Nominal, an Austin-based startup that sells artificial-intelligence software for testing hardware, said this week it has raised 240 million dollars in a Series C round that values the company at 3 billion dollars, tripling its valuation just eight months after its previous raise. Lightspeed Venture Partners led the round, with Insight Partners co-leading, and prior backers including Sequoia Capital, Lux Capital, Founders Fund and Lockheed Martin Ventures also participating.
The jump reflects the pace at which investors have been pricing companies selling software and AI tools into the defense and advanced-manufacturing sectors. Nominal's previous round, an 80 million dollar raise led by Founders Fund in March, valued the company at 1 billion dollars; some trackers describe that earlier deal as an extension of its Series B rather than a standalone round, reflecting how quickly the company returned to market for fresh capital.
Betting on AI inside hardware testing
Nominal's platform is built to ingest and analyze the mountains of sensor and test data generated when hardware makers, from satellite builders to defense contractors, put physical products through engineering trials. The company says its software now embeds AI agents directly into that testing workflow, aiming to cut the time engineers spend manually reviewing logs and flagging anomalies. Nominal has said five of the seven largest U.S. defense contractors now use its products, a customer base that has made the company a bellwether for AI adoption inside an industry traditionally slower to embrace new software.
The round arrives amid a broader surge in venture financing for hardware-adjacent AI startups. Tracking data compiled by Fundz shows 25 U.S. companies closed named venture rounds between November 2 and November 8 alone, raising a combined 2.88 billion dollars, led by satellite-ground-station startup Northwood Space's 375 million dollar Series C. Investors in that wave have increasingly favored companies that pair AI software with physical or defense-adjacent products, a category that includes Nominal, Northwood and a growing list of similarly positioned startups.
Lockheed Martin Ventures' continued participation in Nominal's funding rounds points to a deepening pattern of large defense contractors taking direct equity stakes in the software vendors supplying their engineering pipelines, rather than relying solely on traditional procurement contracts. Nominal has not disclosed revenue figures or said how it plans to deploy the new capital beyond broadening its engineering and sales teams, but the valuation leap signals that investors are pricing in continued expansion of AI tools across defense manufacturing, a sector that has drawn rising venture interest as traditional contractors modernize decades-old testing infrastructure.
