Caristeo was founded by Frédéric Giuli in 2019. After a 17-year career at Accenture, a major player in international consulting, Frédéric was trained in Climate issues by Al Gore within the Climate Reality Project program.

In 2018, Frédéric decided to dedicate his energy and his consulting expertise to the climate emergency. He creates Caristeo dedicated to raising awareness and transforming companies and organizations.

He is also a founding member in 2018 of an NGO, La Fresque du Climat (climatefresk.org), of which he is now treasurer, Blue Belt and Member of the Board, in order to broaden awareness of climate issues to as many people as possible.
