# WindBorne Systems Raises $37M Series B for AI-Powered Weather Intelligence

> WindBorne Systems raised a $37M Series B, co-led by Khosla Ventures and Galvanize Climate Solutions at a $250M valuation, to prove that better weather forecasting can also be a business. Its edge starts in the sky: roughly 600 long-endurance balloons across 20 launch sites gather atmospheric readings from places that are hard and expensive to measure. That data feeds proprietary deep learning models, and the payoff is efficiency as much as accuracy. WindBorne says its AI can produce forecasts on a standard laptop where the old numerical methods demanded supercomputers, and that adding its balloon measurements yields more value per data point than leaning on satellites alone. Most revenue today comes from US government customers like the National Weather Service, the Air Force and the Navy, with commercial interest growing among commodity traders who live and die by the forecast. It is a clean example of applied AI, where a novel data source plus a good model turns weather into a product.
