Artist and accountant, Matthieu multiplies projects and develops an artistic approach for which numbers play an important role. After several years spent traveling with his family in the French-speaking islands, he moved to Montreal at the age of 17 to begin a North American life. It was 10 years later that he decided to start his own business as a professional accountant able to dedicate time to his artistic practice and that of others. Soon MTLight came along, a collective structure capable of bringing together several people to create graffiti mapping and augmented reality.
