Perseus Defense
Perseus Defense is a YC S25 aerospace and defense startup building low-cost, man-portable guided micro-missiles to shoot down small drones. Its Harpe interceptor targets Group 1 and Group 2 drones at a claimed cost of under $10,000 per shot - roughly a 20x reduction versus existing systems - closing the cost gap where a $500 drone can threaten multi-million-dollar assets. Founded by ex-NASA aerospace engineer Jason Cornelius and ex-Boeing autonomy lead Steve Messinger, the company is building an affordable, mass-producible 'Iron Dome for drones' for U.S. defense and homeland security customers.
