Meteomatics: AI-Powered Weather Forecasting API with 1km Precision for Enterprise Customers

Meteomatics AG, a St. Gallen, Switzerland-based weather technology company founded in 2012 by CEO Martin Fengler (PhD, mathematics focused on numerical weather prediction), provides an enterprise-grade Weather API that delivers AI-powered weather forecasting with 1-kilometer precision to customers including Tesla, CVS Health, and Swiss Re. The company's API aggregates data from more than 110 weather sources, including its own autonomous weather drones, and updates forecasts every hour with precise predictions for areas as small as one square kilometer—far exceeding the resolution available from conventional weather services. Meteomatics' unified data platform translates heterogeneous weather data formats from multiple industries into a single consistent structure, making weather data accessible via API to enterprise customers running their own AI algorithms. The company launched the US1k, an ultra-high-resolution numerical weather prediction model, to deliver game-changing precision across the United States. Meteomatics raised a $22 million Series C round in January 2025 to fund U.S. expansion and accelerate development of its global one-kilometer weather model—the company's stated 'North Star.'
