Bicester AI firm PhysicsX becomes multi‑billion business

PhysicsX, which began life at Bicester Motion, recently secured a $300m (£223.9m) investment to support its expansion. In 2025, PhysicsX was valued at $1bn (£740m).

Founded by Robin Tuluie, the firm first set up operations in 2021 in a small office inside the Station Armoury at Bicester Motion before moving to the Gas Defence Centre as the team grew.

The company now employs more than 300 people and is based in London and New York.

Mr Tuluie said: “High-fidelity physics simulation has always been powerful, but it has also been slow, costly, and the preserve of a small group of specialists.

“Physics AI changes that in every dimension.”

The AI-driven engineering company uses artificial intelligence to support simulation and modelling.

Its approach helps improve speed, efficiency, and accessibility.

Mr Tuluie said the company’s technology is about broadening access to advanced tools.

He said: “We believe in the democratisation of this technology to broad technical profiles across an industrial organisation — engineers, designers, and operators who previously couldn’t run these analyses themselves.

“As that capability spreads, its utility compounds across the business.

“That’s the change we’re driving.”

PhysicsX began as a small venture at Bicester Motion and is now one of the UK’s biggest exponents of artificial intelligence.

Its recent investment is expected to accelerate its global growth.
