WindBorne Systems aims to deliver better weather forecasts built on a proprietary balloon-based atmospheric sensing platform. Their system can travel a quarter of the way around the world in a single flight and navigate to capture data with the highest impact, filling the huge gaps in traditional measurements. The company is backed by Khosla Ventures, and the team, led by a Thiel fellow and a Hertz fellow, was recognized by Forbes 30 under 30. They developed their world-record-breaking technology through four years of Stanford research, and are working to build the next generation of weather prediction with the mission of helping humanity adapt to the growing threat of climate change -- and the extreme weather that comes along with it.
