Asset-light vs scale economics: the two engines

These businesses turn a little capital into a lot of profit: software, platforms, brands, networks, intellectual property, distribution rights. Once the product exists, serving the next customer costs almost nothing, so margins are high and growth throws off cash instead of eating it. The dream version compounds for years without ever raising much money. Constellation Software, Visa, and the great franchise brands live here. What we look for is a high-margin model where each new customer is nearly pure profit, protected by an edge competitors cannot easily copy.

These businesses start with thinner margins and win by getting bigger. As volume grows, cost per unit falls, the company hands some of that saving to customers, that wins more volume, and the cycle repeats. The flywheel is the moat. Amazon and Costco are the textbook cases: not high-margin businesses, but nearly unbeatable once scale kicks in, because no smaller rival can match the price and survive. What we look for is a real, improving cost advantage, where getting bigger makes the whole machine stronger rather than just larger.
