Jean-Luc Fretard

Co Founder
ideation to company

25 years of experience in the creation, development and management of digital solutions and structures. The years spent as general manager, director of innovation or directors in different companies and organizations have forged in me an unshakeable faith in the power of collective intelligence as well as a great acuteness on all innovation and creation brakes . I enjoy sharing my visions at conferences for Markus Evans, TedX or any other forum.

Lucid, pragmatic and committed. I like exploring new spaces through other ways on land, road, sea and air.

My secret sauce for Hola’Up: “Get out of the frame, gain height, master the acceleration and optimize the trajectories towards the goal”

ideation to people

Work Psychologist, Entrepreneurship Coach and mental trainer, I spent 10 years in the conquest of the best potentials and talents of digital and IT for startups with the most innovative services.

I am now specialized in human behavior in search of the wildest challenges! Madness is to behave in the same way and expect a different result as Einstein said.

Passionate about innovation and the human relationships and creativity they bring to life, my role is to support human and technological challenges by making change a wave spot. I listen, I observe, I transcribe, I create the link by facilitating the construction of an objective for a concrete and lasting realization.
