€7.1m · Seed · Defence, Space · Paris, France
Paris-based Gallium Defense has raised a €7.1m Seed round co-led by Keen Venture Partners and 360 Capital, with Omnes Capital and Polytechnique Ventures participating. The investor-hosted announcement says the funding will move its first drone-detection radars into production, expand the team, train embedded AI models and support demonstrations with civil and military operators.
Coverage economics shape the radar design
Gallium is developing the GDS-10, a software-defined X-band AESA radar for armed forces and critical infrastructure operators. The company says it is designed to detect small and first-person-view drones at up to 10 kilometres, track multiple targets and connect to existing command systems through open NATO-standard interfaces. Civil and military variants use the same underlying platform.
The commercial thesis is as much about unit economics as detection performance. Protecting many dispersed sites requires sensors that can be manufactured and deployed in volume, not only a small number of high-end systems. Gallium is using commercial components, embedded computing and software updates to lower the cost of each installation. That could widen the addressable market, but the advantage has to survive manufacturing, field conditions and integration into customers’ existing security systems.
Field trials are the bridge to first orders
Gallium was founded in Paris in April 2026 and says it moved the GDS-10 into open-air trials within months of closing the round. Orders are expected to open in the first quarter of 2027. The Seed capital therefore finances an industrial and operational proof point: repeatable production and credible demonstrations for operators. If deployments generate useful detection data, software-defined models can improve across the installed fleet, giving the hardware business a continuing product-development loop after shipment.
