Deterrence over parity in defense

a16z General Partner David Ulevitch joins Sourcery to break down the real state of American Dynamism, their $600M fund, across defense, energy, mining, robotics, manufacturing, public safety, and national security.

We discuss America’s supply-chain exposure to China, why deterrence—not parity—defines the future of U.S. defense, and how new companies are rebuilding core capabilities in nuclear, missiles, autonomy, grid reliability, materials, mining, and industrial operations.

David highlights key a16z portfolio companies including Anduril, Radiant Nuclear, Base Power, Exowatt, Apex, Skydio, Flock, Long Eye, and Mariana Minerals, and shares why the best founders are magnetic attractors of capital and talent.

We also dive into Anduril’s authenticity-first marketing philosophy (“no renders” - Palmer Luckey), the “Don’t Work at Anduril” campaign led by Snap Alumn Jeff Miller, the importance of real test footage, and why mission-driven cultures are fueling the next generation of frontier companies.

A broad, detailed look at the future of American reindustrialization and the companies shaping it.
