He was born in Strasbourg, he is 36 years old, looks radiant, and he has just announced the takeover of the American news site Gizmodo on June 5 in New York. Jean-Guillaume Kleis is a discreet, but ambitious press boss. This Alsatian, who lives near Zurich, has been building an international online media group since 2016. His company Keleops, also established in Switzerland, only weighs a few tens of millions of euros, but it is profitable, thanks to an effective marketing recipe.

He first tested the entire battery of digital tools allowing a site to reach its audience and collect income linked to the latter. His project: invest in the acquisition of online media and leverage his know-how.
