This Startup Helps Test Planes and Satellites, and It Just Tripled in Value
A company called Nominal just raised $240 million in its Series C round. The deal values it at $3 billion, which is about three times what it was worth back in March. Nominal makes software for engineers who test machines like planes and satellites. One single test can make a mountain of numbers, and Nominal helps engineers keep all of it in one place and read it faster.
Who put money into Nominal?
Lightspeed Venture Partners led the round, and Insight Partners co-led it. Sequoia, Founders Fund, and Lockheed Martin Ventures joined in too. Back in March, Nominal raised $80 million at a $1 billion value, led by Founders Fund.
How does the software help?
Picture a race car with hundreds of sensors. Each one sends numbers every single second, and engineers have to read all of them to know if the car is working well. Nominal gathers all that test data in one spot. It also has an AI helper called Nominal Analyst. The company says it points back to the evidence for each answer, so engineers can double-check the work.
Which claims can we check?
Honestly, not many. Nominal says its revenue has more than tripled this year, but there are no exact numbers or method in the reports we read, so we can’t check that. It also says more than 80 companies and government groups use its software, including five of the seven biggest defence contractors. It says Anduril has over 300 engineers on it, and that some work that used to take five to six hours now runs in near real time. It also says Hermeus cut its data review wait by 80%. All of that comes from Nominal, and we found no outside proof.
The one thing with a clearer paper trail is the US Air Force picking Nominal for a $71.2 million program called STRATFI. Of that, $41.2 million is government money and $30 million is Nominal’s own. It supports testing of uncrewed jets that fly next to piloted fighters.
Why are investors so excited?
Nominal isn’t the only one getting attention. PitchBook data reported by Tectonic Defense shows $35.6 billion went into defence and defence-related startups in the first half of 2026, which is a record pace. The Next Web says Bloomberg linked Nominal’s growth to a boom in defence spending. More new machines means more tests, so that might explain why investors like it.
Reasons to be careful
A $3 billion value is just what investors are willing to pay today. It doesn’t prove the company will succeed later. ClearanceJobs points out that the defence funding boom isn’t shared evenly. Nominal’s growth is tied to defence spending, so if that slows down, it could hurt. That last part is our own opinion, though. Nominal also says AI alone won’t build better machines, because “physics gets a vote.”
What comes next?
Nominal says it’ll spend the money on more AI agents for jobs like planning, scheduling, and checking machine health. It also wants to move into new industries and buy more companies. It already bought Fid Labs in April 2026, a startup that builds AI agents for hardware work. The Next Web says it also bought Pull Systems, which opens the door to the car industry.
For now, Nominal looks like a fast-growing company in a really hot market. But the real proof will come from independent results and actual customers, not from funding news alone.
