Gigaton
Gigaton was founded in 2020 as Carbon Re, the first university spinout jointly backed by University College London and the University of Cambridge, drawing on UCL Energy Institute and Cambridge Institute for Manufacturing. Co-founded by Daniel Summerbell, Buffy Price, Sherif Elsayed-Ali, and Dr Aidan O Sullivan, and now led by chief executive Josh Vernon, the company rebranded to Gigaton in 2024. It builds self-learning AI control software that uses deep reinforcement learning to simulate, predict, and autonomously control complex industrial processes, cutting fuel costs and carbon emissions. Starting with the cement pyroprocess, one of the hardest industries to decarbonise, Gigaton is expanding into steel, glass, and chemicals, aiming to run the fully autonomous plants that legacy control systems cannot. In June 2026 it raised a $26M (£19.3M) Series A led by Plural, building on earlier backing from Clean Growth Fund, the UCL Technology Fund, and Cambridge Enterprise.

Seabound
Seabound was founded in late 2021 by Alisha Fredriksson and Roujia Wen, who met while studying at Minerva University. Fredriksson, a Swedish-Canadian climate entrepreneur, previously built Liquid Wind, a maritime e-fuel startup. Wen, a Chinese engineer with expertise in mathematics and theoretical physics from Cambridge, leads technology and systems development. The company developed a compact, retrofittable system that captures CO2 from ship exhaust and converts it into solid carbonate pellets for offloading at ports. Seabound completed its first full-scale maritime carbon capture units in February 2026 and has won the UK Government's Clean Maritime Demonstration Competition twice. The company secured a €1.5M European Space Agency award and has raised $6.8M in seed funding from YCombinator, Lowercarbon Capital, EMLES Venture Partners, and strategic investors Eastern Pacific Shipping and Lomar.
Isometric
Isometric was founded in 2022 by Eamon Jubbawy, who previously co-founded Onfido where he served as COO and President, scaling the company to verify over one billion identities before its $650M acquisition by Entrust. Jubbawy studied Economics and Management at Keble College, Oxford. Isometric addresses trust in the carbon removal market through an AI-native science platform that issues monthly certificates with real-time expert verification, maintains a comprehensive registry with full evidence documentation, and operationalises verification protocols. The company serves major enterprises including Google, Microsoft, Shopify, Anglo American, and Molten, and maintains a network of over 400 scientists and ecosystem partners. Isometric raised $25M in seed funding co-led by Plural and Lowercarbon Capital, with participation from angel investors including Niklas Zennstrom (Skype), David Helgason (Unity), and Ilkka Paananen (Supercell).
