After studying medicine, Jean-Claude Madier launched a company specialising in centralised medical offices as well as a network of IT service companies. For his work, he took part in a small trade show for works councils to introduce some professional management software created for this field. It was so successful that he decided to launch a trade show company with the sole purpose of marketing this type of software. Launched in 1987, SCIE was managing thirteen trade shows six years later.
Jean-Claude Madier sold his company to Exposium, which appointed him Institutional Manager and then Division General Manager in 2006. In 2015, he managed 55 trade shows in nine sectors.
