Company

We close the gap between CAD and CAM.

DION AI is built by people who spent years on the shop floor. We turn hard-won machining expertise into an on-device intelligence any manufacturer can run on the hardware they already own.

About

Manufacturing knowledge has always lived in a few experienced heads and a dozen disconnected tools. When a veteran leaves, the knowledge leaves with them. DION AI captures that expertise in a deterministic ontology and brings it onto the shop floor — private, precise and vendor-agnostic. We started from fifteen years of mold-design and CNC machining practice, not from a lab.

Vision

A world where any manufacturer can turn design intent into precise machining the instant they need it — securely, on the systems they already run.

Mission

Unify fragmented CAD/CAM into one on-device intelligence, so expertise compounds inside the factory instead of walking out the door.

Principles

On-device

Your drawings never leave the floor. Privacy is the architecture, not a setting you can forget to switch on.

Deterministic

Reasoning stays inside the ontology's bounds. Every number is grounded, never hallucinated.

Field-born

Every decision is grounded in shop-floor practice, not theory.

Team

Built on the floor.

Partnerships

We extend the CAD/CAM platforms our customers already run.

DION AI is not another CAM seat. It ships inside the vendor applications a shop already owns — which makes the vendor relationship part of the product.

Hexagon Manufacturing Intelligence

ESPRIT EDGE · CAMMOU signed

Our deepest and only shipped CAM integration: a native DION AI tab in the ESPRIT EDGE ribbon, installed alongside ESPRIT EDGE in Hexagon's own program directory. An MOU covering joint go-to-market in the Korean precision-machining belt is in place.

Siemens Digital Industries Software

NX · CAD/CAMApproved — S&T technology partner

An NX Open add-in drives NX CAM operations, toolpaths and NC post directly inside the customer's own installation — extending NX rather than competing with it. U2DIA is an approved Siemens S&T technology partner; the NX CAM integration is being delivered under that programme.

NVIDIA

Inception · Innovation LabProgram completed

Sixty days on an 8×H100 SXM5 cluster produced the retrieval-augmented fine-tuning result behind our zero-hallucination contract — published as technical report TR-2026-01.
