PhysicsX announced its oversubscribed $300 million Series C financing at a valuation of approximately $2.4 billion.

The round was led by Temasek, with participation from new investors including M&G Investments and Intrepid Growth Partners. Existing investors included Applied Materials, General Catalyst, Atomico, July Fund, NGP, NVIDIA, Radius, and Siemens, the company said in a press release.

Temasek began investing in the physics AI company for industrials last year and has played "an instrumental role in supporting the company's international expansion and growth," the company said.

This funding will accelerate the company's global growth, and 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.

PhysicsX is developing and deploying its AI-native engineering platform to accelerate hardware innovation and drive engineering and manufacturing productivity in industrial organizations. 

Aerospace & defense, energy, semiconductors, automotive, materials manufacturing, and data centers are under "more pressure than ever" to ship products faster, the company noted. 

“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. 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," said Jacomo Corbo, Co-founder and CEO of PhysicsX.

"That pressure collides with a reality that every engineer knows well: 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 behavior 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: from early-stage design and manufacturing through to real-time digital twins in operation.

“We believe in the democratization of this technology to broad technical profiles across an industrial organization — 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,” said Robin Tuluie, founder and chairman of PhysicsX.

PhysicsX has doubled its recognized revenue year-over-year and tripled its book value, while also more than doubling its customer count in the past year. 

The company, which has headquarters in London and an office in New York, has also doubled its headcount, now at 300 employees.
