WindBorne Systems

WindBorne Systems designs, builds, and operates a constellation of long-duration smart weather balloons. The company is based in Redwood Shores, California. The site says its technology is invented, designed, and manufactured in the USA. It describes its goal as collecting the most critical atmospheric data.

The company runs a fleet of balloons called Atlas. The company says Atlas is the largest balloon constellation in the world. It says the fleet launches hundreds of autonomous balloons each month from global launch sites. The stated goal is to close atmospheric data gaps from pole to pole.

The company's Global Sounding Balloon can control its altitude. The site says it flies for weeks at a time. It says each balloon can collect around 50 controlled vertical profiles. A traditional weather balloon collects one profile and lasts around two hours. The company says its balloons can reach oceans and remote places.

WindBorne also offers AI-based forecasts. Its deep learning forecast model is called WeatherMesh. The company says the model uses its own proprietary data. The website lists three product areas: observation data, AI forecasts, and weather solutions. It names energy trading and utilities as industries it serves.

The site says the company has partnerships with U.S. and international governments, private companies, and philanthropic groups. It links to pages about federal contracts and a partnership with the Gates Foundation. The site also mentions NOAA.

The website has pages for API docs, benchmarks, an FAQ, and live access to its data. It has a contact form for business inquiries. Media inquiries go to a separate address.
