About Julio Vasconcellos
Sebastien de Halleux is a serial entrepreneur-operator who co-founded Playfish (one of the earliest social gaming studios), Saildrone (autonomous ocean data drones), and Field AI (field autonomy for robots), giving him hands-on experience building products across consumer gaming, ocean tech, and AI robotics rather than coming from a traditional finance background. He maintains a distinctive philosophy that there is no such thing as a low-quality user, only a low-quality experience, focusing on product quality and user delight over short-term monetization tactics.
