Three solutions, one jobsite

Where your people are. Where your machines, loads and flows go.

Why we exist

Eight years in the construction industry. Too many preventable accidents.

We spent close to a decade in construction equipment rental, watching machines deployed without prevention tools — because the existing ones are too expensive, too complex, or too fragile for the field.

So we built Sharing Worker: simple, affordable, deployable in minutes on any jobsite, working day and night, anywhere.

5 min to equip a full jobsite
€0.50 per day to protect one worker
100% autonomous — no network required

How it works

Detect. Alert. Save.

Step 1

Detect

The magnetic beacon on the machine (or on a crane's hook block) emits a configurable safety bubble. The workers' wristbands listen continuously.

Step 2

Alert

As soon as a worker enters the zone, their wristband vibrates, the beacon flashes. Driver and worker are alerted at the same time.

Step 3

Save

The accident is avoided. No tragedy. Your crews go home. That's all that matters.

In the field

From the highway at night to the crane hook block.

What they say

Those who wear it. Those who run it.

Usually, you forget about the back-up alarm. You trust the driver. Now, you look up when it vibrates.

If the flash lights up, I know the wristbands are vibrating. It's good that we're looking for solutions — I'm scared when they have their back turned to me.

Frequently asked questions

What everyone asks us.

Are you really replacing cameras and Lidar?
For machine-to-worker and load-to-worker prevention, yes. Cameras and Lidar cost €4,000 to €11,000 per machine — so nobody equips their entire fleet. With us, it's €49/month per machine. You equip everything, everywhere, day and night, without relying on light or visibility. What a camera cannot do: alert the worker on the wrist, no eyes needed, no sound needed.
Does it really work without Wi-Fi or 4G?
Yes. That's our offline-first architecture: beacons and wristbands talk peer-to-peer over UWB, no server, no connection. An internet connection is only required for the initial setup. That's what won us jobs on nuclear sites, in tunnels, on defense sites — anywhere video is forbidden or inoperative.
What's the total cost to equip a jobsite?
Less than €300 per month for a jobsite with 2 machines protecting 10 workers. The equivalent of half a day's rental for an excavator. À-la-carte pricing: €129 fixed fee per site, €49 per beacon, €9.90 per wristband (~€0.50 per day per worker). For Vigigrue (1 crane + 10 workers), our package is €277/month. No long-term commitment.
How long does it take to deploy on a new jobsite?
Five minutes. You magnetically attach the beacons to your machines (or to the crane hook block for Vigigrue), you hand out the wristbands to your workers, you set the range from the mobile app — that's it. No wiring, no drilling, no machine modification, no training. That's what lets our customers redeploy the solution from one jobsite to another, with no installer.
