CEO & Owner


Work →

Guillaume Marien has worked in the design and VFX advertising industry for over 15 years. Shortly after joining SPARX in 2002 as co-CEO and executive Producer, Guillaume decided to create MATHEMATIC. His intention was to establish a new vision of post-production dedicated to high end, creative vfx with a specific focus on art direction.

With two studios based in Paris and a third just recently opened in Montreal, Mathematic has had an overwhelming success both in the French and international creative markets. The work produced for advertising, music video, broadcast design and now feature and documentary films have won critical acclaim in some of the industry’s most prestigious award shows and festivals, including MTV Music Video awards, the Grammy’s, D&AD and Cannes advertising festival to name just a few. Since 3 years Mathematic has steadily been developing a portfolio of work in feature, independent and documentary films. Recent projects include Creative Control, which was awarded best visuals at SXSW, Seuls, an epic sci fi film produced with Canal + and 
Swagger which Guillaume co-produced and which was nominated in 2017 for a Cesar for best Documentary film. With many more projects on the horizon Mathematic has a strong team of just under 100 people.
