PHYSICS X has secured $300 million in a Series C funding round, valuing the AI-driven engineering software startup at $2.4 billion. This follows a Series B round approximately 12 months ago, more than doubling the company's previous valuation. The funds, led by Temasek and supported by existing investors like Nvidia and Siemens, will fuel platform development, AI research, and expansion into the US and Singapore, where PHYSICS X currently employs around 350 people.
