Poseidon
HQ AlamedaFounded 2024
Poseidon Aero is building autonomous sea gliders that fly just above the water’s surface to transform regional cargo logistics. By harnessing the aerodynamic ground effect, these wing-in-ground vehicles offer the speed of air freight with the affordability of ocean shipping, all while bypassing traditional infrastructure like airports. Their first two vehicles—Seagull and Heron—are designed for high-priority deliveries and bulk cargo, respectively, and can take off and land on water without human crews onboard. Poseidon is poised to redefine how goods move across island nations and coastal regions, offering a greener, faster, and cheaper alternative to current methods.

“# Heron unmanned seaplane P50-H-01 # Heron unmanned seaplane To drive operating costs as low as possible, Poseidon reimagined everything that doesn't make moving your cargo more efficient. The result is Heron: an autonomous seaplane with no seats, no landing gear, and no wasted weight. Every ounce of Heron is optimized for one job: to transport your cargo as efficiently as possible. Designed as a seaplane from the ground up, Heron can launch and land where others can’t: on almost any body of water on Earth.”
