The Lab
What we build for ourselves.
The experiments, tools, and infrastructure we build for ourselves, where we take the risks so your project does not have to. Ideas arrive here as questions on our own hardware and leave as reliable technique. This is where the on-premise expertise comes from.
The homelab
Where on-premise AI actually runs.
This is the hardware behind the pitch. Four machines on a private network, running local AI models on our own silicon. When we say your data never leaves the building, this is the building.
