Ross Fubini, who wrote Anduril's first check, sees defense technology as a red-hot sector amid a proposed 40% U.S. defense budget increase. Anduril and Mach Industries have doubled and quadrupled their valuations respectively, but Fubini warns most startups will struggle to survive the Valley of Death between prototype and production deals.

As founder and managing partner of XYZ Venture Capital approaching $2 billion AUM, Fubini identifies key success factors for defense startups. Ukraine and Iran have become live testing grounds, while sovereign defense tech ecosystems are emerging globally. He emphasizes that autonomous logistics represents the real moat in defense technology, not just the flashy prototypes.

Fubini's next investment focus includes AI-driven U.S. manufacturing and government software for health and human services. His insights reveal a shift toward sustainable defense solutions beyond initial prototypes, addressing the sustainment problem that many startups overlook. The defense tech landscape requires both innovation and practical implementation to capture government contracts.
