Weather Forecasting: Can Startups Fill the Gap?
USAWednesday, March 12, 2025
Tomorrow's algorithms were initially similar to NOAA's, which rely on complex equations to simulate atmospheric behavior using the vast amounts of data it collects. More recently, the company has moved to generative AI models that can analyze both publicly available data from NWS and Tomorrow's own satellites to produce insights for its customers. This has allowed the company to automate often-manual decision making and improve access to weather data globally.
The company has also focused on improving data gathering in ways that don't require big hardware investments. For example, it has used radio signals from cell towers to measure weather-related data. This wasn't particularly helpful, but ground radar systems like those used by NOAA cost billions. And while there might be cheaper systems like balloons, they only collect data locally. So even if the company could invest in hundreds of balloons, it wouldn't scale globally.
This led the company to space. In May 2023, Tomorrow launched what may have been the first commercially built weather radar satellite. A second followed later that year and in 2024, the company launched a pair of microwave sounder satellites, which measure temperature, humidity and other atmospheric data. Two more satellites followed in December 2024, bringing its orbital total to six. In the fall, Tomorrow embarked on a pilot project to provide its satellite data to NOAA, which is evaluating it for use in forecasts.
Tomorrow has raised $269 million in venture capital, most recently with a $109 million series E round that closed in 2023. The company declined to state a valuation, but an aborted special purpose acquisition deal that would have taken the company public in 2022 valued it at $1. 2 billion. The deal fell through, Elkabetz said, because market conditions made it clear that raising capital privately was more efficient. The company declined to state its revenue, but Elkabetz said it's grown "very much" since the $19 million it reported for 2021 and that he expects the company to be cash flow positive within the next 12 months.
Despite all of this, Tomorrow is not equipped to replace the National Weather Service's forecasts. The company's satellites and data gathering methods are not a replacement for the vast network of satellites, weather balloons, and ground radar systems that the NWS uses. But with the recent cuts to NOAA, the company may have no choice but to step up and fill the void.
