Supports Organization, Role
“[Alexandre Stegner](https://www.linkedin.com/in/alexandre-stegner/ "LinkedIn Alexandre Stegner") (Co-founder & CEO) is also a professor at École Polytechnique and has been doing research in physical oceanography for more than 20 years at [CNRS](https://www.cnrs.fr/ "CNRS"). Working with [Briac Le Vu](https://www.linkedin.com/in/briaclevu/ "LinkedIn Briac Le Vu") (co-founder and research engineer) on the **processing of satellite data to analyze the ocean surface**, they realized that there was a great potential to use them to create value. They were both in a phase where they wanted to change, **to get out of their comfort zone** and embark on the adventure of creating a start-up.”
