Poseidon Aero
Uncrewed fixed-wing cargo aircraft for defense and regional logistics
About Poseidon Aero
Poseidon Aero (Poseidon Aerospace) is an Alameda, California company building uncrewed fixed-wing cargo aircraft for defense and regional commercial air cargo. Co-founded by CEO David Zagaynov (formerly Amazon logistics) and Parker Tenney (formerly Lockheed Martin), Poseidon designs combustion-powered planes such as Egret and seaplane variant Heron that drop the cockpit and life-support mass of crewed freighters so payload-to-empty-weight improves and operating costs fall versus pilot-dependent hub-and-spoke cargo. The company is not pursuing eVTOL or hydrogen/electric powertrains; it targets remote and underserved routes with degraded infrastructure and plans to operate its own regional cargo service rather than sell aircraft. After a quarter-scale Seagull demonstrator and an about $11 million seed, Poseidon closed an oversubscribed $60 million Series A in September 2026 led by TQ Ventures, with Hanwha Asset Management, G Squared, JAWS and existing backers Starship Ventures, Draper Associates and Drover Ventures, ahead of a planned first full-scale Egret test flight by end of 2026 from an Alameda Navy hangar.
