Record-breaking AI forecasts

Atmospheric data is the biggest missing piece to improving modern forecasts. We fuse data from our long-duration balloons with state-of-the-art AI models to produce the most accurate weather forecasts.

Novel, global atmospheric data at a fraction of the cost

Up to 250x more data per dollar

Rapid global access via international launch sites

Targets crucial real-time data, not otherwise captured

Complete access, from surface to stratosphere

WindBorne designs, builds, and operates the only technology that can capture in-situ atmospheric profiles everywhere, including over oceans and the Earth’s most remote places. Each balloon can maintain or transition between any altitude from sea level to 20 km, autonomously flying for weeks at a time.
