Arlo Industries debuts Mentat, a passive sensor mesh to track drones and missiles without radar
In a YC Launch post, Arlo Industries says its distributed passive network tracks low-altitude drones and cruise missiles in 3D without emitting, following field tests with Ukrainian units and early partnerships in Europe and the U.S.

Why it matters
Low-altitude drones are overwhelming legacy radar-centric air defense. If a passive, distributed mesh like Mentat works at scale, it could shift cost and survivability curves for militaries and critical infrastructure.
In a YC Launch post, Arlo Industries founder Deo Arlo introduced Mentat, a passive, distributed sensor network the company says tracks low-altitude drones and cruise missiles in 3D without emitting, positioning it as a scalable alternative to traditional radar. He framed Mentat as the sensing layer for counter-UAS and interceptor systems and shared a short demo video on Arlo Industries and YouTube.
The company says Mentat ties many low-cost nodes into a mesh that improves accuracy on smaller targets while avoiding the high cost and targetability of large emitting radars. "Drone detection is our wedge, not our ceiling. The real innovation isn't in any single sensor, it's in the network that ties it all together," Arlo wrote, adding that the goal is a resilient frontline sensing and communications layer.
Deo Arlo anchored the effort in personal experience: 6+ years in Israel observing systems like Iron Dome and a Shahed drone exploding near his apartment, then months in Ukraine and across Eastern Europe working with operators to validate in live conflict settings. According to the post, Arlo Industries has run active technology demonstrations with Ukrainian military units and has relationships in the U.S., Ukraine, Finland, and Estonia. The team includes a PhD in drones/autonomy and military domain experts.
The company argues the timing is right as swarms of cheap drones and cruise missiles exploit radar coverage gaps, while edge compute and passive optical sensing make a different architecture viable. Arlo Industries is hiring across optics, signal processing, long-range comms, mesh networking, and off-grid embedded systems, per the announcement.
