Dr. Prash on Building a $100M+ Crypto Brokerage and Pioneering Psychedelic Therapy

The Part No One Tells - WBGS Yas Grigaliunas (Part 1)

Yas Grigaliunas turned a backyard charity garage sale into Circonomy, one of Australia's most recognised circular-economy companies — years before "circular economy" was even a phrase. In Part 1 of her Perspective X conversation with Pauline Fetaui, she traces the rise: from selling homemade cupcakes at 5am triathlon training and asking herself "how do you raise money without asking people for money," to $15,000 in a single day, to quitting her job with no plan B, to a $4 million raise in four weeks with Officeworks on the cap table. It's also a portrait of the engine underneath: a relentlessly data-obsessed, "burn bright, not burn out" founder who walked into rooms she was told she didn't belong in — including a memorable run-in with Steve Baxter at River City Labs — turned "surprise chain" into supply chain for Officeworks the weekend COVID shut the world down, and built a company on the conviction that idle assets, and overlooked people, are worth far more than anyone assumes. Part 2 is the harder conversation — the cost, and what happened when it all changed. Episode Summary Yas Grigaliunas, founder of World's Biggest Garage Sale and Circonomy, joins Pauline Fetaui for Part 1 of a Perspective X conversation about building a circular-economy company in Australia before the term existed. From a charity garage sale that did $15,000 in a day to a $4 million capital raise in four weeks, Yas unpacks the data discipline, the conviction, and the well-timed moments that turned "dormant goods for good" into a national enterprise — and the energy source that, after 30 years of people predicting her burnout, still hasn't run dry.

From Police Officer to AI Pioneer to Psychedelics: Dr. Catriona Wallace’s Unfiltered Story (Part Two)

From policing the streets of Sydney’s King’s Cross to founding one of the world's first enterprise AI companies, Dr. Catriona Wallace has navigated a career arc that defies convention. As one of the few women globally to list an AI company on the ASX, she scaled Flamingo AI to New York and back, all while raising five children and operating on a frontier that barely had a name. But behind the milestone of a $20M capital raise and the adrenaline of the public markets lay a deeper story of personal cost, identity, and the "sacred wounds" that fuel high-performance leadership. In this deep-dive episode of Perspective X, Dr. Cat shares her unfiltered story of transition: from the corruption and shadow-side of law enforcement to the high-pressure world of venture capital, and eventually, to the jungles of Peru. We explore the "hard thing about hard things," the brutal reality of having your product commoditised by tech giants, and why she chose to sit with ayahuasca the same day she exited her company. This isn't just a talk about technology; it’s a masterclass in the human operating system. We dive into why AI poses a 1-in-10 existential risk, the intersection of ancient ritual and modern innovation, and why Dr. Cat believes the next generation of leaders must undergo a "rapid transformation" of consciousness to ensure humanity isn't left behind by the machines we’ve built.

Dr. Prash on Building a $100M+ Crypto Brokerage and Pioneering Psychedelic Therapy

Win $2,000 in credits with the Day One Network — take our 2-minute audience survey before 30 June: dayone.fm/survey EPISODE SUMMARY 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.

The Hidden Criteria Behind a YC Yes: Yotam on Founder Signals, and the Real Work Behind a Yes

Win $2,000 in credits with the Day One Network — take our 2-minute audience survey before 30 June: dayone.fm/survey 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.
