OUR BELIEFSWe believe self-help is broken.Most learning platforms are used the same way : consuming generic theories, getting quick highs, ending with no real change.At Paradox, we believe people deserve more.More than content. More than motivation.They deserve a system that knows them, one that adapts, challenges, and grows with them.We believe that every human learns differently, and that technology can do more than entertain or save time.It can translate insight into transformation, through AI personalization, lean experimentation, and deep psychological understanding.Because learning shouldn't just make you feel inspired for a day, it should change how you live, think, and create.OUR VISIONAt Paradox, we want to re-invent how people grow.We do not build another course or coaching app but the Operating System for Greatness.Founded by David Laroche, a creator followed by over 2 million people and known for his interviews with icons like Tony Parker, Mike Horn, Richard Branson, and Gad Elmaleh, Paradox aims to build something that will live beyond any individual (including its founder), for decades to come.Our ambition is to compete with players like Mindvalley (150M ARR), but with a sharper vision, grounded protocols for achievers, people who want more for their life, refusing mediocrity.To do that, we bring together designers, tech, coaches, and filmmakers to create learning experiences that are cinematic, precise, and effective.We move fast, aim high, and hold ourselves to the standards of Apple, Spotify, and MasterClass.
