A London-based deep tech company pioneering energy intelligence technology for battery packs has closed a £21 million funding round.
This brings total capital raised to over $44m since the company was founded in 2022 as a UCL and Faraday Institution spinout.
The round was co-led by BGF and AlbionVC, with follow-on participation from mobility specialist fund Autotech Ventures, UCL Technology Fund, DN Capital and Future Ventures.
Led by Steve Jurvetson, an early investor in SpaceX and Tesla, Future Ventures becomes the second early Tesla investor involved with Gaussion alongside board member Simon Rothman.
With much of the global battery industry focused on advances in cell chemistry, technologies extracting more from existing cells are attracting greater attention, particularly as AI infrastructure, electrified transport and autonomous systems place unprecedented strain on power supply.
Gaussion’s breakthrough technology – which uses an external magnetic field to enable rapid charging – improves the performance and lifespan of battery systems using proprietary, AI-enabled control software, with no change to battery chemistry or design.
The technology works with any lithium-ion battery across a wide range of applications, from charging EVs and drones in minutes to powering data centres, meeting sudden spikes in demand while maintaining battery longevity and reducing operating costs.
Gaussion is already working with several of the world’s leading vehicle, aerospace, energy-storage and consumer electronics manufacturers. In October 2025, growing demand enabled the company to move into a new 40,000 sq ft facility in central London, thereby opening one of the largest battery R&D locations in Europe.
Backed by 66 applications across 17 patent families, originating from its Faraday Institution research base, Gaussion’s technology is being evaluated across 14 active commercial programmes.
The company was recently identified by the UK Department of Business and Trade 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 US, Greater Together LA.
The additional investment 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.
“The race everyone’s watching is about computer chips – but the real prize is the battery,” said Tom Heenan, CEO and co-founder of Gaussion.
“The battery decides whether the giant computers behind AI can keep running. Whether a drone can stay in the sky. Whether a satellite survives out in space. Every battery faces a physics ceiling, and we move that ceiling.”
Dennis Atkinson, co-head of early stage at BGF, added: “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.”
Sebastian Hunte, investment director, AlbionVC, added@ “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.”
Oliver Christian, His Majesty’s Trade Commissioner to North America, said: “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.”
