Creating weather certainty. We fuse unparalleled data from our constellation of smart, long-duration sensing balloons with state-of-the-art AI forecasts.
We are honored to share that WindBorne Atlas was named one of TIME's Best Inventions of 2025. This recognition represents more than an award since it validates our mission to transform weather forecasting through innovative data collection technology.

Here's to building a planetary nervous system!

Q: "How far in advance can you spot a record-setting East-Coast heat wave, and how steady is your signal run-to-run?”

A:
* WeatherMesh-4 showed a consistent signal for above normal temps 15 days out
* IFS mean begins a consistent sig ~13 days
* AIFS and GEFS mean begins a consistent sig ~11 days
