Why Flash? The world’s first AI that predicts lightning and hail before it hits.
Every other weather tool tells you what already happened. Flash tells you what is about to. Where and when lightning and hail will strike, down to the kilometer and the minute, up to an hour before they do. Up to 99.6% accurate.
The category nobody else is in
There are three kinds of weather tools. Only one tells you what happens next.
Detection
Tells you lightning is here, right now. Radar shows rain already falling. Sensors log strikes that already hit the ground. Useful, but by the time it alerts you, the bolt has already landed. You are reacting.
Forecasting
Tells you storms are possible, somewhere in your county, sometime today. It is the app on your phone and the legacy providers behind it. Too broad and too slow. A summer storm can form, hit, and pass inside a single update cycle.
Prediction. This is Flash.
Tells you exactly where and when lightning and hail will strike, before they do. This field. This hour. Not a faster radar and not a denser sensor network, a forecast of the storm that does not exist yet. Nobody else can honestly use that word.
Detection describes the present. Forecasting describes the maybe. Prediction is the only one that gives you time.

For your operation
An hour of warning changes how you run everything.
An hour of lead time is the difference between managing a situation and reacting to one. A golf operation pages the course, stages the carts, and protects the tee sheet instead of refunding it. And when the threat passes, Flash All Clear tells you the moment it is actually safe to go back out, not thirty arbitrary minutes later.
- less weather-related downtime
- 30-50%
- lower weather-related losses
- Up to 70%
