Molyon
Molyon is a University of Cambridge spinout from the Department of Materials Science and Metallurgy developing next-generation lithium-sulphur batteries with double the energy density of conventional lithium-ion cells. The company emerged from 15 years of research by Professor Manish Chhowalla, focusing on metallic molybdenum disulfide as a breakthrough cathode technology. Founded in February 2024 by Dr Ismail Sami (CEO) and Dr Zhuangnan Li (CTO), who met while studying under Chhowalla, the startup has demonstrated batteries achieving energy densities of 500 Wh/kg compared to approximately 250 Wh/kg for typical Li-ion cells. In November 2024, Molyon secured €4.3M in seed funding co-led by IQ Capital and Plural, with participation from Cambridge Enterprise and ParkWalk, targeting initial applications in drones and robotics.

Nyobolt
Nyobolt was established in 2019 to commercialise breakthrough battery research from the University of Cambridge's Department of Chemistry. Co-founded by Professor Dame Clare Grey, a Royal Society Fellow with decades of battery research expertise, and CEO Dr Sai Shivareddy, who holds a Cambridge PhD and previously collaborated with Dyson on energy storage. The company's core innovation uses niobium tungsten oxide as an anode material, enabling rapid ion mobility that multiplies charging speeds compared to conventional graphite anodes. In June 2024, Nyobolt made history as the first company to demonstrate five-minute EV charging, going from 10% to 80% in four minutes and 37 seconds. The company closed 2024 with $9M in revenue and over $150M in signed customer contracts spanning AI data centres, autonomous robotics, and electric vehicles. Nyobolt has raised $100M to date across multiple rounds.
IONATE
IONATE was founded in 2019 by Matthew Williams, Robert Ricci, and Luca Mezossy-Dona to modernise century-old power infrastructure through intelligent hardware and software. Williams brings 15 years of experience as an electrical and control engineer, having previously founded The Faraday Grid. The company's flagship product is the Hybrid Intelligent Transformer (HIT), a solid-state transformer providing precision power flow control up to 36 kV, paired with the Aurora Neuralis distributed control software for system-level optimisation. IONATE was named a front-runner in hybrid transformers by Cleantech Group's 2026 Global Cleantech 100 and featured in the IEA's 2026 State of Energy Innovation Report. The company closed a £3.3M seed round in 2022 led by IQ Capital, followed by a $17M Series A in February 2025 led by AlbionVC with participation from IQT and strategic investors.
Proxima Fusion
Proxima Fusion was founded in April 2023 as a spin-out from the Max Planck Institute for Plasma Physics, bringing together scientists and engineers from IPP, MIT, and X Development. Co-founded by Dr Francesco Sciortino (CEO, PhD in plasma physics from MIT) and Dr Lucio Milanese (COO, PhD in theoretical plasma physics from MIT, formerly McKinsey), the company is developing quasi-isodynamic stellarators combined with high-temperature superconducting magnets to build the world's first commercial stellarator fusion power plant. Proxima has partnered with RWE and the Free State of Bavaria on a planned €2B facility near Munich. The company has raised €200M to date, including a Series A led by Cherry Ventures and Balderton Capital with participation from Lightspeed Venture Partners, Plural, and others. Proxima maintains a UK presence at the Culham Campus and a London-registered entity.
