"It started with notes hidden under stones, riddles cobbled together on weekends with Max."
Mahé lives in Doussard, on the shores of Lake Annecy, with his 5-year-old son Max. One winter day, through the magic of generative video, he made a pirate ship appear in the port of Doussard. Max saw the real port, empty — and on the screen, the same port, but with a ship anchored exactly where he stood.
The idea of sharing this magic came naturally. Tresorus was born.
