Milvus Advanced develops nanomaterials that replicate the catalytic properties of scarce platinum-group metals using abundant elements like copper, nickel, and iron, targeting applications in hydrogen electrolyzers, clean energy, catalysis, and optoelectronics. The company operates a B2B model, delivering nanoalloy technologies and nanocatalysts to industrial players in green fuel production and energy infrastructure, with first commercial nanocatalysts planned for 2026 and early testing by leading customers. Its proprietary platform enables up to 70% cost reduction in electrolyzer catalysts without rare metals. Micol Churchill serves as COO. Milvus closed a $6.9 million seed round led by Hoxton Ventures, with participation from MD One, LQD Ventures, Übermorgen, Tuesday Capital, Mark Leslie Enterprises, van Den Bosch Dynasty Fund, Bluebirds, EQT Foundation (which invested 200k EUR as part of a 5 million pound seed), and Lowercarbon Capital. The company maintains operations in Oxford, UK, with a registered office in Woodford Green, Essex.
