Perseus Defense

Perseus Defense (YC S25) - Building America's Golden Dome for Drones
Drones that cost $500 are destroying $100M assets—and 70–80% of battlefield casualties now come from drone strikes. Today’s counter-drone systems fail where it matters most: cost, scale, and rapid effectiveness.
At Perseus Defense, we’re building 15″ missiles that detect, identify, and neutralize hostile drones—two orders of magnitude cheaper than current defense options.

Why Now? Our work directly responds to the White House Executive Orders on Unleashing American Drone Dominance and Restoring American Airspace Sovereignty. We've interviewed +100 end-users from boots on the ground up to the Pentagon. The Navy Seals are interested in our dismounted variant, while Army and Marine Core soldiers like the light-tactical vehicle mounted solution.
