Hello, Noemi

From sea to sky, from Norway to the world. At Elfly Group, we’re building the future of coastal mobility through the Noemi, the world’s first fully electric seaplane. Our versatile, 9 passenger electric seaplanes can also move up to one tonne of cargo - quietly and with no emissions. City harbor to city harbor? Easy. We’re amphibious too - requiring only short distances for takeoff and landing at traditional airports.

Elfly is a growing startup company with a multinational team of twentyfive employees. The work atmosphere is informal and playful. With us you will experience startup life where your voice will matter and days fly by. At least that’s how we feel about it :-)
