Scale Economics Shared — The Secret of the Greatest Compounders

Why do Amazon, Costco, and IKEA keep getting bigger despite constantly lowering prices? Most businesses raise prices as they grow. These businesses do the opposite — and that is precisely why they grow. Nick Sleep identified this pattern in 2005 and called it "Scale Economics Shared." It is the operating model behind some of the greatest wealth creation in business history.

Why This Matters

Nick Sleep managed the Nomad Investment Partnership from 2001 to 2014, compounding at approximately 20% per year. He closed the fund at the peak of his success because he believed he had found what he was looking for and wanted to study it deeply rather than manage an ever-larger pool of capital. His investment letters — the Nomad Letters — are among the finest pieces of investment writing ever produced. Sleep spent years trying to understand why certain businesses compounded at rates that seemed mathematically improbable — why Amazon kept growing in the face of relentless competition, why Costco had customer retention rates that a luxury brand would envy, why IKEA could undercut every competitor while continuously improving its product range. The answer was not management genius or marketing brilliance. It was a specific structural decision about what to do with the cost savings that came from operating at scale.
