Kelluu

Kelluu operates the world's largest autonomous airship fleet, providing persistent aerial data collection for defense, critical infrastructure monitoring, and environmental intelligence. The company's hydrogen-powered airships deliver 12-hour continuous flight times with 1-centimeter resolution imagery, filling the gap between satellites (which lack accuracy) and drones (which lack persistence). Kelluu turns aerial data into digital twins, live monitoring feeds, and change detection analysis, enabling organizations to maintain up-to-date situational awareness of complex environments. The airships use a patented hydrogen-safe structure, carry up to 6 kg of sensor payload, operate autonomously without on-site pilots, and are silent enough for populated areas with Europe-wide regulatory compliance. Kelluu serves three primary domains: defense (autonomous persistent situational awareness), critical infrastructure (wide-area monitoring and early risk detection), and environmental intelligence (detecting threats like bark beetle outbreaks before they become disasters). The company manufactures its own airships at the northernmost airship factory in the world, offering a complete aerial monitoring ecosystem as a service. Founded in 2018 and headquartered in Joensuu, Finland, Kelluu has raised approximately $17.6 million in a Series A round backed by Redstone, NIF, Keen Venture Partners, Tesi, and Gungnir Capital.
