Rainbow Weather Raises $5.5M For Hyperlocal Forecasting
7.1
Warsaw-based Rainbow Weather raised $5.5 million in seed funding on 26 January 2026 to advance hyperlocal, minute-by-minute weather forecasting. Its mobile app currently delivers four-hour precipitation forecasts refreshed every 10 minutes on a one-square-kilometre grid; the company plans to extend to 24-hour forecasts, add more weather parameters, and expand B2B APIs. The round included investor Yuri Gurski among a syndicate of backers.
