About us

Catch leaks in seconds

Pressure, flow and acoustic monitoring flags leaks and bursts in under 60 seconds — before they surface or reach the bill.

See use cases

Cut energy waste

Sub-metering and anomaly alerts show where energy is lost across buildings and sites. Typical savings: 30%.

See use cases

Prevent unplanned downtime

Condition monitoring on critical machines cuts unplanned downtime by 25% and lifts OEE by 8 points.

See use cases

Use less water

Irrigation driven by soil and weather data uses 20–40% less water than fixed timers — with healthier crops.

Industries we serve

We don't sell sensors. We move the metrics that show up on your P&L — downtime, energy, water, yield, safety — in the language of your industry.

Discuss your project

Smart Manufacturing

-25% unplanned downtime. +8pt OEE.

Most factories aren't ready for IoT — they're ready for a proper asset registry. We get you from L0 to connected, in stages that stick.
