Earthmover wants to become the Snowflake of weather and geospatial data

by | Sep 22, 2025 | Technology

Few things generate as much data as simply observing the Earth from above. But Ryan Abernathey and Joe Hamman very quickly realized that all that data still wasn’t enough for their startup to thrive. Their data-centric, climate tech startup, Earthmover, would need to pivot.

The pivot isn’t entirely away from climate tech, though. Instead, the company is shrinking the time scale, focusing on how climate affects daily life — in other words, the weather.

“What makes a compelling use case for our platform? Data that change frequently,” Abernathey, Earthmover’s co-founder and CEO, told TechCrunch. “That’s where there’s a lot more urgency around solutions. That [data] goes to weather, goes to fire, goes to new observations that are being generated.”

Climate outputs, he noted, are “important, but they’re kind of static,” with new data emerging every few years.

Earthmover’s core product remains its data structure, which was built to handle large, complex data sets. “In geospatial they call it a raster. In AI, they call it a tensor. In old school Fortran, they just call it an array,” Abernathey said. On top of that, the startup has built a range of tools to help customers tease insights out of their data.

The pivot has helped Earthmover find paying customers — more than 10 so far, per Abernathey — and land a $7.2 million seed round, the company exclusively told TechCrunch. The round was led by Lowercarbon Capital, with participation from Costanoa Ventures and Preston-Werner Ventures. The company is using the cash to build new tools atop its data storage platform.

Earthmover is built on open-source software, including Xarray, Pangeo and Icechunk, and runs on major cloud providers, including Google Cloud, AWS and Microsoft Azure, as well as on-premise servers. Both A …
