Who repainted an entire stadium in one night? Set up the biggest cinema screen ever built? Had a 20 m giant walk down the Champs-Elysées? Installed elevators in an Olympic swimming pool to turn it into a restaurant? Who will light up one of the world's tallest towers tomorrow: William Perkins, of course. Sometimes called "the Seguela of events", he is the founder of a new profession that sublimates all the usual techniques of communication, turning them into operational communication. For this art of the grandiose and the ephemeral, the resources deployed are immense and the results magical and spectacular. And all for a single day, a single session, a show that will never be repeated!Whether he's organizing a sales support convention, the anniversary celebration of a global industrial group, or an inauguration ceremony-like that of the World Cup-this director-producer brings together the best professionals to work on his projects. Like so many artists whose talent and works carry the colors of France around the world, this man, modest and secretive in his everyday life, never ceases to make headlines abroad. His sole motivation: "to ensure the success of others".
