A UK physics AI company has been valued at a mammoth £1.8 billion by its latest funding round.
PhysicsX is developing and deploying its AI-native engineering platform to accelerate hardware innovation and drive engineering and manufacturing productivity in industrial organisations.
The firm is headquartered in the United Kingdom, with offices in London and New York, and an expanding presence in San Francisco’s Bay Area and Singapore.
The round is led by Temasek, with participation from new investors M&G Investments and Intrepid Growth Partners, alongside existing investors including Applied Materials, Atomico, General Catalyst, July Fund, NGP, NVIDIA, Radius, and Siemens.
Temasek first invested in PhysicsX in 2025.
The sectors that build the world’s most critical hardware — aerospace & defense, energy, semiconductors, automotive, materials manufacturing, data centres — are under more pressure than ever to ship better products on tighter timelines. However the simulation workflows at the heart of hardware development are slow, expensive and difficult to scale.
PhysicsX says its software stack is built to remove this bottleneck. Its AI models predict physical behaviour in seconds rather than hours or days, enabling engineering teams to evaluate orders of magnitude more design variants and carry physics insight across the full product lifecycle.
The financing comes amid rapid growth. PhysicsX has doubled year-over-year recognised revenue, tripled booked revenue, while more than doubling its customer count over the past year. The team has grown to more than 300 people, doubling in size in the last 12 months.
This round will accelerate the company’s global growth, the expansion of its platform capabilities, and frontier research, including the development of larger, more powerful pre-trained physics AI models, known as Large Physics Models.
“Almost every hard problem in the physical economy — better aircraft, better chips, better engines, better energy systems — comes down to how fast and how well engineers and machine operators can work through the underlying physics,” said Jacomo Corbo, co-founder & CEO of PhysicsX.
“For decades, that has been the binding constraint on hardware innovation. Physics AI removes it. We are giving engineers the ability to explore thousands of designs where they once managed a handful, in seconds rather than weeks, across the most demanding industries in the world.
“We are also enabling more reliable, more efficient, and altogether new ways of doing engineering, manufacturing, and production. This financing lets us put that capability in the hands of more engineers and push the frontier toward ever larger and more capable Large Physics Models.”
Robin Tuluie, founder and chairman of PhysicsX, added: “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.
“It makes high-fidelity simulation dramatically more efficient, augments and improves on pure simulation results with ingestion of real-world data into our Large Physics Models, and opens it to applications that were never practical before.
“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.”
