High-Impact Climate Innovation
The newly launched fund will target businesses operating across a broad range of climate-related industries.
Investment priorities include innovations in energy systems, artificial intelligence applications, advanced materials, food security solutions, and technologies that improve supply chain resilience.
By maintaining a wide investment scope, the fund aims to support founders tackling some of the most pressing environmental and economic challenges facing businesses and societies today.
Support Beyond Capital
In addition to financial backing, Carbon13’s SEIS Fund X offers participating startups access to a 12-month portfolio support programme.
The initiative is designed to improve the chances of successful company development and graduation by providing guidance, resources, and strategic support during critical growth stages.
The programme seeks to help early-stage ventures navigate common challenges, refine their business models, and accelerate their path toward commercial success.
Leadership Driving Continued Expansion
The organisation is led by Michael Langguth, who serves as Co-founder and Chief Strategy Officer.
Under its leadership team, Carbon13 has established itself as a significant player in the European climate-tech ecosystem.
Since 2021, the venture builder has invested in more than 100 companies across the United Kingdom and the European Union, helping founders transform climate-focused concepts into scalable businesses.
Building a Broad Climate-Tech Ecosystem
A key feature of Carbon13’s Venture Builder programme is its extensive network of contributors.
Startups accepted into the programme gain access to hundreds of specialists, including industry experts, scientific advisers, investor partners, and corporate collaborators.
This ecosystem is intended to provide founders with both technical expertise and commercial insight, helping them move innovations from development stages into real-world deployment.
Portfolio Companies Demonstrate Early Success
Several startups that have emerged from the Carbon13 ecosystem have already attracted attention within the climate-tech sector.
Among its notable alumni are Cocoon Carbon, MatNex, Textrax, and Nanoplume.
With the launch of Fund X, Carbon13 is seeking to build on those successes by providing fresh capital and support to another wave of entrepreneurs developing technologies aimed at addressing climate challenges while creating long-term economic value.
