Artificial intelligence enters hardware engineering

Hardware engineering is undergoing a silent but profound transformation. For decades, testing and validating complex systems — from aircraft engines to nuclear reactors — has relied on engineers manually connecting data from scattered instruments, interpreting results based on institutional memory, and solving problems that often had already been solved but never documented centrally. Nominal, a startup based in Austin, Texas, wants to change that. On Monday (November 9), it announced a US$ 240 million Series C round, reaching a US$ 3 billion valuation — triple the US$ 1 billion it achieved just eight months ago, in March.

The company was founded four years ago by Cameron McCord, a former U.S. Navy officer and former Anduril Industries employee, the defense company co-founded by Palmer Luckey. What began as a tool to help engineering teams compare test data with expected behavior has evolved into something much larger: a complete hardware intelligence platform with four interconnected layers, designed to cover the entire lifecycle of complex machines.

The problem Nominal solves

Getting an unexpected test result in a high-stakes engineering environment is, in practice, an investigative problem. A sensor emits a reading outside the curve. The engineer needs to figure out why. To do that, they must cross-reference data from multiple measurement instruments, simulations, internal records, and decisions made months earlier. Often, the answer already exists within the organization — a senior engineer has seen this problem before — but there is no systematic mechanism to connect the question to knowledge already acquired.

Nominal proposes a four-layer platform called the Hardware Intelligence Platform. The Connected Control layer connects software to physical hardware and test systems, allowing teams to command equipment and capture data at the source. The Connected Data layer aggregates information from different sources — sensors, simulations, engineering files — into a unified repository that preserves the engineering context behind every reading. The Connected Intelligence layer applies AI tools to help engineers analyze that data, identify patterns, and make recommendations. Finally, the Connected Applications layer offers specific tools for day-to-day tasks: requirements verification, planning, scheduling, and fleet maintenance.

The company's differentiator, it says, isn't having more capable AI models — it's building the data infrastructure and context that allows AI to operate in the physical world, where "physics gets a vote," as McCord puts it in his blog.

What investors are betting on

The Series C round was led by Lightspeed Venture Partners, with Insight Partners co-leading. Other major investors include Lux Capital, Sequoia, General Catalyst, Founders Fund, Avenir, Salesforce Ventures, M13, Lockheed Martin Ventures, Red Glass Ventures, PSP Growth, and Deployment Capital.

The investor portfolio says a lot about the thesis behind the bet. The presence of Palmer Luckey (via Founders Fund) and Anduril — which is one of Nominal's key customers, with more than 300 engineers using the platform on its programs — indicates the company is already deeply embedded in the high-level defense ecosystem. Lockheed Martin Ventures confirms that major government contractors already trust the platform.

The company claims to have 80 commercial and government organizations as customers, including five of the seven largest U.S. defense contractors. In October, it was selected by the U.S. Air Force for a US$ 71.2 million investment in the STRATFI (Strategic Funding Increase) program, a program that requires matching capital from outside investors — an additional government validation.

Why now?

Nominal's answer to "why now?" is the same as what motivates virtually every infrastructure AI startup in 2026: AI models have finally reached the technical maturity to be applied to complex domains, but the data infrastructure needed to make this work in the physical world is still in its primitive stages. Nominal built that infrastructure over the past four years — and the moment to scale has arrived.

"In the next decade, companies that effectively integrate AI into engineering workflows will have a real competitive advantage," said McCord. This isn't empty rhetoric. In the use cases Nominal has documented, tasks that once took hours — such as production test data analysis, design requirements verification, anomaly detection in aerospace components — are now executed in minutes by the platform, with engineers maintaining final control of the decisions.

The challenge ahead is ambitious: extend this approach to more workflows, more industries, and more regions worldwide while preserving the traceability and engineer control that are essential in high-consequence environments. If Nominal pulls this off, it won't just be building the "Microsoft Office of hardware engineering" — it will be redefining how the physical world is designed, built, and maintained.
