Poseidon Aerospace builds autonomous fixed-wing cargo aircraft aimed at both defense logistics and regional commercial freight. Its first plane, Egret, is a 4,000 lb payload aircraft with a 50 foot wingspan and a 1,600 mile range , with a seaplane variant called Heron in development. Rather than pursuing vertical takeoff, hydrogen, or electric powertrains, Egret and Heron are fixed-wing aircraft powered by conventional combustion engines , a deliberately conservative airframe strategy that the team argues is the fastest path to lower per-ton costs.
The San Francisco company was founded in 2024 by David Zagaynov, Parker Tenney, and Isaac Baumstark . Zagaynov, the CEO, studied computer science at UC Berkeley and worked as a software engineer at Amazon, while CTO Parker Tenney studied mechanical engineering at Cal Poly and worked at Lockheed Martin . This launch marks a $60 million Series A led by TQ Ventures, with new investments from Hanwha Asset Management, G Squared and JAWS, and follow-on checks from Starship Ventures, Draper Associates and Drover Ventures , following an $11 million seed round last year. The raise comes ahead of the first test flight of Egret, expected by the end of this year .
The strategic bet is worth noting for operators and investors watching aerospace: Poseidon does not plan to sell its planes, instead it intends to operate its own regional air cargo business and compete with incumbent carriers for work from UPS, FedEx, and others . Initial targets are the defense and regional commercial cargo markets , with the defense pitch focused on serving remote routes and degraded-infrastructure environments where crewed logistics networks are hardest to sustain.

Tweet buries the actual plane behind a truncated link. Bro you raised 60M, show me the wing before the cap table.

Autonomous cargo planes is a bold sentence to type in 2025. What's the certification path looking like, or is that a Series B problem?

Every dual-use pitch this year sounds like it was written by the same ghostwriter. Where's the actual differentiation from the twelve other autonomous cargo startups?

Tagline rewrite, no charge: 'Freight that flies itself.' You're welcome.

The investor list reads like a defense tech bingo card. Hanwha in the mix is the tell that this is more defense than logistics.

Genuinely asking, does 'designed and built from' get finished somewhere or did the tweet just get shot down mid-flight?

Ops question nobody asks: where are these landing? Half the value of cargo aviation is the ground handling and you can't autonomize a forklift driver in Boise.

Announcement thread has one tweet and a broken link. Respect the restraint honestly, everyone else would've made this a 14-part manifesto.

Any demo footage that isn't a rendered flyby? I'll wait.

Recruiter hat on: if you're hiring avionics or GNC engineers I have a stack of resumes from a certain LA hardware company that just did layoffs.

Every 'unmanned backbone' pitch eventually meets the FAA and discovers backbones can be broken.
