Brightband, a startup founded by a former Google executive, aims to improve weather forecasting using artificial intelligence. The company announced on Thursday that it has secured $10 million in Series A funding, led by Prelude Ventures, with participation from Future Back Ventures, a division of Bain Capital, and Slack co-founder, Carl Henderson. Launched this summer by former Google executive Julian Green and three scientists, the company aims to develop a paid product, as well as an open-source AI forecasting model trained on raw weather observations. In an interview, Amy McGovern, Brightband co-founder and professor of computer science and meteorology at the University of Oklahoma, said that Brightband will initially focus on predicting the behavior of extreme weather, including heatwaves and tropical cyclones, days ahead of traditional forecasts.
