About us

At the crossroads of numerical hydroclimatology and artificial intelligence

Magali and Adrien have both been in office for a few years. Adrien works in Rimouski, on the banks of the Saint Laurent. He carries out field campaigns, swell measurement, and works on marine submersion and wave climate modelling. Magali has a position at the ETS (Ecole de Technologie Supérieure) in Montreal, where she works on coupled hydrology-climate modeling and climate change impact on water resources.

Passionate about their jobs and complement one other, the project is taking seed in their mind to go beyond the stage of university research to move the lines and try the adventure of entrepreneurship. After a few meetings and exchanges with entrepreneurs and water stakeholders, they decided to take the plunge.

Our goal

Reliable information on physical climate risk for all

Hydroclimat is set the goal of enabling all companies and communities in France, Europe and beyond to get relevant and reliable information on physical climate risk. The goal? That all companies and communities can secure and guide their investments and their long-term economic development, thus limiting the climate risk of transition and liability.

Our technology

Using data to identify, assess and reduce risks

The data is useful for understanding climate events and therefore anticipating climate risks. By collecting, cross-referencing, aggregating, post-processing billions of climate data from the scientific community, we produce and provide reliable data of high value. Reliable data ensure true and accurate risk identification. As a result, we offer an intelligible and robust vision of the expected climate change impacts at the local scale. Most importantly, Hydroclimat makes towards building confidence in climate change risk assessment.

We create innovative numerical technology-based solutions that contribute to sustainable development. Our M3E© proprietary technology is the cornerstone in POP-Risk. M3E© is a disruptive technology qualified as DeepTech by BPI France (French Tech Emergence grant). Indeed, M3E© is at the crossroads of the state-of-the-art research in:


Data science, multi-sources, big data and AI


Numerical simulation, multi-model, statistical processing, and ensemble systems


Climate science, hydrology, hydraulic, and climate change


Exposure, risk, and vulnerability to climate change

Building on our experience in North America, we combine our expertise in climate change, water resources and flood with technical cutting-edge skills in numerical modeling to develop POP-Risk. Above all, our « Tech For Good » POP-Risk is designed to answer one of the major challenges of the 21st century: Adaptation to Climate Change.
