Nominal, an Austin-based startup building AI platforms for complex hardware engineering, raised $240 million in Series C funding on Monday at a $3 billion valuation—triple its $1 billion valuation from eight months prior.
Lightspeed Venture Partners led the round, with Insight Partners co-leading. The raise follows a $155 million Series B extension in March that was initiated by investors as a preemptive deal, led by Trae Stephens at Founders Fund.
Nominal's platform simulates and tests hardware for aerospace, nuclear, and industrial applications. The company counts 80 commercial and government organizations as customers, including defense contractor Anduril, which Stephens co-founded.
The valuation jump reflects hard validation. In October, the U.S. Air Force designated Nominal for a $71.2 million Strategic Funding Increase investment, a program that requires matching funds from private investors—a signal of external confidence in the technology.
CEO and co-founder Cameron McCord, a former U.S. Navy submarine officer and Anduril veteran, bridges the startup's customer and investor base. Beyond Lightspeed and Insight, backers include Sequoia, General Catalyst, and Lux Capital.
The funding round reflects intensifying competition for AI applications in capital-intensive industries. Hardware simulation has become a critical efficiency lever for defense and aerospace, where physical prototyping cycles are measured in years and billions in spend. Nominal's platform accelerates that cycle by orders of magnitude—a genuine economic moat in sectors where time and iteration are existential constraints.
