Rainbow Weather, a Warsaw-based climate-tech and AI weather intelligence startup, has raised $5.5 million in a seed funding round to extend its hyperlocal, minute-by-minute weather forecasting technology and broaden commercial offerings to B2B clients. The company’s platform focuses on real-time short-term forecasts delivering precipitation predictions updated every few minutes on a one-square-kilometer grid, helping users and businesses make decisions based on highly precise weather data rather than traditional long-range models. The seed round was backed by a syndicate of strategic investors led by Yuri Gurski, the founder of Flo Health and a veteran of Europe’s consumer tech scene, alongside other contributors from the tech and climate-tech investment community. The fresh funding will be used to extend the forecasting window from four hours to 24 hours, add additional weather parameters beyond precipitation, enhance enterprise APIs, and scale operations across industries such as logistics, agriculture, aviation, and drone services where near-term weather accuracy is critical. Rainbow Weather says its app has already surpassed one million installs globally and has begun supplying real-time data services to commercial partners.
