Kelluu

Kelluu is a Finnish deeptech company that designs, manufactures, and operates autonomous hydrogen-powered airships. Their unmanned fleet provides continuous monitoring and high-resolution data collection across vast and remote areas, enabling earlier threat detection and more efficient operations. The airships are designed for silent, low-emission operation in challenging environments and address a critical gap between satellites and drones by offering long-endurance persistence (exceeding 12 hours) with high-precision sensing. Kelluu's technology supports both defense and civilian applications, including forestry monitoring, meteorology, smart-city sensing, and the protection of critical infrastructure. They are also developing geospatial foundation models for the physical environment through Kelluu AI Labs.
