Nominal lands $240 million Series C, lifting valuation to $3 billion
Lightspeed Venture Partners led the financing, with Insight Partners as co-lead. The hardware engineering startup was valued at $1 billion in March.

Nominal said on November 9, 2026, that it had raised $240 million in Series C financing, bringing its valuation to $3 billion. The round was led by Lightspeed Venture Partners, with Insight Partners serving as co-lead.
The Austin-based company develops an AI platform for engineers designing and testing complex hardware, from aircraft to nuclear reactors and smart factories. Founded four years ago, Nominal says it serves 80 organizations in the commercial and government sectors.
The new valuation is triple the $1 billion valuation in the company's March announcement of a $155 million Series B extension. Trae Stephens at Founders Fund led that financing, which originated with an investor offer rather than a fundraising effort by Nominal.
In October, the Air Force chose Nominal for a $71.2 million investment through its Strategic Funding Increase (STRATFI) program. The program requires funds from outside the Air Force to match its investment.
Defense company Anduril, co-founded by Stephens, is among Nominal's key customers. Nominal's CEO and co-founder, Cameron McCord, previously worked at Anduril and served as a U.S. Navy submarine officer. Sequoia, General Catalyst and Lux Capital are also investors in Nominal.
