From surgeon to psychiatrist, Bitcoin investor to billion-dollar crypto brokerage founder, Dr. Prash Puspanathan has lived one of the most unconventional founder journeys in tech. After co-founding and scaling Caleb & Brown into a global crypto powerhouse, later acquired by SwiftX in 2025, Dr. Prash is now pioneering the future of mental health with Enosis Therapeutics, using VR to transform psychedelic-assisted therapy integration. In this episode of Perspective X, Dr. Prash shares how a single psilocybin experience completely reshaped his worldview, steering him away from surgery and into psychiatry, entrepreneurship, and eventually, crypto. He reveals the parallels between fiscal freedom in decentralized finance and cognitive freedom in mental health, the scrappy early days of arbitrage trading, and the challenges of scaling a white-glove brokerage to serve high-net-worth clients worldwide. We also dive into the future of psychedelic medicine, why integration is the “real work,” how technology can lower costs and increase access, and why prevention, not just treatment, will define the next era of mental health. From paradigm-shifting psychedelics to building billion-dollar ventures, this is a conversation about liberation, of thought, finance, and human potential.
