WindBorne Systems
WindBorne Systems is building a planetary nervous system for Earth's atmosphere. The Redwood City company operates a constellation of autonomous long-duration balloons that gather high-resolution atmospheric data from remote and ocean regions previously invisible to weather models - then feeds that data into WeatherMesh, its in-house AI forecasting model that has surpassed Google DeepMind's GraphCast as the world's most accurate medium-range global weather forecast. With backing from Khosla Ventures, the Gates Foundation, and U.S. military contracts, WindBorne is making a credible run at replacing century-old weather infrastructure.
John Dean
John Dean is the Cofounder and CEO of WindBorne Systems, a Redwood City, California-based company operating the world's largest constellation of autonomous long-duration weather balloons. A Stanford electrical engineering graduate and former intern at SpaceX, NASA, and Lyft, Dean co-founded WindBorne in 2019 out of Stanford's Student Space Initiative after breaking four world records as undergraduates. The company raised a $15 million Series A led by Khosla Ventures in 2024, and its WeatherMesh AI model surpassed Google DeepMind's GraphCast as the most accurate global weather forecasting model, running on a fraction of the compute power. WindBorne's balloons have flown into Hurricane Milton and have set a new benchmark for how atmospheric data is collected at scale.
