What was Greg Cassar's biggest money mistake?
Greg's biggest money mistake was using the era's winning tech platforms to make money without ever owning a piece of them. He was advertising on Google within months of launch, was on Facebook within two months, and did more than $10 million in sales on Amazon — yet he never bought and held the stock of any of them. He was an operator, not an owner.
Why isn't knowing the winner enough?
Spotting the winner is only half the equation. Greg used those platforms brilliantly to grow businesses — and they all worked — but he never asked the owner's question: can I own part of this business, hold the stock, and ride it long term if it's a clear industry winner? Recognising the trend without acting on it left the biggest gains on the table.
How big was the miss?
Amazon rose roughly 318,000% from its 1997 IPO to today — meaning $10,000 invested at the IPO would be worth around $31 million now. It was the biggest of the three, but the pattern was the same across all of them.
Is the same opportunity happening again?
Yes. Greg's point is that the same dot-com-style cycle is now playing out in AI. The takeaway isn't which stock to buy — it's the shift from operator to owner: as the next platform wave plays out, think about owning the winners, not just using them. Then check whether you're actually on track to compound your money over the years ahead.
