Hamilton Helmer's 7 Powers vs Michael Porter's Five Forces
Comparing Hamilton Helmer's 7 Powers with Michael Porter's five forces and competitive advantage: how they differ, where they overlap, and when to use each.
Anyone studying why some companies hold their advantage for decades meets two frameworks: Michael Porter's five forces and competitive advantage, and Hamilton Helmer's 7 Powers. They are often compared because both try to explain durable returns, and because Helmer's list sounds like a more specific version of what Porter began.
What is the core difference?
Porter asks what makes an industry profitable and how a firm can position within it. The five forces describe the pressures on returns, and the generic strategies describe broad ways to respond.
Helmer asks what specific advantage a business has that lets it earn better returns than rivals for a long time. His answer is a list of seven powers, and a test: a power needs both a benefit and a barrier.
The first is a map of the field. The second is an inventory of what a particular player owns.
What does Porter say?
Porter's Competitive Strategy (1980) introduced the five forces: rivalry, the threat of new entrants, the threat of substitutes, and the bargaining power of buyers and suppliers. Competitive Advantage (1985) added the value chain and the generic strategies of cost leadership, differentiation, and focus.
His discussion of entry barriers lists economies of scale, product differentiation, capital requirements, switching costs, access to distribution, and cost advantages independent of scale. In What Is Strategy? (1996) he stressed trade-offs and fit among activities.
What does Helmer say?
Hamilton Helmer, founder of the strategy advisory firm Strategy Capital, wrote 7 Powers (2016). He defines power as the conditions that create the potential for persistent differential returns. For each of seven powers, he requires a benefit that improves the firm's returns and a barrier that makes it hard for rivals to follow.
The seven are scale economies, network economies, counter-positioning, switching costs, branding, cornered resource, and process power. Counter-positioning means a newcomer adopts a better model that an incumbent will not copy because it would damage its existing business. Helmer's book is a practitioner's account that draws on case examples.
How do they compare?
| Dimension | Helmer | Porter |
|---|---|---|
| Level of analysis | The individual firm | The industry, then the firm's position |
| Core structure | Seven powers, each with a benefit and a barrier | Five forces, value chain, generic strategies |
| Central question | What lets this business earn persistent excess returns? | What shapes returns here, and where should we stand? |
| Overlaps | Scale, switching costs, branding | Entry barriers such as scale, differentiation, switching costs |
| Distinctive ideas | Counter-positioning, process power, cornered resource | Five forces, trade-offs, fit among activities |
| Evidence | Case examples and practitioner experience | Academic framework from industrial organization |
| Best known for | 7 Powers (2016) | Competitive Strategy (1980), Competitive Advantage (1985) |
When does each one fit?
Porter fits when you are entering or judging an industry, comparing positions, or checking where pressure on margins comes from. It is especially useful at the start of an analysis.
Helmer fits when you already know the business and want to test whether its advantage is real and durable: for an investor assessing a company, or a founder asking what they are building toward.
When the industry itself is unclear, start with Porter. When the advantage is the question, Helmer's seven tests are more granular.
What does this look like in practice?
Consider an online marketplace. A five forces view shows buyers with low switching costs, many substitutes, and moderate rivalry. That is the field.
Helmer's questions then ask what the marketplace itself owns. Does it have network economies, where more sellers attract more buyers? Is there a cornered resource, such as exclusive supply? Is there process power, a hard-to-copy operational capability? For each, the benefit and the barrier must both be shown. If neither can be named, the advantage may be weaker than it looks.
"Here is the business: [describe]. For each of Helmer's seven powers, say whether the business has it, what the benefit is, what the barrier is, and what evidence supports it. Be skeptical: where benefit or barrier is missing, say so. Then summarize which one or two powers are most credible and what could erode them."
Why it works: requiring both benefit and barrier removes claims of advantage that rivals could match.
Can you use both together?
Yes. A sensible sequence is to map the industry with Porter, then test the firm against Helmer's powers, then return to Porter's view of trade-offs and fit to decide what to do next.
The shared weakness is that both can become checklists. The useful work is in the evidence for each claim.
"For [business] in [industry], summarize the five forces in one line each. Then identify which force the company's strongest power most directly protects against, and which force is most likely to erode it. Finally, name one decision the company should make now that follows from the combined view."
Why it works: linking each power to a force turns two separate lists into a single argument.

Where to go next
Hamilton Helmer and Michael Porter both sit in the Business Strategist category. For the originals, read 7 Powers by Helmer and Competitive Strategy by Porter, and note that the author also runs an advisory business.

Frequently asked questions
How are the 7 Powers different from the five forces?
The five forces describe the pressures that shape profitability across an industry. Helmer's 7 Powers describe the conditions that let a particular business earn persistently better returns than its rivals. One reads the industry, the other asks what a specific firm owns that rivals cannot easily match. They answer related but different questions. Both are best read in the original, since summaries flatten the conditions each author attaches to the ideas.
What are the seven powers?
In 7 Powers (2016), Helmer lists scale economies, network economies, counter-positioning, switching costs, branding, cornered resource, and process power. For each, he requires a benefit that raises returns and a barrier that keeps rivals from copying it. His book also explains how the powers tend to emerge at different stages of a business. For example, a company might have scale and still lack a barrier if rivals can reach the same scale cheaply, which is why the test has two parts.
Does Porter cover the same ground?
Partly. Porter's discussion of barriers to entry includes economies of scale, product differentiation, switching costs, and access to distribution, which overlap with several of Helmer's powers. Helmer's list adds ideas such as counter-positioning and process power and organizes them around benefit and barrier. The vocabulary differs, and so does the aim. That overlap means Porter's entry barriers are a useful companion when you want to see where a given power comes from.
Is Helmer replacing Porter?
No. Helmer builds on the tradition of strategic analysis rather than discarding it, and offers a more granular, firm-level list. Many practitioners use Porter's industry view alongside Helmer's power-by-power checklist. Neither author presents the other as obsolete, so treat them as different lenses. Neither framework is presented as complete, and both authors expect their ideas to be tested against evidence from the business at hand.
Which is easier for an investor or founder to apply?
Helmer's list gives a checklist of seven questions about a specific business, which many founders and investors find concrete. Porter's five forces give a structure for judging an industry. A founder might use Helmer to ask what they are building and Porter to ask where they are building it. This is an observation about usage, not a documented ranking. In practice the two questions complement each other: where am I building, and what am I building that others cannot copy?
Can AI help me test a power?
It can help you list evidence for each power, draft the benefit and barrier for a business, and challenge weak claims. It cannot verify your numbers or what rivals can do. Give it real data, ask it to argue the opposing case, and treat conclusions as hypotheses. Ask it also to suggest what evidence would disprove each power, which keeps the exercise honest instead of hopeful.
