Nominal, a four-year-old Austin startup building an AI platform for engineering and testing complex hardware, has raised a $240 million Series C at a $3 billion valuation. The round, announced on 9 November, was led by Lightspeed Venture Partners and co-led by Insight Partners. It triples the company’s valuation from $1 billion in March, when it raised a $155 million Series B extension.
What Nominal does
Nominal calls itself the Hardware Intelligence Platform. It connects hardware test data with the engineering context behind it — the conditions, decisions and history that give the data meaning — so engineers can understand complex systems, investigate problems and make better decisions. AI agents work from the same foundation, analysing information and surfacing knowledge that once took hours of investigation.
The company’s first AI agent, Nominal Analyst, investigates engineering data and runs complex analyses, with answers traceable to the underlying evidence. Engineers keep control of the decisions, reviews and approvals that matter. The platform works with the tools teams already use, through SQL, APIs and MCP, and supports cloud, on-premises, air-gapped and edge deployments.
The customers and the numbers
More than 80 commercial and government organisations use Nominal, including five of the seven largest defence contractors. At Anduril, more than 300 engineers rely on it, and analysis that once took five to six hours now happens in near real time. At HII, it cut production test steps by about half; at Hermeus, it cut data review time by 80%.
The US Air Force recently selected Nominal for a $71.2 million Strategic Funding Increase, known as STRATFI, to support Collaborative Combat Aircraft capability development. The award, which requires matching funds from outside the Air Force, is the latest step for a company that gained early traction in defence, where engineering rigour and security requirements are exceptionally high.
Where the money goes
The funding will support deeper products for engineers and engineering enterprises. Nominal is developing agents and applications for work across a machine’s lifecycle, from requirements verification and planning to scheduling and fleet health. The company will also expand into new industries and regions, including through strategic acquisitions.
This year, Nominal acquired Fid Labs, whose team is developing its agents, and Pull Systems, extending the platform into automotive. The investor list for the Series C runs deep: Lux Capital, Sequoia, General Catalyst, Founders Fund, Avenir, Salesforce Ventures, M13, Lockheed Martin Ventures, Red Glass Ventures, PSP Growth and Deployment Capital joined the round.
Why It Matters
Hardware engineering is where AI meets the physical world, and it has been slow to arrive. Aircraft, satellites, nuclear reactors and smart factories are built on decades of hard-won knowledge that lives in individual engineers’ heads and in fragmented legacy systems. A platform that connects that knowledge to data, and lets AI agents work from it, attacks the bottleneck directly.
The valuation tells the same story as the customer list. Tripling to $3 billion in eight months, with five of the seven largest defence contractors as customers, is not a bet on a demo. It is a bet that the companies building the world’s most advanced machines will pay for the platform that organises how they build them.
Our Read
The read is that Nominal is riding two waves: the physical-AI wave, as intelligence moves from software into machines, and the defence-tech wave, as governments pour money into rearmament and reshoring. A platform that serves both — defence contractors and the Air Force on one side, robotics and automotive on the other — is positioned to catch funding from both.
The comparison that counts is with the rest of this year’s AI funding rounds. Sand.ai raised $200 million to become a unicorn, and Axon put $1.2 billion into Skydio — but Nominal’s round is larger than Sand.ai’s and, at $3 billion, values a four-year-old company at the level of Serval’s Series C. The market is paying up for hardware intelligence.
For Nominal, the test is delivery. Revenue has more than tripled since the start of 2026, the company says, and the Air Force award and the Anduril deployment are the proof points to watch. If the platform keeps cutting analysis from hours to minutes, the $3 billion valuation will look cheap. If it stalls, it looks like a peak.
Background
Defence technology has become one of the hottest corners of AI funding. Disruptive is betting $10 billion on ten AI and defence winners, and Anduril and Qualcomm are building a laptop made in America. Nominal, whose customers include Anduril and five of the seven largest defence contractors, sits squarely in that flow.
