Drones that clear clouds over solar farms and weaken hurricanes. Meteoric is building drones that clear clouds and weaken storms over critical infrastructure like solar farms, airports, defence assets, and ultimately weaken hurricanes.
Building drone swarms that hunt drone operators. We build LEGION, a drone swarm that identifies, geolocates, and tracks every emitter on the battlefield using the enemy’s own radio signals. LEGION enables our warfighters to precisely track previously obscured targets like jammers, command posts, and drone operators so they can proactively respond to threats instead of reacting to them.
Mass-produced AI strike systems and Counter-UAS. Isengard Industries is not another drone company. We build sovereign production: the means for allied nations to make precision-strike and counter-drone systems by the thousand, on their own soil, at a fraction of what the primes charge. We call it Weapons of Mass Production. The Arsenal of Democracy, rebuilt for the drone age. More to come, and only where it helps. You know how to reach us.
Track drones and missiles without radars - Accurate, Passive, Scalable. Arlo Industries is building a network of sensors that precisely tracks stealthy drones and aerial threats better than radars. This capability does not exist yet because traditional radars are built on past war doctrines designed to protect single, centralised assets. Modern warfare, however, demands wide-area, persistent coverage that is both passive and economically scalable. By utilising a mesh architecture, Arlo Industries unlocks unprecedented asymmetric economics. The network is fundamentally built to scale: the cost of adding sensors grows linearly, but the tracking accuracy increases exponentially, delivering highly resilient, persistent coverage for a fraction of the cost of legacy systems. Deo founded Arlo Industries after spending over 6 years in the Israeli defence ecosystem, where he lived through multipl
Counter Drone Systems. $1.6m sales. We delivered for the DoW.. We have sold $1.6m of systems to the DoW. Multiple systems delivered to the DoW. Our first product - EDDA - is a counter drone system - small, low power, low cost fully autonomous-capable. It's designed to be used on vehicles, bases, or carried - to stop group 1 suicide drones. We have multiple contracts, sales, etc. We have 3 more products with demand in various stages of development. More details at https://9mothers.com
Autonomous Drones for Earth Observation. Voltair is building the world's first globally distributed network of autonomous drones for Earth observation. Power utilities are the perfect first customer. Aging infrastructure and extreme weather drive the need for millimeter-scale inspection data on the power grid. Utilities spend tens of billions of dollars every year just looking at their own equipment. Autonomous drone fleets will enable utilities to inspect 7 million miles of infrastructure more frequently, quickly, and accurately. Our long-range, weatherized flying robots work with charging pads installed directly on utility poles. Each new pad unlocks 1000 square miles of coverage. With a charging network deployed on the power grid, we can serve existing multi-billion dollar data markets in road, rail and telecom inspection at 10x lower prices while enabling entirely new applications in
Software for enterprise energy procurement.. Condor helps large electricity consumers - C&I and data centers - cut electricity costs by helping the grid. We are former electricity traders and energy physicists. We build an AI-powered software that our clients use to optimize their energy procurement - making sure they always have access to cheap & reliable power.
Technology to detect and track small drones. 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.
