About Tonner Drones
Tonner Drones is the successor to Delta Drone and combines a small operating technology portfolio with active investment management. Its principal robotics product is Countbot, developed with GEODIS to automate warehouse stock counts using a ground platform, stabilized aerial scanning and inventory software. The company also holds Inhibitor recoil-stabilisation IP for armed drones.
Management has restructured the listed company around an asset-light model: R&D and commercialisation remain in France, but manufacturing is expected to rely on partners. Tonner also manages stakes in French drone companies including Elistair, Donecle and Diodon and may generate revenue through equity disposals, royalties or patent transactions as well as product sales.
