. The valuation more than doubles from just under $1 billion during its Series B less than a year ago, marking one of the fastest value increases among European AI startups. New investors M&G Investments and Intrepid Growth Partners joined the round, while existing backers including Nvidia, Applied Materials, Atomico, General Catalyst, and Siemens increased their stakes 1

Transforming Engineering with AI Physics Simulation

PhysicsX builds an AI-native engineering platform that replaces conventional physics simulations, which take hours or days, with AI models delivering results in seconds 1

. The technology serves aerospace, automotive, semiconductor manufacturing, energy, and materials production industries, already cutting aircraft design cycles from months to days. The platform combines fast AI-driven physics inference with numerical simulation to accelerate product development, reduce risk, and optimize performance. PhysicsX calls this approach "Large Physics Models," analogous to large language models powering chatbots, but applied to physical equations governing how engines, turbines, and chips behave under stress 1

Founded in 2019 by Jacomo Corbo and Robin Tuluie, both former Formula 1 engineers, the company emerged from stealth in 2023 with a $32 million Series A led by General Catalyst 1

. Corbo, previously chief scientist and co-founder of QuantumBlack, McKinsey's AI division, explained the mission: "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" 2

Data Centre Infrastructure Drives Rapid Growth

The AI boom itself drives PhysicsX's growth through infrastructure demands. Data centres require gas turbines, compressors, cooling systems, and semiconductor fabrication, creating enormous demand for engineering simulation acceleration 1

. "Right now, candidly, we are very supply-side limited," Corbo told the Financial Times, noting the company moderates its rollout to existing customers due to overwhelming demand. Semiconductors are expected to become PhysicsX's largest industry segment this year 1

. Every data centre cooling system, chip package, and power turbine feeding the AI supply chain represents a potential PhysicsX deployment, positioning the company at the intersection of AI software and physical hardware infrastructure.

Global Expansion While Maintaining London Base

PhysicsX doubled its team over the past 12 months, growing from 150 to more than 350 employees, and more than quadrupled revenue over the past two years 1

. The Series C funding will support global expansion in the US and a new office in Singapore, Temasek's home market 1

. Despite international ambitions, Corbo confirmed the company remains headquartered in London, describing the city as a "wonderful place" to build a global business. The $2.4 billion valuation places PhysicsX among the UK's most valuable AI startups, ranking second in Sifted's inaugural AI 100 1

. The company plans to accelerate platform capabilities and research, developing larger, more powerful pre-trained physics AI models that give engineers the ability to explore thousands of designs in seconds rather than weeks 2
