TL; DR
London-based PhysicsX has raised $300 million in Series C funding at a $2.4 billion valuation led by Temasek, more than doubling in less than a year. An AI startup created by F1 cuts engineering simulation from days to seconds and is the fastest growing AI in data center hardware.
London-based PhysicsX has raised $300 million in a Series C led by Singaporean sovereign wealth fund Temasek, more than doubling its valuation to $2.4 billion, less than a year after a Series B valued the company at just under $1 billion.
The tour is oversubscribed. In addition to Temasek, which made its first investment in PhysicsX during the 2025 Series B round, new backers M&G Investments and Intrepid Growth Partners joined. Existing investors, incl NvidiaApplied Materials, Atomico, General Catalyst and Siemens increased their stakes.
What does PhysicsX do?
PhysicsX creates native artificial intelligence engineering platform it replaces conventional physics simulations that take hours or days with AI models that produce results in seconds. The technology is used in aerospace, automotive, semiconductor manufacturing, energy and materials manufacturing, and beyond cut aircraft design cycles from months to days.

The platform combines AI-driven fast physics with digital simulation to accelerate product development, reduce risk and optimize performance. PhysicsX calls this approach “Big Physics Models” as an analogy to the large language models that power chatbots but are applied to the physical equations that govern how engines, turbines and chips behave under stress.
Founded in 2019 by former Formula 1 engineers Jacomo Corbo and Robin Tuluie, the company came out of private in 2023 with a $32 million Series A round led by General Catalyst. Corbo was previously chief scientist and co-founder of QuantumBlack, the artificial intelligence division of McKinsey. Tuluie was head of R&D at Renault (Alpine) F1 and director of automotive technology at Bentley Motors.
Data centers as an engine of growth
The company’s growth is somewhat counter-intuitively driven by the AI ​​boom itself. The infrastructure required to build and operate data centers, gas turbines, compressors, cooling systems, semiconductor manufacturing creates a huge demand for the type of engineering simulation that PhysicsX accelerates.
“Right now, frankly, we’re very much on the supply side,” Corbo told the Financial Times, adding that the company had to adjust its offering to existing customers because of demand. According to him, semiconductors are expected to become PhysicsX’s largest industry segment this year.
The dynamic is unusual: an AI company whose biggest customers are companies that build the physical infrastructure that other AI companies need. Every data center cooling system, every chip package, every power turbine feeding an AI supply chain is a potential PhysicsX application.
Measure and stay in London
The Series C will fund US expansion and a new office in Singapore, Temasek’s home market. PhysicsX has grown its staff from 150 to 350 over the past year and has more than quadrupled its revenue in the past two years. Despite its international ambitions, Corbo said the company would remain headquartered in London, describing the city as a “wonderful place” to build a global business.
The $2.4 billion valuation puts PhysicsX among the UK’s most valuable AI startups, behind the likes of ElevenLabs and Ineffable Intelligence. He took the second place Sifted’s first AI 100Ranking of Europe’s most promising AI startups.
That’s the broader signal European deep technology may command frontier-level valuations when the technology solves a measurable industry bottleneck. PhysicsX does not create a chatbot or coding assistant. This builds the simulation layer upon which the companies building the physical infrastructure of AI depend. In a software-driven market, a company that helps design hardware faster is having its moment.
