Zenithon
Zenithon AI develops machine learning models that cut the time of complex physics simulations. It is starting with fusion energy and plans to expand into spacecraft, advanced propulsion and semiconductor manufacturing. It sells B2B to teams that run costly, slow simulations and experiments. The company was founded in 2025 and came out of King's College Cambridge's SPARK incubator. In 2026 it announced a $10M initial round led by Backed VC, with Seraphim, Lunar Ventures, MMC and SOSV also taking part.
