Nominal Secures $240M Series C at $3B Valuation for AI Expansion

Nominal announced on November 9, 2026, that it had raised $240 million in a Series C round at a $3 billion valuation. Lightspeed Venture Partners led the financing and Insight Partners co-led it, providing capital to expand Nominal’s AI platform for hardware engineering.

The funding will support deeper products for engineers and engineering enterprises, expansion into new industries and regions, and strategic acquisitions. Lux Capital, Sequoia, General Catalyst, Founders Fund, Lockheed Martin Ventures, Salesforce Ventures and DE Shaw Ventures are among the other investors named in the announcement.

From Test Data to Engineering Intelligence

A companion platform post says Nominal spent four years assembling the data infrastructure, equipment connections and contextual information on which its platform depends. The company began by helping hardware teams work with test data: comparing expected behavior with measured results, investigating differences and deciding what to do next. Its broader argument is that AI needs access to that evidence and context instead of producing answers from isolated prompts.

That foundation is meant to address fragmentation. Engineering evidence sits across instruments, simulations, files, internal tools and teams, so interpreting an unexpected result can require connecting a sensor reading to a hardware configuration, an earlier experiment and a decision made months earlier. Nominal’s response is a four-layer Hardware Intelligence Platform designed to bring those inputs together without stripping away their context.

Connected Control links the software to physical hardware and test systems, allowing teams to command equipment and capture data at its source. Data Infrastructure gives signals, files, configurations and documents a common structure while preserving what measurements represent, which systems produced them and how they relate to earlier work. Together, those layers supply the organized evidence used by the platform’s AI components.

AI Agents Built on Inspectable Evidence

The Intelligence Layer connects models and agents to engineering context, tools and workflows. It enables systems to investigate questions, run analyses, compare results and assemble evidence that engineers can inspect. Nominal describes Nominal Analyst as its first purpose-built AI agent; it investigates engineering data and runs complex analyses, with answers traceable to the underlying evidence. Engineers retain control over decisions, reviews and approvals.

Engineering Applications extend the platform across development, testing, manufacturing and operations. Through Nominal for Developers, customers can connect existing tools and build custom applications, workflows and agents on the same foundation. Deployment options cover cloud and on-premises infrastructure, air-gapped environments and edge devices.

Reported Adoption and Expansion Plans

Nominal reports that more than 80 commercial and government organizations use the platform, including five of the seven largest defense contractors. Its users span aerospace, defense, robotics, energy and advanced manufacturing, giving the company an established base for the broader lifecycle products it plans to develop.

That roadmap extends beyond test analysis. Nominal is developing agents and applications for requirements verification, planning, scheduling and fleet health across a machine’s lifecycle. Co-founder and CEO Cameron McCord said the goal is to put decades of accumulated engineering knowledge to work while leaving engineers in command.

The financing ties Nominal’s growth plans to a demanding proposition: AI must reach physical systems, work from structured engineering evidence and expose the basis for its answers. Extending that approach into more workflows, industries and regions will test whether the company can broaden its platform while preserving the traceability and engineer control required for high-consequence work.
