Zenithon raises $10M to build world models for extreme physics

UK AI startup Zenithon has raised $10 million to build what it describes as the first world models for extreme physics and accelerate the development of technologies that will define the 21st century. Its backers include BACKED , Lunar, Seraphim, MMC, and SOSV, alongside founders and hyperscaler directors. Zenithon is developing “world models” — AI models that learn how complex physical systems behave and can rapidly predict the outcomes of different designs — for technologies including fusion r
