Funding Round and Company Background
Tomorrow.io announced an additional $35 million investment, bringing its Series F financing to $210 million. Existing backer Pitango and Harel Insurance contributed alongside private-equity firms Stonecourt Capital and HarbourVest Partners, which led the round in February after a $175 million tranche earlier in the year. The capital will accelerate DeepSky, a next-generation constellation that will replace the six-unit CubeSats of the Gen1 network—11 microwave sounder satellites that now provide global atmospheric data every 60 minutes. Founded in 2016 as ClimaCell by Israeli entrepreneurs Shimon Elkabetz, Rei Goffer and Itai Zlotnik, the Boston-based firm rebranded to Tomorrow.io; Elkabetz serves as CEO and co-founder, Goffer as co-founder and chief strategy officer.
Timeline and Funding Milestones
Key milestones: 2016 – company founded as ClimaCell; early 2024 – Series F round launched; February 2024 – $175 million tranche disclosed after Gen1 achieved a 60-minute global revisit rate; May 18 2024 – $35 million added, completing the $210 million Series F round.
Quantitative Overview
Tomorrow.io’s Gen1 constellation comprises 11 microwave sounder satellites delivering atmospheric observations every hour worldwide. DeepSky satellites will be significantly larger than the six-unit CubeSats used in Gen1, though exact specifications were not disclosed. The cumulative investment in the company’s space-based weather platform now exceeds $385 million.
Strategic Significance
Tomorrow.io positions DeepSky as a source of proprietary, high-resolution atmospheric data for AI models, arguing that weather, a major economic driver, remains under-integrated into operational decisions across aviation, energy, logistics and government. By feeding real-time observations into an “agentic” AI platform, the firm aims to provide actionable intelligence that mitigates weather-driven disruptions.
Official Company Statements
Company officials said the new capital will speed DeepSky’s rollout, expand the satellite observation network, and fund the agentic AI platform that translates raw weather data into real-time operational guidance. Executives stressed that the financing strengthens Tomorrow.io’s role as an infrastructure layer for organizations that rely on precise, timely weather intelligence.
