Designed in Portugal. Built for contested airspace.
Post77 is an autonomy-first drone company. We engineer and build Aethon — an open-architecture VTOL ISR and strike platform — at Oeiras Tech Valley, outside Lisbon. Designed for operators who cannot accept vendor lock and cannot tolerate downtime.
FIELD PRINCIPLES
We build for the crew on the ground.
- P01
Open architecture
P77 Aegis is documented down to the autopilot API. No vendor lock. Integrators can extend — we do not hold the ceiling.
- P02
Field-hardened, not lab-clean
We qualify against dust, salt, electronic interference, and contested GPS. Simulation is necessary, not sufficient.
- P03
Autonomy without theatre
Aegis is the AI stack for when the link drops. It finishes the mission with the compute it was given — not the compute in a datacentre.
- P04
Export-aligned by default
We qualify for EU dual-use and align with ITAR requirements from the first review. Allocations are ordered; the paperwork is ready.
FIELD MANIFESTO
A better drone is a sovereign drone.
The last decade of small-UAS procurement was a race to the cheapest foreign-built airframe with the most opaque stack. Operators paid in hours of downtime, forced upgrades, and mission risk they did not author.
Post77 starts from a different axiom: if the platform is going to be in contested airspace, the operator needs to own the platform. Not brand it. Own it. That means open interfaces, documented autopilot, verifiable supply chain — and manufacturing we control, in a country where we can be held accountable.
Aethon is the first expression of that idea. Aegis is the brain. Both are built to be extended, audited, and replaced — not ring-fenced.

Formal decks are shared under NDA. Multi-year allocation requests are prioritised.
