London-based PhysicsX has secured $300M from investors led by Singaporean sovereign wealth fund Temasek, valuing the seven-year-old AI start-up at $2.4B. This marks a significant jump from its previous valuation of nearly $1B less than a year ago, making it one of the UK's most valuable AI companies.

The company, founded by former Formula 1 engineers, applies AI to design products across manufacturing and defence sectors, including engine and drone components. Co-founder and CEO Jacomo Corbo acknowledged they're 'supply-side limited' and actively throttling rollout at existing customers amid surging demand.

PhysicsX joins an elite group of British AI ventures, trailing only behind ElevenLabs ($11B) and Ineffable Intelligence ($4B). The fresh capital will fund US expansion and establish a Singapore office, supporting growth in semiconductor and data-center infrastructure markets. The workforce has already doubled to 350 employees.

Demand for industrial AI solutions is accelerating alongside the global data-center boom, pushing PhysicsX to scale rapidly. Corbo emphasized the company will maintain its London headquarters while pursuing global ambitions, leveraging partnerships like its work with the GB1 America's Cup team to demonstrate engineering capabilities across high-value industrial segments.
