Milliray

Milliray is a Y Combinator-backed company that technology to detect and track small drones. The company participated in the Winter 2026 batch of Y Combinator.

We make radars that can see small drones.

As drones evolve faster than air defenses, detection has fallen behind. Even $50 drones now present a major threat to airports, critical infrastructure, and front-line defense.

We solve this by building high-frequency radar systems, designed from the ground up to detect even the most challenging low-signature targets. This allows us to identify and track nano drones like no other solution, letting you know what's truly in your airspace.

Milliray was part of Y Combinator's Winter 2026 cohort, has a team of approximately 3 employees, and is actively operating.
