Founded more than a decade ago in Reunion Island, where vanilla blossoms prosper, our cloud observation and forecasting solutions are now being used daily throughout hundreds of sites worldwide.

In 2023, we’re looking forward to welcoming new responsibilities and to continuing to exceed your expectations. A huge step forward is the availability of improved input data for our satellite-to-irradiance estimations thanks to the launch of the first weather satellite of the Meteosat Third Generation satellite system in December 2022.
We are proud to share our knowledge side-by-side with our prestigious partners: You’re kindly invited to our first event of the year, a free webinar with EUMETSAT, AEMet and Eurisy showcasing the data journey from satellite to solar plants.

The New Year is about new heights and new achievements, new experiences and new acquaintances.
May this year become a great and successful one for you. Happy New Year!
