$175M Funding Boosts Tomorrow.io’s Expansion of Weather Satellite Network

Tomorrow.io, the Israeli-founded weather intelligence company, has secured a massive $175 million in new funding to advance its vision of a real-time, space-based weather monitoring network. The latest round led by Stonecourt Capital and HarbourVest pushes the Boston-based firm’s valuation past $1 billion and brings total fundraising to over $500 million.

The investment will accelerate the development of DeepSky, Tomorrow.io’s advanced low Earth orbit satellite system. DeepSky aims to deliver continuous, global coverage of the atmosphere and oceans with unprecedented speed and accuracy, helping to better predict extreme weather events like hurricanes, floods, and heatwaves.

Founded in 2016 by Israeli Air Force veterans Shimon Elkabetz, Rei Goffer, and Itai Zlotnik, the company originally known as ClimaCell emerged from a deep frustration with outdated and sparse weather infrastructure. The founders realized the main bottleneck in forecasting wasn’t computing power, but inconsistent and thin data, particularly in vulnerable regions like Africa, India, and the Philippines.

Tomorrow.io completed its first radar satellite constellation in January after launching 13 satellites into orbit. These small, cost-effective units ranging in size from shoeboxes to mini fridges can refresh data for every point on Earth approximately once an hour. That’s significantly faster than the 3-5 hour cycles typical of government weather systems.

By feeding this high-frequency data into its AI-based forecasting tools, Tomorrow.io is working to close a critical gap in global climate resilience. Already, NASA, the US Air Force, and over 250 clients including Uber, Delta, and JetBlue rely on Tomorrow.io’s intelligence for operational decision-making.

“Our goal is not to replace government weather agencies, but to work alongside them,” said co-founder Rei Goffer. “We want to supply data that’s faster, denser, and more reliable, helping protect communities and economies from growing climate risks.”

And the risks are growing. In 2024 alone, natural disasters caused $320 billion in damages—93% of which were weather-related. With climate instability accelerating, tools that deliver real-time insight are no longer a luxury—they’re a necessity.

Tomorrow.io’s expansion is not just a business milestone; it’s a bold Israeli-led effort to reshape how the world predicts and prepares for natural disasters. With DeepSky, the company is placing Israeli ingenuity at the heart of the global response to climate threats.
