At 26 Marine founded her own agency to disrupt the art industry: MtArt. With a vision informed by her socialist background, MtArt connects artistic talent with brands, cultural projects and collectors. Creating an international community of art lovers and collectors, the agency works with global organisations and cities as well as the world’s biggest brands, including Apple. Dior and even The World Cup.
Alongside running her agency, today Marine is a writer and keynote speaker on contemporary art and art investment - her talks include two TEDx talks on transforming cities with art and the effect of social media on our minds. She recently published her first book with Penguin: ‘The Visual Detox - How To Consume Media Without Letting it Consume You’.
