Cloudline

Cloudline builds autonomous solar-powered airships that transform unmanned aviation with breakthrough cost advantages and zero carbon emissions. The company's lighter-than-air vehicles use helium lifting gas and battery-solar propulsion to deliver carbon-free flight operations at a fraction of the cost of traditional rotorcraft or helicopter services. Cloudline airships offer a range of over 400 km, endurance of up to 12 hours, and payloads up to 40 kg (88 lbs), with vertical takeoff and landing capability that eliminates the need for fixed infrastructure. Each airship saves up to four tonnes of carbon emissions per day compared to helicopter operations. Applications span cargo delivery, logistics, infrastructure inspection, and connectivity in remote or underserved regions. The company was co-founded in 2017 by Spencer Horne and is headquartered in Cape Town, South Africa, with a team of 13 dedicated to innovation in autonomous aviation.
