Calm founder Michael Acton Smith on serial failures, mental health, and patiently riding the meditation wave to a multi-billion-dollar app.

Michael Acton Smith — British entrepreneur, billionaire co-founder of the meditation and sleep app Calm, and earlier founder of Firebox, Mind Candy, Perplex City and Moshi Monsters.
Michael Acton Smith traces his journey from a self-described mediocre, introverted student into a serial entrepreneur driven by curiosity, creativity and storytelling. He recounts the rise and collapse of multiple ventures, including the commercially disastrous Perplex City and the platform-shift-driven decline of Moshi Monsters, and the personal toll those failures took on his self-worth and health. His own burnout led him to discover meditation, which sparked the creation of Calm after years of waiting for the cultural 'wave' around mental health to break. He shares hard-won lessons on doing deep foundational work before launching, building real business models, sleep science, and treating nutrition, exercise, mind and sleep as life's foundations. The conversation closes on relationships, communication, vulnerability, and his investment in psychedelic mental-health company Atai.
