Flight software that earns the airframe its trust.
We write and harden the code between the flight controller and the mission — PX4, ArduPilot, and custom flight stacks — for operators who need to know exactly who wrote it, where, and why.
Three layers. One team that owns all of them.
PX4 & ArduPilot customization
Custom flight modes, mixers, sensor drivers, failsafe logic, parameter tuning and board bring-up on the two most widely flown open flight stacks.
Firmware services →Autonomy & mission software
Companion-computer software that turns a stable airframe into a useful one: MAVLink integration, path planning, perception hand-off, and multi-aircraft coordination.
Flight software →Gazebo simulation & test
Every behavior is proven in simulation before it touches a propeller. We build the models, the worlds, the scenarios and the regression harness.
Simulation →You should be able to name every person who touched your flight code.
With Visie you can. Every line is written by US-based developers, on hardware we control, in repositories you own from day one.
How we work- US citizens, US soil, US-hosted repositories — no offshoring, no subcontract chains.
- Local-first toolchain: builds, simulation and CI run on machines we administer, not a shared cloud tenant.
- Platform- and sensor-agnostic. We don't sell airframes, so our advice isn't bent toward one.
- Firmware we don't yet own, we're prepared to write. Custom stacks are in scope when PX4 or ArduPilot isn't the right answer.
From first call to first flight
Scope
A 45-minute call. We learn the airframe, the mission and the constraint that's actually blocking you.
Architecture
A written technical plan with at least two candidate approaches and the reason we recommend one.
Simulate
Behavior proven in Gazebo and SITL with a regression suite you keep.
Fly
HIL, then tethered, then free flight — on your aircraft or a surrogate we agree on.
Hand-off
Source, build system, docs and a recorded walkthrough. No lock-in by design.
