As the planet warms, we're experiencing more frequent and destructive extreme weather. Yet, 85% of the world lacks critical atmospheric data for precise forecasting that could help us better prepare. John Dean and Kai Marshland, Co-Founders of WindBorne Systems, are on a mission to close this gap. Born out of the Stanford Student Space Initiative, WindBorne began as a project to extend the flight duration of conventional weather balloons. Realizing the impact of their technology on climate change, they turned their project into a venture-backed startup serving both private and government partners like NOAA and the U.S. Air Force. John and Kai share how WindBorne deploys a global constellation of autonomous, navigable, AI-powered balloons that fly longer, are more sustainable, and collect more real-time measurements than standard balloons. Their data is fed into powerful AI models to create the world's most accurate forecasts – better than Google DeepMind’s GraphCast – unlocking the potential to improve disaster preparedness and climate resilience worldwide.
