While studying at the Paris-Dauphine University, Quentin founded his first company, a computerisation consulting firm, to help deploy the Macintosh.
At 24 he published Finance: financial analysis and forecasting, in which he developed a new forecasting model which led him to hold numerous conferences. He later joined Martichoux and Associates in 1990, which he left in 1997 to found Mandragore, a consulting firm that he would run for 10 years.
Passionate about technology and innovation, he specialised in growth strategy, working for major firms in the tech industry. In 2007, Quentin realised his dream of founding a high-tech audio company. Quentin brings to the company his strategic vision and global ambition.
