Silicon Valley’s Hyped $1 Billion Military AI Startup’s Drastic Decline


During the all-hands meeting held in March, expectations ran high among hundreds of Rebellion Defense employees. The company had been eagerly anticipating positive news regarding a significant military contract that had been in development for months. Assurances from the leadership, indicating the near-certain acquisition of a substantial deal with the Department of Defense, buoyed hopes. This potential agreement, estimated to be worth tens of millions of dollars, held the promise of unlocking fresh funding for the $1 billion AI startup, reinforcing its position as a prominent ally of the Pentagon in the race to advance AI technology for military use.

Rebellion had actively recruited numerous engineers and specialists to contribute to the development of their flagship product: a tactical threat awareness tool (TTA) infused with AI capabilities aimed at making critical battlefield decisions. According to reliable sources, this tool, pivotal to Rebellion’s mission of revolutionizing warfare through sophisticated software, was being pitched to the Under Secretary of Defense for Research and Engineering. The company’s vision had attracted substantial investments from notable figures like former Google CEO Eric Schmidt and media tycoon James Murdoch.

However, when CEO Chris Lynch, a tech entrepreneur turned Pentagon executive, addressed the staff at Rebellion’s Washington, D.C. headquarters in March, the news he conveyed was grim. Contrary to expectations, the contract had not been secured. Subsequently, around 90 employees, including recent hires, were laid off the following month. By September, Lynch had departed, and Rebellion’s operations in the U.K. had ceased as well.


Rebellion’s spokesperson, Gia DeHart, explained to Forbes that the contract in question had still not been awarded, framing it as an instance highlighting the challenges startups encounter when attempting to engage with the U.S. Department of Defense in implementing innovative solutions.

The swift rise of Rebellion since its launch in 2019 was marked by a lack of tangible evidence. Despite being valued at $1 billion, the company lacked a substantial track record as a government contractor and had struggled to establish a significant presence in the commercial market. Even its flagship product, Nova, failed to gain widespread adoption. Former employees expressed surprise at the absence of a core product within the company.

The company projected an image of success and influence, boasting frequent visits from military figures to its impressive offices in D.C. and London. However, interviews with ex-employees and advisors, along with contract reviews, suggest that Rebellion thrived more on aspirational hype driven by investors than concrete achievements.

Chris Lynch, as CEO and co-founder, brought an outsider’s boldness to the endeavor of integrating AI into the military-industrial complex. However, his departure was reportedly orchestrated by a board dissatisfied with his exaggerated financial forecasts and inability to secure crucial contracts, despite painting optimistic pictures for 2023 to employees and the board.

Despite spending significant sums on lobbying the federal government for AI-related matters, Rebellion’s publicly disclosed contracts amounted to $7.2 million in 2023, a modest increase from $6.2 million in 2022. The company declined to provide specifics about its government deals.

In response to inquiries about revenue, contracts, and management issues, Rebellion opted not to divulge financial details or comment on personnel concerns. They only highlighted a reported 50% surge in their annual contract value this year and emphasized their adaptability to ensure long-term sustainability.

The newly appointed CEO, Ben FitzGerald, acknowledged the management challenges faced by the company but asserted that Rebellion had restructured and assembled an exceptional team.

As for Chris Lynch, although he remains one of the company’s major shareholders, he seems focused on his future in the defense sector. He emphasized the importance of technology in empowering the military against adversaries, signaling a continued interest in this arena.
