Philippe Ginestet, 66, is the owner of the GIFI and TATI chain of stores. With his fortune estimated at 2.3 billion euros, he is the 27th richest Frenchman. But within the closed club of the great French bosses, he is not the only one. Self-made man, French incarnation of the American dream, his management methods are atypical: motivation seminars organized in his luxurious chalet in Megève, poker tournaments between employees, trips to Las Vegas... A corporate culture pushed to the extreme.
