Kelluu
Kelluu designs, manufactures and operates hydrogen-powered autonomous airships and claims the world's largest autonomous airship fleet, sold as 'airship-as-a-service' for persistent ISR over defence, border-security, critical-infrastructure and environmental customers. The fleet has logged over 50,000 km including 12-hour Arctic missions, operates down to -33C and flies through sustained GNSS jamming. Started in civilian applications (forestry analytics in Sundsvall, digital twins and safety monitoring for mining company Terrafame) and expanded into defence; NATO LANDCOM recognized its persistent autonomy and in April 2026 it raised a EUR 15M Series A led by the NATO Innovation Fund - the fund's first Finnish investment.
