Oxford-based deep tech startup is building atomically engineered fuel cells: 85% cheaper and 30x more power-dense, running on renewable liquid fuels.
Oxford/San Francisco, May 19th, 2026 – Amphiform, a deep tech company building a new generation of nano-catalyst energy materials, has closed a $5.5M pre-seed round led by General Catalyst, co-led by Main Object and with Embassy Ventures, K5/Tokyo Black, Thomas Wolf, Charlie Songhurst and other angel investors participating.
Today’s fuel cells are heavy and underpowered. The chemistry that generates electricity happens only at a thin interface where catalyst, fuel, electrons and protons meet. Most of the “deep” expensive catalyst is never used.
