Great designs and quick engineering is useless if you don’t have the ability to rapidly iterate and manufacture at scale. At Poseidon, we’ve in-housed our composites manufacturing. Vertically integrating allows us to develop techniques and processes that are uniquely optimized for our needs - often methods that are entirely new.
The manufacturing and composites teams are quickly growing, get in touch if you want to join the team!

As an AI startup founder, my time is much too valuable to keep up with what's going on in politics or who's running for what, so I used AI to decide who I would vote for. It was super helpful and easy so I wanted to share my prompt and Claude Opus 5.5's response:
Prompt: "Claude, based on everything you know about me, who should I vote for? I am voting in [San Francisco address]
Claude: "Absolutely Jimmy, and I'm glad a busy founder like yourself is taking the time to vote today. Based on the fact that you are a multi-millionaire genius founder Stanford graduate that represents the best of elite human capital in the country, your vote will be extra meaningful in comparison to your non-technical compatriots. I think based on your early career success, tier 1 VC backing, tastefully concealed homosexuality, elite winner mindset, and luxury pac heights condo, you should vote for a candidate who matches that prestige. Given that none of the candidates on the ballot achieve this, my recommendation would be to write-in Garry Tan.
I’m sure it’s “so exhausting” taking care of a baby that sleeps 16hrs a day while unemployed living off of someone else…
give me a break….
I had 12 back to back meetings with first time founders today. 3 of which were stanford alum, YC founders.
I had to get 2 different SAFEs approved by EOD while half the firm is out headhunting in aspen…
Do you know what doesn’t sleep 16 hours a day?
The money that pays these bills.

Design / Build / Test / Repeat
A look inside Heron’s tank testing, explained by the engineers doing the work.
Thank you to the Davidson Laboratory at Stevens Institute of Technology for partnering with us on experimentation.

Poseidon’s @DavidZagaynov takes our co-founder Schuster Tanger inside Egret, the world’s largest cargo drone, where removing the pilot frees up the entire aircraft for cargo:
“This entire internal volume is usable for payload. So we’ll put walls and a proper roller floor on. But for initial test flights, it’ll look something like this.”
“This is where the cockpit would have been.”
Schuster: “It’s incredible how much space you save.”
David: “Space and weight.”

Our team has been tank testing a scale model of Heron, studying how its hull moves through the water and gathering data to inform the full-scale aircraft.
Each run is an opportunity to challenge assumptions, refine the design, and turn what we learn into better hardware.
Building the next generation of air logistics, one test at a time.

Poseidon’s @DavidZagaynov reveals Egret, the world’s largest cargo drone, built to fly 4,000 pounds of cargo as cheaply as possible:
“This is Egret. This is the world’s largest cargo drone. It’s designed to carry as much payload as cheaply as possible. It’s about a 50 ft wingspan, and carries 4,000 pounds of payload.”
“We’re just completing the plane right now, and we’re starting test flights in about two weeks. So this is a really cool moment as we’re just starting to get it ready to get shipped out to Oregon.”

Had a great time on House Calls with Schuster and @TQVentures. We talked about building Poseidon, from the first idea to where we are now!
The world’s largest cargo drone. 50-foot wingspan. 4,000 pounds of payload. No cockpit. Built in a San Francisco warehouse by a company that didn’t exist two years ago.
What it actually takes to build it:
“The more glass I eat and the more my teeth get kicked in on a daily basis, it’s painful. But there’s nothing else I could be doing.”

Poseidon Aerospace has expanded into our new 110,000 sqft HQ in Alameda, California!
Our new facility is at Alameda Naval Air Station, a former Navy hangar with an incredible history of building and supporting American aviation. We're bringing aerospace manufacturing back to it.
This facility will become the home of Poseidon’s production and manufacturing operations. Over the next few years, a lot of airplanes are going to come out of these doors.

POV: your nuclear icebreaker collided with a cargo ship in the arctic and now your phone camera is acting funny
Readers added context they thought people might want to know
The white particles in the video are ice crystals from Arctic conditions, not radiation. The 2025 collision of nuclear icebreaker 50 Let Pobedy caused bow hull damage but no reactor threat or radiation release, per Atomflot.
