Small executive teams quietly run the world’s biggest revenue engines.

At the top of the ranking sit companies like Amazon and Berkshire Hathaway, both defined by unusually compact senior leadership structures. Amazon’s org chart concentrates power tightly around a small group of level‑1 and level‑2 executives, while Berkshire Hathaway operates as a federation of businesses overseen by a minimalist corporate center. In both cases, scale is achieved without layering executives.

Technology platforms and retail giants show a similar pattern. Alphabet and Apple rely on centralized product and capital allocation decisions, enabling a small executive cohort to influence massive global operations. By contrast, companies such as Walmart and Costco balance scale with operational complexity, requiring slightly broader leadership benches while still maintaining high leverage.

Lower on the list, firms like Bank of America and Johnson & Johnson illustrate the opposite dynamic. Heavily regulated, multi‑line businesses often add executives to manage risk, compliance, and segmentation. The result isn’t inefficiency—but it does dilute revenue per executive. The metric ultimately highlights how organizational design choices shape economic power.
