Tomorrow.io, a Boston-based weather intelligence company, has secured an additional $35 million in funding, bringing its Series F round to $210 million. The new capital came from existing investors Pitango and Harel Insurance, joining private equity firms Stonecourt Capital and HarbourVest Partners, who led the round earlier this year. The funding will accelerate the development of Tomorrow.io’s next-generation DeepSky satellite constellation, designed to gather advanced atmospheric data.
The company’s first-generation network of 11 microwave sounder satellites achieved a global 60-minute revisit rate for atmospheric observations. DeepSky satellites will be significantly larger and equipped with multiple co-located sensors, representing a major leap in capability compared to the smaller Gen1 cubesats. Cofounder Rei Goffer described them as a “completely different caliber,” aimed at delivering higher-quality, proprietary data.
The additional funding will also support Tomorrow.io’s artificial intelligence initiatives, including the development of an “agentic” platform that transforms weather data into real-time operational guidance. By integrating atmospheric data into AI models, the company seeks to help industries such as aviation, energy, logistics, and government better manage weather-driven disruptions.
CEO Shimon Elkabetz emphasized that weather remains one of the least integrated factors in global decision-making, despite its profound economic impact. Tomorrow.io’s mission is to change that by turning observational data into actionable intelligence, with AI integration becoming a foundational capability for operations worldwide.
