7 Powers summary: how to test whether your advantage will last

Hamilton Helmer's 7 Powers says a business keeps earning more than its rivals only when it has both a benefit, something that improves its cash flow, and a barrier, something that stops capable competitors from taking that benefit away. He names seven types of advantage that meet both tests, and you use them by writing each claimed moat as a benefit, naming the barrier against your strongest rival, and checking whether your company's stage lets that type exist yet.

Short answer

  • The seven: scale economies, network economies, counter-positioning, switching costs, branding, cornered resource, process power.
  • The test: a benefit and a barrier. A benefit alone is good execution, and rivals will match it.
  • The timing: different types become possible at different stages of a company.
  • The output: which claims are real, which to stop calling moats, and what to build now.

Who should use it, and when not to

Founders, strategy leads, and investors use it when someone says "our moat is…" and nobody has asked what stops a rival. It is also useful for the advantage section of a board deck or an investor memo, and for deciding where a growing company should invest so it has a defensible position when growth slows.

It isn't an inventory of everything the company owns; VRIO does that, item by item. Nor does it judge whether an industry as a whole is profitable; that is the five forces. And it won't tell you what to invent. Helmer is explicit that invention comes first; the powers describe what turns an invention into a lasting business.

The seven powers in plain words

PowerThe benefitWhy rivals can't just copy it
Scale economiesUnit cost falls as volume growsA smaller rival must spend heavily to win the share it would need
Network economiesEach customer gets more value as more customers joinA newcomer starts with a smaller network, so its offer is worth less
Counter-positioningA new business model that serves customers better or more cheaplyCopying it would hurt the incumbent's existing business, so it holds back
Switching costsCustomers keep buying because leaving costs them money, time, data, or workA rival must compensate the customer for that loss
BrandingBuyers pay more for an objectively similar offerThe belief behind the premium takes years of consistent history to build
Cornered resourcePreferential access, on good terms, to something valuable: a patent, a license, a person, a supplyThe access is owned or contracted
Process powerWays of working built into the organization give lower cost or a better productThey take years to develop, so rivals can't copy them quickly even when they can see them

The benefit must be material: large enough to show in profit. Faster support or a nicer design can be real benefits, but if a rival could match them next quarter, there is no barrier, and the book doesn't count them as Power.

When each power appears

Helmer's "power progression" ties advantages to three phases of a business: origination, before it takes off; take-off, when growth is fast and the market is still settling; and stability, when growth has slowed. In interviews he places switching costs in take-off, the window when customers are still up for grabs and share is still moving. He describes tech startups as often starting with counter-positioning, which lets a small company survive incumbents with far more money, then moving on to scale economies, switching costs, and network economies as they grow. The book places cornered resource, with counter-positioning, at origination. Branding and process power come late, because they take years; a young company claiming either is usually describing satisfaction or good execution.

A worked mini example

Illustration: a made-up business; every fact is stated here. Morrow Coffee is a six-year-old roaster that sells beans by subscription. Growth has slowed to a few percent a year, so it is in the stability phase. Its rivals are three specialty roasters and the supermarket brands. It is the largest buyer of one Kenyan cooperative. It claims four moats.

ClaimTypeBenefitBarrierVerdict
Exclusive deal with a Kenyan cooperativeCornered resourceThose beans sell at a 30% premiumA five-year exclusive contract, two years leftPower, with a clock on it
Subscription instead of shelvesCounter-positioning?No retailer marginSupermarket brands could add subscriptions without hurting their shelf sales; two already haveBenefit only
A roasting routine with 4% less wasteProcess power?Lower cost per bagThe routine comes with the roaster model rivals can buyBenefit only
Subscribers renew at 85% a yearSwitching costs?Steady revenueCancelling takes one click and nothing is lostNot a barrier: satisfaction

Only one claim holds, and it expires. Morrow decides to negotiate a longer exclusive term now, while it is the cooperative's largest buyer. It stops calling the subscription model a moat in its investor letters. And at its stage it puts effort into branding its single-origin range, the power stability makes possible, accepting that it will take years.

How to check your own advantage

  1. Set the frame. Write what you sell, to whom, the two to five rivals customers compare you with, and your stage: origination, take-off, or stability.
  2. Write each claimed moat as a benefit. Say how it improves cash flow: a higher price for the same thing, a lower cost, or less investment. If you can't, it isn't an advantage yet.
  3. Classify it. Put each claim into one of the seven types, or mark it as none. A claim that fits none is usually good execution.
  4. Name the barrier against your strongest rival. Write why that rival can't copy or outspend the benefit. "They haven't tried yet" is not a barrier.
  5. Check the benefit is material. Compare its size with the profit gap to rivals, using real numbers or marking the gap to check.
  6. Match it to your stage. Flag claims your stage can't support yet, and the type your stage makes possible that you aren't building.
  7. Decide. Keep real powers protected, stop calling the rest moats, and pick one power to build now, with an owner and a first step.

The durable advantage check skill runs this test on your facts and marks every claim it can't support.

Common mistakes

  • Calling any improvement a moat. Without a barrier, rivals match it.
  • "Network effects" from data or users. It counts only if each customer's value rises as others join.
  • Satisfaction mistaken for branding or switching costs. Branding shows as a price premium; switching costs show as something customers lose by leaving.
  • Testing the barrier against a weak rival. Use the strongest one.
  • Ignoring the stage. Each window closes; take-off is when scale and lock-in are cheapest to win.

Where it comes from

Hamilton Helmer published 7 Powers: The Foundations of Business Strategy in 2016, with a foreword by Netflix co-founder Reed Hastings. Helmer worked at Bain & Company, founded a strategy consulting firm, co-founded the investment firm Strategy Capital, and taught business strategy in Stanford University's economics department until 2018. He has explained the ideas in interviews, including on Acquired and Lenny's Podcast. This page is an independent summary in our own words.

Questions

What are the 7 Powers?

Scale economies, network economies, counter-positioning, switching costs, branding, cornered resource, and process power. Each is a different way a business can keep better cash flow than its rivals for a long time.

What does Helmer mean by Power?

The conditions that let a business earn persistently higher returns than its competitors. In Helmer's framing it needs two parts: a benefit that improves cash flow and a barrier that stops capable rivals from taking it away.

Is a moat the same as a Power?

Close. Helmer has said the word moat makes people think mostly of the barrier. A Power also needs a material benefit; a barrier around something that doesn't improve cash flow protects nothing.
