Rebellion Defense, the Eric Schmidt-backed developer of AI defense tech, raises $150M led by Insight and Venrock at a $1B pre-money valuation

Context & Ripple Effects
Rebellion Defense had been flying under the radar before this round: an American Prospect profile earlier in 2021 described it as an obscure startup building AI and infosec applications for the US government, with Eric Schmidt among its backers. The $150M round led by Insight Partners and Venrock at a $1B pre-money valuation converts that obscurity into a defense-AI unicorn overnight.
The reason this raise is worth revisiting is what came after it: by late 2023, Forbes reported the company was struggling to survive after failing to win a US Department of Defense contract, losing its founders and shutting its UK arm. The 2021 valuation now reads less like a milestone than the peak of a funding cycle that outpaced the company's ability to convert venture capital into government revenue.
First-order effects
- Insight Partners and Venrock put Rebellion Defense on the unicorn list at a $1B pre-money valuation, making Eric Schmidt's bet one of the most visible private marks in AI defense tech at the time.
Second-order effects
- The company's later collapse after losing its DOD contract exposed how dependent these valuations were on a single customer, pressuring later defense-AI startups like Allen Control Systems — whose $200M Series B came years later — to prove procurement traction alongside headline rounds.
Third-order effects
- The pattern suggests defense-AI equity values are ultimately set by government contract wins rather than fundraising momentum, a discipline the sector absorbed only after early unicorns like Rebellion Defense demonstrated what happens when the DOD says no.
The trend: AI defense startups are learning that the state-compatible lab's valuation floor is set by procurement outcomes, not investor enthusiasm.
