Gaussion, a startup developing energy intelligence technology for battery packs, has raised £21 million in funding co-led by BGF and AlbionVC, with follow-on participation from Autotech Ventures, UCL Technology Fund, DN Capital and Future Ventures. The round brings total capital raised to over £33 million since the company was founded in 2022 as a spinout from University College London and the Faraday Institution. The funds will be used to scale commercial deployment of MagLiB, Gaussion's magnetic PCB retrofit system, and Aeon, its proprietary control chip and software platform, across the automotive, aerospace, data centre and consumer electronics sectors.
Founded in 2022, Gaussion develops technology that uses an external magnetic field to enable rapid charging of lithium-ion battery packs. The approach improves battery performance and lifespan using proprietary, AI-enabled control software, with no change to battery chemistry or design. MagLiB and Aeon work together to create an intelligent control layer inside battery packs, enabling applications ranging from charging EVs and drones in minutes to powering data centres and managing sudden spikes in demand, while maintaining battery longevity and reducing operating costs.
Much of the global battery industry has focused on advances in cell chemistry, but technologies that extract more from existing cells are attracting greater attention as AI infrastructure, electrified transport and autonomous systems place increasing strain on power supply. Gaussion's technology is compatible with any lithium-ion battery across a wide range of applications and is backed by 66 patent applications across 17 patent families, originating from its Faraday Institution research base.
Gaussion is already working with several of the world's leading vehicle, aerospace, energy-storage and consumer electronics manufacturers, with technology currently being evaluated across 14 active commercial programmes. In October 2025, growing demand enabled a move into a new 40,000 sq ft facility in central London, establishing one of the largest battery R&D locations in Europe. The UK Department of Business and Trade recently identified Gaussion as one of a small number of innovative companies representing sectors crucial for economic growth, with CEO and co-founder Tom Heenan chosen to attend the largest ever UK trade mission to the United States, Greater Together LA.
Future Ventures, led by Steve Jurvetson - an early investor in SpaceX and Tesla - joins the round as a new participant, becoming the second early Tesla investor involved with Gaussion alongside board member Simon Rothman.
Gaussion has made huge strides in a short space of time to validate its technology, scale operations and increase commercial traction. The business possesses a truly differentiated offering, underpinned by an incredibly versatile product, with the potential to address a fundamental performance and cost issue in battery systems. We are delighted to invest in Gaussion for a third time, made more exciting as the deal that took BGF over the threshold of £5 billion invested in UK & Irish businesses.
Batteries underpin the modern world, from EVs and grids to consumer devices and data centres, yet every battery faces the same fundamental ceiling on performance and lifespan. Gaussion has created a new layer in the battery stack: a magnetic intelligence layer that dramatically lifts performance across any chemistry or format. It is a rare opportunity to back a company that touches the entire battery lifecycle, from gigafactory formation to deployment, and we are delighted to continue to support the team as they accelerate the commercial rollout across target verticals.
Greater Together LA brought together our shared values — innovation, creativity, and entrepreneurship — to unlock new opportunities for both our economies to grow and thrive. Gaussion is a brilliant example of why the UK is Europe's number one tech ecosystem and how British deep tech can generate world-leading solutions with global commercial potential. As we deepen our technology partnership with the United States, companies like Gaussion demonstrate why the UK remains one of the world's most exciting places to innovate, invest, and do business.
