Defense startups overestimate dual use
The biggest mistake defense startups make
True dual use is rare because the same product has to solve the same job in both markets, not just share underlying technology. That is why software and autonomy categories show up more often than specialized defense hardware. A routing engine can help an airline plan around storms, and help a military planner move aircraft and supplies. A ground autonomy stack can back a missile trailer or a yard truck with the same sensors, controls, and safety logic. Small armed drones and other narrow mission systems usually break here, because the commercial buyer does not need the military version of the problem.

Airspace Intelligence is a clean example of dual use working from a commercial wedge. It sells software to large airlines for route planning and network operations, then extends that same decision software into government and defense settings where the core problem is still moving aircraft safely and efficiently through constrained airspace.
-
Ground autonomy can work when the product is a reusable driving stack, not a one off vehicle program. Forterra positions AutoDrive as the same autonomy layer across defense vehicles and industrial trucks, and has paired Marine Corps production work with commercial logistics deployments. The overlap is in off road and closed site driving, where both customers need rugged self driving more than consumer grade road autonomy.
-
The limiting factor is procurement and workflow fit, not technical ambition alone. Defense buyers often want integration, ruggedization, and operation in GPS denied or contested environments, while commercial buyers want faster payback and lower labor cost. Dual use works when one product can absorb those differences without turning into two separate companies.
The next wave of defense startups will keep splitting into two groups. One group will build broad software and autonomy products that can cross into commercial markets and compound faster. The other will build narrow weapons or mission specific systems that can become large, but only through defense budgets and programs of record. The strategic advantage will sit with companies whose product can travel across both without being rebuilt each time.
