The predictive power of
BIG DATA for your business

Get high-definition weather maps with the HyperCast weather software, and minute-by-minute, street level data streams with the Microweather API.


Developing countries lack very basic weather data that could save lives. It's our mission to use new hypersensing technologies to bring critical weather data to every corner of the world.

The Boston-based company’s service has broad applications across government and business, offering ways to better prepare for the increasing number of severe weather events that are occurring worldwide.

To that eternal question “How’s the weather over there?” a Boston startup can give you an answer — literally, block by block.

The technology now appears ready for primetime. It could lead to more precise flood warnings — and more accurate storm predictions if the new data are integrated into modern weather forecasting models.

ClimaCell’s software…can track the intensity of rainfall on one street versus another in the same neighborhood.

To get better data than what NOAA provides, you’d need to invest billions of dollars to build out a new layer of sensors. Or hire teams of Ph.D.s doing some magical data science. Boston-based startup ClimaCell had a better idea: software.

Microweather for every industry. Every Activity.
