The Seven Powers
In 7 Powers (2016), Hamilton Helmer defines Power as “the potential to realize persistent, differential returns” — and identifies exactly seven configurations that produce it. Each pairs a benefit (something that improves cash flow) with a barrier (something that stops competitors from arbitraging it away). A benefit without a barrier is just operational excellence, and it gets competed away.
Per-unit cost declines as volume increases.
The product’s value to each user grows as more users join.
A newcomer adopts a superior business model the incumbent won’t copy, because copying would damage their existing business.
Customers expect a greater loss than gain from switching to an alternative.
Habitual attribution of higher value to your offering, built from long-accumulated information and associations.
Preferential access, at attractive terms, to a coveted asset that independently improves the business.
Embedded company routines and work methods that lead to lower costs or better products, where the main barrier to imitation is the long time required to copy them.
The accessible power
The first six powers depend on conditions most businesses will never meet. Scale and network economies demand volume; counter-positioning requires an incumbent stuck with the wrong model; a cornered resource must first exist to be cornered; branding takes decades and luck. They’re mostly features of a market position you either hold or don’t.
Process power is the exception — the reason Garry Tan calls it the only one of Helmer’s seven that any business can develop. It doesn’t require a market position at all. It accrues to whoever keeps improving how the work gets done, and compounds quietly: Toyota famously gave tours of its factories, yet rivals spent decades failing to replicate the Toyota Production System, because what mattered wasn’t visible on the floor. It lived in thousands of embedded, interlocking routines.
Helmer’s caveat is the discipline here: operational excellence alone is not power — anything easily mimicked gets competed away. Process power is operational excellence plus hysteresis: the routines must be complex and opaque enough that even a competitor watching them run can only close the gap through years of their own commitment.
That’s where AI enters. A well-built AI system encodes a business’s routines, executes them relentlessly, and keeps improving them — accumulating exactly the kind of embedded, hard-to-copy operational depth Helmer describes, on a timescale small businesses can afford. Mapping where those systems belong is the job of the Business Functions Framework.
