Built by people
who take
weather
seriously.

Weatherstem was founded on the belief that the data you act on in an emergency should come from your location, not an airport 20 miles away. Eleven years later, that belief still drives every product decision we make.

How we work

What we care about

Accuracy over convenience

We use your specific location's data because regional forecasts are not good enough for life-safety decisions. The extra complexity of deploying real hardware at your site is a deliberate choice.

📞
We pick up the phone

Every client gets a direct line to a real person on our team. Brandon Fletcher said it best, 30 years in public safety and he had never seen a weather company with such high regard for its customers. We intend to keep it that way.

🌌
Hardware matters

Apps give you someone else's data. Weatherstem gives you a professionally installed station at your location. We believe the physical hardware is not a detail, it is the whole point.

Our story

Started in Tallahassee, deployed everywhere

Weatherstem started in 2014 in Tallahassee, Florida, one of the most lightning-prone cities in the United States. That context matters. The founders did not come from Silicon Valley, they came from a place where the stakes of bad weather data are immediate and real.

Eleven years later, 900+ stations are deployed across 30+ states, serving NFL franchises, Southeastern Conference athletic programs, state emergency management agencies, and distribution operations that depend on Weatherstem every time conditions get serious.

"Weatherstem has been a force multiplier for us. It provides critical weather data to the campus community with little to no effort."
