The Espresso Machine principle from 80/20 Sales & Marketing says for every 1000 people who buy a $5 latte, one will spend $2700 on a gleaming stainless steel espresso machine.

This isn’t just a nifty theory, it’s a law of economics. It’s also fractal – a pattern within a pattern within a pattern! This creates the magical compound interest of 80/20 wealth creation.

Perry Marshall’s AI Espresso Machine GPT shows you exactly how much money you’re leaving on the table, and how much more you can make by making a high performance high-end product… without having to find any more new customers.

80/20 says 20% of your clients want to give you 80% of your revenue.

80/20 Squared says 20% of 20% of your clients want to give you 80% of 80% of your revenue. That means 4% of clients generate 64% of your sales.

80/20³ “cubed” says 20% of 20% of 20% of your clients want to give you 80% of 80% of 80% of your revenue.  That means 1% of clients contribute 50% of your sales.

It keeps climbing – 80/20⁴, 80/20⁵ and so on… until there’s only one client left. (That client might be Jeff Bezos.)
