We built the world's largest cargo drone @poseidonaero

You can’t bomb the ocean out of existence so a seaplane will always have a place to land

Thanks @SnoozyWeiss and @TheFP for coming by @poseidonaero offices!

@mattfreed @zipline Why not make your own parts?

the Poseidon team is growing

Alright listen San Francisco. Everyone cant sell shovels. Someone has to mine something.

@BikeTaxiGuy @peteoxenham @bennbuilds Assuming that an engineer thinks through every part of their design is extremely naive. Design intent is talked about plenty but rarely acted upon since it requires full stack engineering experience which few people have.

"aerospace engineering is a serious discipline"

sure and the soviets made a plane with backward wings, im not buying it

gravity has taste, if it looks sick it will fly

We've raised our $11M seed to build autonomous cargo planes at Poseidon Aerospace.

We are building the future of air freight with unmanned platforms, designed from the ground up to move cargo significantly cheaper and faster.

Led by Tamarack Global with participation from Drover Ventures, Draper Associates, Starship Ventures, Cade Ventures, GoAhead, Fortitude Ventures and angels.

In today’s operational environments, logistics are no longer guaranteed.

In day one of a conflict, access to ports and airfields can be contested or denied altogether, leaving critical supplies stranded far from where they’re needed most. Traditional platforms incur significant tradeoffs: fixed-wing planes are limited by runway access, helicopters are exquisite expensive solutions, and vessels are bound to deepwater ports and lack the speed for a fast response when timelines collapse. The result is a logistics chain that becomes brittle at precisely the moment it needs to be most resilient.

We are building Heron to break that bottleneck. Operating amphibiously with no reliance on runways or ports, it delivers ton-class cargo directly across the littorals at a fraction of the cost and time of existing options.

Heron’s combination of sea access and ground-effect flight creates an independent logistics axis that survives the loss of fixed infrastructure, preserves operational tempo, and ensures combat power is sustained in denied environments. In contested logistics, speed, adaptability, and infrastructure independence are the difference between mission success and failure.

hiring a avionics engineer to join the poseidon team!

we’re gonna fly things that have never been flown before

I would love to see AI in CAD, but I have almost no interest in AI based CAD.

What I want: "NX - replace the M5 fasteners in this design with M6, update all hole features, and replace the part files and references using McMaster."

"NX - Create a tool assembly for the 6mm end mill open in my web browser now, with a RegoFix BBT30 PG15 70mm holder, and pull all available Fraisa speed/feed/engage data into that tool, modified to my Speedio 20k spindle profile."

What Everyone Is Trying To Achieve: "AI CAD: Here is an amorphous, big task. Magically do it."
::AI CAD outputs total junk::

Most of CAD/CAM work is busywork. Pulling part numbers from catalogs, importing model files, finding tools, looking up their feeds/speeds, managing data. This is 75%+ of the workload. All I want is smarter tools that minimize all the inputs to that grunt work and have enough awareness to be exceptionally accurate.
