It all started 8 years ago when he was 22 and decided to cycle around the world to spotlight plastic waste solutions. He understood then how the planet is changing and how storytelling and adventures are a great way to inspire people. Since then Matthieu with his team swam 380km down the River Seine, 110km across the Titicaca lake, 500km in realy in the Mediterranean sea. He shared his story in many conferences including 2 TEDx and is now preparing to swim across the Atlantic.
