Kelluu designs, manufactures, and operates autonomous hydrogen-powered airships that collect centimeter-accurate aerial data for defence, infrastructure, and environmental monitoring.
Kelluu says satellites lack the resolution and drones lack the endurance for persistent monitoring, while its airships can fly for more than 12 hours and deliver centimeter-level data in Arctic and GNSS-denied conditions. Its €15 million Series A led by the NATO Innovation Fund is intended to scale the fleet, international growth, and AI capabilities, building on Terrafame operations and NATO exercises as early commercial and defence traction.
