He graduated from the HEC business school in 1996, specialising in marketing and strategy. For more than 20 years, Julien has had several career paths. He first worked as a strategy and M&A consultant in France and in the UK. He then held several marketing positions of responsibility within the Quadient Group (European leader in omnichannel solutions, logistics and mail processing), in Canada and in France.

In 2012, he started his own business and after a first adventure, launched the website HELLOCASA.FR, a platform allowing individuals to buy and have small jobs and DIY services carried out. It was an immediate success and the company signed partnerships with big names such as Darty, IKEA and the BHV. For several years, Julien and his partners developed and grew the company. By 2020, the team had grown to over 100 people and several thousand service providers in the main French cities. Recently, the company joined the EDF Group to become IZI BY EDF, which has become a key player in energy work and renovation.

Today, Julien works as a consultant and develops several entrepreneurial projects including MonDossierRGPD, the French version of GDPRFolder. His mission is to develop partnerships and online sales in a “vertical” approach (insurance, health, VSE…).
