KNOW WHEN AND WHERE A FLASH FLOOD WILL HIT.

Local warning for the creek, bridge or neighbourhood your team has to protect. Our sensors measure water level in small streams every five minutes and send threshold alerts from the day they go in. Through the pilot we add weather-radar data and build a forecast for your catchment.

Developed with 50 fire-brigade chiefs. First Swiss deployment September 2026.

A REGIONAL RISK LEVEL CANNOT TELL YOU WHAT HAPPENS AT ONE BRIDGE.

Weather radar shows where rain is falling. National bulletins cover wide areas and major rivers. A fire brigade needs to know whether one specific creek will rise, when the water reaches a critical point, and which procedure to trigger.

The warning has to be local enough to act on and reliable enough to trust.

of floods are flash floods. They form at small spatial scales and can develop in under six hours.

CASE STUDY

In July 2025, flash floods swept the Texas Hill Country. The Guadalupe River rose in the early hours of the morning. More than 100 people died, among them children at a riverside summer camp. The same region flooded again in July 2026.

FROM RAIN OVER THE CATCHMENT TO A DECISION ON THE GROUND.

Measure the critical points

Our sensors sit in creeks, small streams and dry channels where flash floods begin. They measure water level every five minutes, including at remote sites with no mobile network.

Learn the local response

During the pilot we combine the in-stream readings with weather-radar data. The model learns how rain over the catchment changes water levels at the places your team has to protect.

Alert the response team

Threshold alerts run from the day the sensor goes in. The forecast layer adds an estimated arrival time, a named location and a confidence level as the model trains on your catchment.

WARNING TIED TO A PLACE AND A PROCEDURE.

Watch known risk points

Monitor the streams, bridges, underpasses, campsites and dry channels where your team already knows water becomes dangerous.

Send teams to the right location

Each alert names a stream and a critical point, so the response team knows where conditions are changing.

Act before the water arrives

Use the lead time to close a road, position crews, warn properties or evacuate a campsite.

Set clear response thresholds

Connect measured water levels to an greed procedure. Your team gets a number and a location it can act on.

BUILT WITH THE PEOPLE WHO RESPOND.

We have spoken with 50 fire-brigade chiefs about how a local flood warning has to fit a real operational decision. Our co-founder Martijn Bosch built and sold a startup, which made infrared smart glasses that let firefighters see through smoke. Our first Swiss fire-brigade deployment starts in September 2026.
