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.

Episode Summary

Yotam Rosenbaum never planned to be a startup founder, let alone one of Australia’s most active investors in Y Combinator companies. He started out as a musician, marketing his own band in Los Angeles, until the frustration of promoting music online became the spark for building Earbits, a platform once described as “Google AdWords for music.” What began on a traffic-jammed freeway turned into a five-year journey through Y Combinator, product-market chaos, and a successful exit.

Since then, Yotam has backed over 400 YC startups, built one of the only Australian-led funds inside the program, and helped founders at home think far beyond local markets. He reflects on what actually matters at the earliest stages, why founder relationships trump early traction, and how to spot the quiet signals of a breakout team. There’s also a reality check for anyone raising capital: most investors won’t give you a clear no, and that’s the real cost.

From Craigslist drum lessons to portfolio unicorns, Yotam’s story is anything but typical. But it’s proof that trusting your sense of direction, without needing the whole map, can still get you somewhere remarkable.

Ricky Sevta isn’t afraid of hard truths, or hard problems.

Bryony Cole is the founder of Future of Sex and Sex Tech School, and a global authority on the intersection of sexuality and technology. In this episode, she shares how she left a career in corporate tech to build the sex tech industry from the ground up.

She opens up about the personal rebellion that drove her early experiments, from living in a forest commune to launching a podcast that evolved into a movement. Bryony unpacks what it really took to pioneer a taboo space – from getting censored and locked out of banks, to renting out her apartment to fund live events.

The conversation also explores how AI, loneliness, and digital saturation are reshaping intimacy and identity. Bryony shares her view on what’s coming next – not just in sex tech, but in how people relate to themselves, each other, and the tools around them. She calls it the “Future of Self.”
