The Key 4 AIDoor one · For you
We engineer it. You hold the result.
You bring a problem. We decide, build, prove and run, and what comes out is yours: on your hardware, in your building, under your control.
Who walks through
Decisions that cannot leave the building, cannot be wrong quietly, or cannot wait for a cloud.
A decision a regulator will ask you to defend.
Someone will ask how the model reached its answer, and whether anyone independent checked it. You need a model you can inventory, validate and explain, and evidence an auditor accepts.
A plant, a grid or a fleet where the consequences are physical.
The network is unreliable, the historian is on site, and a false alarm costs a shift. The model has to run at the edge, name its own failure modes, and be retuned when the process changes.
A record where the data is somebody's private life.
The data cannot travel to a foreign API and cannot be seen by a vendor. The model comes to the data, not the other way round.
A public service that has to work for everyone.
Reach matters more than cleverness: the person at the end of the queue has to be able to rely on the answer. Small, owned models are how that reach is affordable.
What comes out
What you receive.
- 01
A model built for your problem.
Deep learning or a small language model, built for the job, deployed where you are, and yours.
- 02
Assurance of a model you already have.
Independent validation, evaluation harnesses, guardrails and red-teaming, by a party with no interest in flattering it.
- 03
A system that survives production, agents included.
Agents, orchestration and the machinery underneath, deployed on your hardware and then operated rather than handed over and forgotten, with every agent action graded.
One role per model. We build it or we assure it, never both, and you choose which before work starts.
The first step
Small enough to verify us, before you trust us.
A fixed scope, a fixed price, a defined deliverable, and a date. Enough to see the craft on your own problem.

Named before you ask
What the model gets wrong, and what happens then.
Every engagement begins with the failure modes written down: what the model cannot do, what it will get wrong, and what the system does when it does. A vendor who names the failure mode first is the one to trust with the rest.
Light enough to live on what people already own.
