Why we exist
We spent nearly a decade in construction equipment rental, watching machines deployed without any safety solution — because the existing tools are too expensive, too complex, or too fragile for the field.
So we built Flash Protec': simple, affordable, deployable in minutes on any machine, that works day or night, everywhere.
How it works
The magnetic beacon on the machine emits a configurable safety bubble. The workers' wristbands listen continuously.
The moment a worker enters the zone, their wristband vibrates, the beacon flashes. Operator and worker are warned at the same time.
The accident is avoided. No tragedy. Your crews go home. That's all that matters.
Flash Protec' in action
On the ground
In the morning, the supervisor opens their case. They hand ten wristbands to the crew, attach two beacons on the machines by simply snapping them on magnetically. It's ready.
During the day, if a worker gets too close to a moving machine, their wristband vibrates and the beacon flashes. Operator and worker are warned at the same time. No tragedy, no paperwork — just a risk avoided.

What they say about it
Usually you tune out the alarm. You trust the operator. With this, you look up when it vibrates.

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