The 7 Powers explained: how to tell an advantage that lasts from one a competitor can copy

Hamilton Helmer's seven sources of lasting advantage, the one test that separates them from everything else, and how an owner-led company can use it.

By Dan Lee · November 2026

Ask an owner what makes the company different and the list comes quickly: quality, responsiveness, engineering support, forty years of relationships, a broad product line. Almost everything on that list is real. Very little of it will last. The difference is whether anything stops a competitor from doing the same thing.

That is the core of Hamilton Helmer's 7 Powers. It gives an owner one test to put to every advantage, and a short list of the advantages that pass it.

What Helmer means by Power

Helmer calls a lasting advantage "Power," and it needs two things at once. A benefit: something that raises cash flow through a higher price, a lower cost or less capital. And a barrier: something that stops capable, motivated competitors from copying it. Benefits are everywhere. Every cost program, every good hire and every product improvement is one. Barriers are rare. His advice is to "always look to the Barrier first."

He finds only seven barriers that hold up: scale economies, network economies, counter-positioning, switching costs, branding, cornered resource and process power. If an advantage fits none of them, competitors will eventually match it and the margin it earns will be competed away. Helmer's point is not that those advantages are worthless. It is that they are not a strategy.

The owner's question

"What are we really better at, and will it still be true in five years?"

The second half of that question is where most strategic plans go quiet. A plan that funds advantages anyone can copy buys a few good years. A plan that deepens a real barrier buys margin that lasts. The test tells you which is which.

The seven barriers, in consumer and B2B companies

The same seven barriers show up in both markets, but in different proportions. Consumer companies lean on branding and network economies. Business-to-business companies lean on switching costs and scale, and their "brand" and "network" usually turn out to be one of those two.

Each Power has its own piece in this series, with one consumer company and one business-to-business company that hold it:

Three cautions. In B2B, what gets called "brand" is usually a reputation that exists only with customers who have already bought, which is a switching cost, and a "network" of branches is usually density, which is scale. In consumer markets, awareness is not branding: a company can buy recognition with advertising, but Helmer's branding is a price premium that took years to earn and can't be bought quickly. And in both, certifications, a good app or a popular product are hurdles, not barriers: a funded competitor can match them with time and money.

How to use it with your leadership team

Run this in one working session. It takes about two hours.

1. List the advantages. Write down what you think makes the company different. Then add what customers say, in their words, from win-loss notes, sales calls or interviews. Customers often name a different advantage than management does.
2. Ask the barrier question of each one. If a well-funded competitor wanted this, what would stop them, and for how long? Write the answer next to each item.
3. Match each answer to one of the seven. If it fits none, label it a benefit. Keep it, run it well and stop calling it strategy.
4. Check that the barrier is big enough to matter. A scale advantage counts only if fixed costs are a large share of cost and your volume is well ahead of the next competitor's, not the market's. A switching cost counts only if there is more to sell to customers you already have.
5. Decide where the money goes. Fund the one or two real barriers. Stop spending to promote advantages anyone can copy.

A worked example

Take a composite: a family-owned maker of engineered metal components, about $60 million in revenue, selling to equipment manufacturers. The owner's list of advantages is quality, on-time delivery, engineering support, a broad catalog and long relationships.

Run the test. Quality and on-time delivery are benefits. The two closest competitors are certified to the same standards, and customers say so. The broad catalog is a benefit too: a competitor can add part numbers. Long relationships sound like a barrier but fail when the account changes hands on the customer side.

Engineering support is different. In interviews, customers describe the company's engineers working with theirs at the design stage, so the part is built into the customer's drawing. Moving that part to a new supplier means requalification, test runs and six to twelve months of risk for the customer's engineering team. That is a switching cost, and it pays every time the customer reorders or launches the next version of the product.

The strategy follows. Put engineers earlier into more customer programs. Track the share of revenue on parts the company helped design. Price follow-on business to reflect it. Keep quality and delivery strong, because losing them would hurt, but stop pitching them as the reason to buy.

One limit to plan for: a switching cost resets when the customer redesigns. Each new platform is an open bid, so the design-stage work has to start again at every changeover.

The test works the same way for a consumer brand. Take a second composite: a founder-led specialty food company selling through grocery stores. Its list is taste, clean ingredients, packaging and a loyal following on social media. Taste and ingredients are benefits: a private-label competitor can match the recipe and the label within a year. The following on social media is awareness, which a funded rival can buy. What passes is narrower: a 30-year-old regional brand that shoppers pick over an identical store brand at a 20% premium before they have tasted either. That premium is branding in Helmer's sense. The strategy is to protect it: spend on what keeps the premium (consistency, the story, shelf placement in the home region) and be careful about expanding into categories where the name means nothing yet.

What to do on Monday

Write down your company's top five advantages. Next to each one, write what would stop a competitor from copying it. If you can't name a barrier, you have found a benefit. Then look at next year's budget and see how much of it is going to each.

This pairs with our piece on the onion theory of risk: a buyer in diligence will run this same test on your list.
