A company built on the single-layer / best-of-breed model deliberately narrows its scope to one function, one component, or one stage of the value chain — and then invests everything into becoming the undisputed leader at that one thing. The economic logic is simple: depth beats breadth when the function is critical enough that customers will pay a premium for excellence and cannot afford mediocrity.

How It Works
The single-layer model is a deliberate act of strategic subtraction. Instead of building an end-to-end solution that handles every step from raw input to finished output, the company identifies the one layer of the value chain where it can create disproportionate value — and ignores everything else. ARM doesn't manufacture chips. Visa doesn't issue cards. Corning doesn't build phones. Each company owns a single, critical layer and lets partners handle the rest.
The critical insight is that not all layers of a value chain are created equal. In any industry, there are commodity layers where competition drives margins to zero, and there are bottleneck layers where technical difficulty, regulatory barriers, or network effects concentrate value. The best-of-breed player identifies the bottleneck layer and builds an unassailable position there. ARM's instruction set architecture sits inside billions of devices not because ARM is the only chip designer, but because its architecture became the standard that an entire ecosystem of manufacturers, software developers, and toolchain vendors built around.
Monetization varies by layer. Licensing is common (ARM charges per-unit royalties of $0.01–$0.10 per chip plus upfront license fees).
Transaction fees work when the layer processes flow (Visa's ~0.13% network fee on each transaction). Component sales apply when the layer produces a physical product (Corning's Gorilla Glass, sold to OEMs). The unifying principle: the single-layer company captures value proportional to its criticality, not its visibility.

The central tension of the model is dependency without control. You are, by design, a component inside someone else's system. Your customer's product decisions — which materials to use, which standards to adopt, which suppliers to dual-source — directly affect your revenue, and you have limited ability to influence those decisions. The best single-layer companies resolve this tension by making themselves so good, so deeply embedded, and so expensive to replace that the dependency runs both ways.
