Relying only on technical founders
The biggest mistake defense startups make
The real constraint in defense startups is not finding a clever product idea, it is assembling a team that can turn prototypes into programs the government can actually buy. That means technical founders alone are rarely enough. Companies need operators who understand procurement, safety certification, budgeting, pricing, field testing, and how to climb from a $100,000 pilot to a multiyear program without getting trapped in custom work.

Anduril worked because it combined an unusually strong founding bench with a playbook for moving from fast prototypes, to paid range demos, to scaled products like towers and counter drone systems. Its first meaningful steps were small contracts, then a $12.5 million Marine Corps award, then a $1 billion program.

Forterra describes the same pattern more bluntly. A venture scale defense company needs multiple outlets for one core product, across defense programs or into commercial markets, because any single DoD niche is smaller and slower than it looks from the top line Pentagon budget.
-
That is why defense is super team biased. The work includes software, hardware, safety cases, manufacturing, contract structure, and customer education. A two person team can build a demo, but building something the DoD will trust, fund, field, and reorder usually takes a much broader operating team.
The next wave of winners will look less like garage startups and more like trained teams spinning out of places like Anduril, Palantir, SpaceX, and Forterra. As more people learn the procurement and deployment playbook, defense venture outcomes should broaden beyond one-off stars into a deeper bench of companies with narrower products, clearer markets, and faster paths to scale.
