Accelerator-based isotope refinery for medical isotopes and fusion tritium
StandardX is a UK-headquartered deep-tech company founded in 2025 by nuclear engineers Dr Richard Pearson (CEO, formerly co-founder of Kyoto Fusioneering) and Dr Ross Allen (CTO). It is building what it calls the world's first isotope refinery: a compact, deployable particle-accelerator platform meant to produce a full portfolio of rare isotopes on one standard industrial footprint instead of isotope-specific reactors and cyclotrons. It is starting with isotopes for cancer diagnosis and therapy, including targeted alpha therapies, and later plans to make tritium for fusion power plants. On 2026-09-23 it announced a £10M seed round co-led by Vsquared Ventures and East X Ventures, with a team of 15 and plans for a London industrial site.
