AI needs ground truth. We’ve measured it for a decade.
Our world-class AI weather forecasts learn from 3.5 million datapoints measured every day.
Our AI. Our data. Your future.
AI is the new black.
But AI is only as good as what it learns from.
Ten years ago, while everyone else trained their LLMs, we started measuring the weather.
Today, our sensors label 3.5 million ground-truth data points every day — the measured reality that all weather AI is built on.
This has made our proprietary weather forecasts long outperform those of traditional meteorological institutions.

The industries we impact today
We turn advanced weather insights into actionable decisions that move safety, cost and performance.
Agriculture is one of the world's most weather-exposed industries. Every yield, every input and every margin depends on the weather in the field.
It's where Cordulus began, and where our network is most dense. Thousands of weather stations turn hyperlocal weather into the timing that protects crops and lifts output.
At national scale, that means more resilient food production and less waste.
When growers act on measured conditions instead of regional averages, the whole system gets more efficient.
As the world electrifies and shifts to renewables, energy has become one of the most weather-dependent industries on Earth. Generation, demand peaks and grid balance all move with local conditions.
Cordulus delivers reliable weather insights rather than regional averages, so operators can forecast output and balance the grid accurately.
Local weather information turns volatility into something you can plan for.
Construction runs on schedules, and weather is the one thing those schedules can't control. Delays, safety stand-downs and disputes all trace back to conditions on site.
Cordulus brings reliable weather information to the table, so teams can plan around real conditions, protect their crews, and document exactly what happened.
On-site weather data and site-specific forecasts turns weather from a liability into a managed risk.
In motorsport, the gap between winning and losing is often a single weather call. A shower that arrives a lap early or a track five degrees warmer than expected.
Cordulus puts track-specific forecasting in team's hands, turning weather from an unobserved variable into a competitive edge.
Track-specific forecasts vastly outperform regional forecasts in accuracy and take the guesswork out of race day.
Every winter, road authorities balance public safety, tight budgets and environmental concern, and every call is dependent on local conditions that regional forecasts can't see.
Cordulus provides government-approved hardware along with reliable forecasts, giving winter-service teams the necessary data to act at the right time in the right place.
Knowing exactly where and when ice will form changes the economics of winter service.
our partnerships create real impact.
