ClimateAi is a San Francisco-based climate-tech company that builds an AI-powered climate resilience platform. Founded at Stanford in 2017 by Himanshu Gupta and Max Evans, its ClimateLens platform combines patented machine-learning models with physics-based climate and weather data to forecast risk from weeks to decades ahead. Food, agriculture, and water-dependent companies - including Dole, Suntory, Oatly and McCain - use it to protect sourcing, planting, and procurement decisions against a more volatile climate.

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.
