Defense tech boom masks 'Valley of Death' for startups, says XYZ VC founder
While the U.S. government proposes a 40 per cent defence budget increase and valuations for Anduril and Mach Industries surge, many new entrants struggle to transition from early-stage funding to full-scale production.

The defence technology sector is currently experiencing a significant surge in capital inflow, driven by proposed increases in U.S. government spending and rising valuations for key industry players. Ross Fubini, founder and managing partner of XYZ Venture Capital, discussed the current market dynamics on TechCrunch’s Equity podcast, noting that while the environment is "red hot," the path to long-term viability remains fraught with challenges for new entrants.
Fubini, who was an early investor in Anduril, highlighted that the U.S. government is proposing a 40 per cent increase in its defence budget. This financial backdrop has attracted a wave of new startups eager to secure government contracts. However, he cautioned that significant capital does not guarantee success, as many firms struggle to navigate the critical phase between securing initial prototype contracts and achieving real-world production deals.
This transitional phase is often referred to by industry insiders as the "Valley of Death." According to Fubini, most startups attempting to enter the defence market will fail to secure the necessary funding or contracts to cross this gap. The distinction between those that survive and those that do not lies in their ability to move beyond early-stage development and demonstrate scalable production capabilities to government buyers.
Recent market movements underscore the high stakes and potential rewards in this sector. Anduril and Mach Industries have recently seen their valuations double and quadruple, respectively. These gains reflect the intense competition and capital interest in established players, yet they also highlight the disparity between successful incumbents and the broader field of startups vying for a share of the expanding defence budget.
XYZ Venture Capital, which Fubini founded and which is built on a Palantir alumni network, is currently approaching $2 billion in assets under management. The firm’s focus on identifying startups that can successfully navigate the transition from prototype to production positions it to capitalise on the sector’s growth. Fubini’s analysis on the Equity podcast, interviewed by Rebecca Bellan, provides a framework for understanding what separates the survivors in this increasingly competitive landscape.
The discussion on TechCrunch’s Equity podcast explores the specific criteria that determine which startups will win government contracts. As the defence tech sector continues to attract significant investment, the ability to bridge the gap between early-stage innovation and large-scale government procurement will likely remain the primary determinant of success for new firms.
