We build systems
that check
their own work.

We build AI agent systems and hardware, and everything we build comes with the test that proves it works.

Not a demo and an adjective. A deterministic gate, agreed in writing before the build, that returns pass or fail with a measured value — and keeps running after we hand it over.

verdictFAIL2 of 6 gates

One of our own reviews: an early HC-01 enclosure, failed on four measured rows before it was fixed. Every engagement includes one of these.

We built three of these for our own work first.

Each has run end to end on our own work. Each has a review engine that can fail it. The last one has never approved a product, which is the point.

Hardware design pipeline

7 agents

Takes a parts list and functional intent, returns a fab-ready 2-layer PCB, a printable enclosure fitted to it, and ESP-IDF firmware wired to the board's own pinout.

Every purchased electronic part must be modeled from real geometry: a vendor STEP or a model built from measurements. A placeholder box fails the review unless it carries a written waiver.

Video delivery pipeline

3 agents

One 360° master in; a widescreen cut, a vertical cut, the 360 file, stills, a 360 player and setup instructions out, unattended: it claims a job from a queue, plans the camera moves, renders, checks its own output, then publishes a hosted tour.

The check measures whether the vertical cut was framed independently — a center-crop of the widescreen fails, even though it looks fine.

Product research pipeline

5 agents

Researches a market, prices a product against its real page-one competition, and recomputes the margin from cost inputs rather than trusting the claim.

Nine deterministic gates. Across seven cycles, 48 candidates: none reached GO, 46 were killed with the measured reason, 2 are parked.
