Zenithon AI raises $10 million to accelerate physics simulations

The London startup is training world models for extreme-physics engineering problems.

Financing and investors

Backed VC led the $10 million financing. Seraphim Space, Lunar Ventures, MMC Ventures and SOSV participated, alongside founders and directors from major cloud-computing companies.

Model development and commercial expansion

Zenithon plans to develop models for engineering problems that make conventional simulations slow and costly, beginning with fusion. The company describes evaluating many more design options as its target, with spacecraft, propulsion and semiconductor applications also planned.

The funding supports model development, growing the team from 11 to 17 people and expanding commercial work in San Francisco and elsewhere in the United States.
