Physical AI for industrial SMEs

Automate the dull, dirty & dangerous — with the arm you already have.

LeJunior is a software companion that lets any robotic arm learn a task by watching your operator do it — a few demonstrations, no code, no integrator. One licence. Any arm. Any bench.

The tasks nobody wants — and no one can automate affordably.

“3D” work — Dirty, Dangerous, Dull — fills industrial workshops: sorting, packing, screwing, assembling. It burns people out and can't be justified on a €30k+ cobot for short, changing runs.

Endlessly repetitive

The same gesture, hundreds of times a day. Cognitively draining, demotivating, and impossible to keep staffed.

Physically costly

Repetitive strain injuries are the #1 cause of recognised occupational illness in France — and a €4.9 bn yearly bill.

Impossible to staff

60 000 industrial jobs sit vacant. Owners refuse orders they physically can't find the hands to fulfil.

That's why we built LeJunior

Your operator becomes the programmer.

LeJunior learns a task by imitation — a few dozen demonstrations from the person who already knows the gesture. No code, no robotics background, no integrator on site.

✓ Trained by the operatorShow the gesture; LeJunior reproduces it in any condition, environment or object variation.
✓ Connects to any armSoftware-first. Run it on a $300 open-hardware setup or an arm you already own.
✓ Multi-task by designAdd a new task from the app in under half a day — no reprogramming, no external help.
✓ Runs locallyInference on the edge — no cloud dependency, your production data stays on your bench.

FIG.01 — IMITATION LOOP

From bench to autonomy in a week

Three steps. No integrator.

Observe

We visit your workshop, watch the station and confirm the gesture — grasp, sort, place — is a fit for LeJunior. Two hours, on site.

Demonstrate

Your operator performs the task a few dozen times in front of the arm. A model trains locally — in hours, not weeks. No programming.

Deploy

Launch the task from the app in two clicks. The arm runs autonomously; your operator moves to higher-value work like quality control.

What we sell

One licence. Any arm. All your tasks.

We sell software, not iron. Bring your own arm — even a $300 open-hardware setup — and pay a single annual licence per arm.

And the potential is huge

A growing market, wide open below the giants.

Automation today is binary: full lines above €100k, or manual labour. LeJunior owns the space in between — flexible, affordable, no-code — where the incumbents can't profitably go.

A builder and a closer — who lived the problem.

Both from two of France's most selective schools in their field. This isn't an academic observation; it's a workshop frustration turned into a company.
