Sylvain Bonnet is a seed investor in La France focused on Apps and Messaging. THE FOUNDER: SYLVAIN BONNET Being an entrepreneur runs in his blood - he founded his first business at the age of just 23! He initially honed his talents in direct selling, in the cosmetics and new technology sectors. In 2003, he and a team of experts embarked on a quest to find a new way of keeping slim for the long term. He founded Beautysané andfocused his research on the '3 Wells': eating well, exercising well and well-being. In April 2013, Sylvain Bonnet and Professor Josette Dall’Ava Santucci published the book “Vivre mince, mieux, plus longtemps” (“Live slimmer, live better, live longer”). This self-help book is overflowing with advice and handy tips on how to eat better, exercise better and feel good. The same year, he also began to present the TV programme “Dérégimez-moi”, on the IDF1 channel in France. It was the first such programme that invited guests to speak openly about diets and nutrition. Bursting with ideas and drawing on his experience, he participates actively in national and international think tanks, exploring the nature of the business of tomorrow.
