To reinvent the weather forecast is HD Rain’s leitmotif. Urged by the intensification of extreme climate events and the lack of micro-meteorological data, HD Rain's solution was developed to make individuals, companies and governments more informed, resilient and efficient when dealing with extreme weather events. Founded 4 years ago, by 2 doctors in meteorology and 1 engineer, HD Rain offers very high-resolution weather observations and forecasts for weather-sensitive zones and activities. Innovative at all levels of processes, the start-up opportunistically connects its sensors to lambda TV satellites to generate its data. The loss of signal in rainy days is measured, analyzed and coupled with artificial intelligence algorithms enabling the company to provide observations with a precision of 500m and forecasts of up to 2-hours in advance, both updated minute by minute on its precipitation maps. The system is therefore based on three pillars : 1) Sensors | are autonomous, robust and efficient. 2) System | uses artificial intelligence and deep learning. 3) Data | is high definition, precise and in real time. The 3 pillars combined offer an expert, ultra local and low cost solution to both developed and developing countries. Whether the goal is to add an additional set of data to existing infrastructures or to build up one in areas where weather data is non-existent, HD Rain's added value is multifaceted. The company offers 2 ways of collaboration. In the case where HD Rain sensors are already installed in a given area. The start-up offers monthly data subscription, with different levels of parameters (rain, temperature, humidity, pressure and soon snow and hail), data volume, insight and visualisation tools (web app or API). In the case where HD Rain is not present in the desired area, the start-up offers the opportunity to co-create a personalized project that answers the geographical, budgetary and technical challenges faced by the interested company. HD Rain implements projects in France and internationally, responding to various water-related issues. With a growing international network of 250 robust, HD Rain already collaborates with different clients coming from insurance (classic and parametric), agriculture, energy, water management, and public sectors. 2021, will be marked by HD Rain's massive deployment in the French Mediterranean Arc, with the goal of installing 1 000 sensors. In parallel, the company will keep working on its international projects in the Ivory Coast, Brazil and Georgia, with the hope to grow, widen its client's panel, and always provide the best possible data.
