Signalcraft

The problem

Factories repair machines after they break, and an hour of unplanned downtime on a production line costs more than a month of maintenance.

The solution

Signalcraft listens to the vibration of each motor with a clip-on sensor and warns the maintenance team a week before a bearing fails.

Who it's for

Mid-sized manufacturers with 50–500 rotating machines.

Market

Bottom-up: about 90,000 customers like this in Czech Republic and nearby, worth roughly $160 million a year at our prices.

Competition and edge
