7 Powers vs moats: how Hamilton Helmer's framework maps to startup moat tests

Hamilton Helmer's 7 Powers framework says a business earns lasting returns only through one of seven sources of Power: Scale Economies, Network Economies, Counter-Positioning, Switching Costs, Branding, Cornered Resource and Process Power. Each needs a benefit and a barrier. Moat Check's ten tests cover about half of these directly and add startup-specific risks.

This guide explains the framework, maps each power to the ten tests honestly (including what our tests do not cover), and suggests how founders and early-stage investors can use both.

What the 7 Powers framework is

Helmer published 7 Powers: The Foundations of Business Strategy in October 2016. The book's site describes him as having "decades of experience as a business strategy advisor, active equity investor and Stanford University teacher" and defines its central idea, Power, as "those conditions which create the potential for persistent differential returns."

The key discipline is that every power has two parts. As Lenny Rachitsky summarizes it in his interview with Helmer: "Power requires both a benefit (e.g. lower cost) and a barrier (e.g. switching costs) that prevents others from imitating or neutralizing that advantage." A benefit without a barrier gets competed away. A barrier without a benefit protects nothing.

The seven powers in brief

The one-line definitions below are from Lenny's Newsletter:

1. Scale Economies: "You can produce something more cheaply than competitors, on a per-unit basis, because of the scale of your operation."
2. Network Economies: "Your product or service provides more value because of how many other people are already using it."
3. Counter-Positioning: "Your business model/strategy is so counter to that of incumbents that if they copied you, it would hurt their own business."
4. Switching Costs: "Your customers can't switch to competitors without bearing a significant cost(s)."
5. Branding: "Your unique brand identity attracts and retains a significant number of customers."
6. Cornered Resource: "You have exclusive access to a vital resource, such as the only rights to a patent."
7. Process Power: "You can produce something more efficiently than competitors, and the competitors can't easily copy the method."

Counter-Positioning: the power most moat lists miss

Most moat lists, including the five sources investors use for economic moats, do not include anything like Counter-Positioning. It is the power most relevant to startups attacking incumbents, because the barrier is the incumbent's own self-interest: copying you would damage its existing business.

Netflix and Blockbuster are the classic illustration. Blockbuster declined to buy Netflix for $50 million in 2000, launched its own online rental service in 2004, and in 2007 ran a "Total Access" offer combining online rentals with free in-store exchanges. After a leadership change, the new CEO "raised the price of online DVD rentals and put an end to the free movie deal." Blockbuster filed for bankruptcy in September 2010. The online model was not hard to build; it was hard for a company with a store network to fully commit to.

Mapping the 7 Powers to Moat Check's 10 tests

Moat Check scores startup ideas on ten tests, each marked pass, partial or fail with one line of evidence (details in our methodology). Here is how they line up.

And three Moat Check tests have no direct equivalent among the seven powers:

Where the mapping is strong

Network Economies and Switching Costs translate almost one to one. Moat Check splits network effects into two tests because, for startups, the hard part is usually starting the network: is there a small, self-contained market (a team, a campus, a niche) it can dominate first?

Where it is partial

Cornered Resource in Helmer's sense includes patents, licenses, unique talent and exclusive assets. Moat Check only tests two startup-relevant versions: data that competitors cannot buy, scrape or synthesize, and a distribution channel rivals cannot simply buy. It does not assess patents or regulatory licenses.

Counter-Positioning has no dedicated test. The closest is competitive resilience: could a rival with $50M and a better AI model, launching in 12 months, fail to win the same users? A counter-positioned startup often passes that test because the most capable rival is unwilling to copy it. The likely-copier analysis also helps: if the company best placed to copy you would cannibalize its own revenue by doing so, that is counter-positioning at work. But Moat Check does not score it explicitly, and founders should assess it themselves.

Where Moat Check does not go

Scale Economies, Branding and Process Power are not tested. That is a deliberate choice for an early-stage tool, not a claim that they do not matter. Lenny Rachitsky's summary of Helmer notes that brand, process power and cornered resources "are rare for tech companies" early on, since the company "is usually too young to have built sufficient brand love or uniquely efficient processes." For a pre-launch idea, there is usually no honest evidence to score them on. For a later-stage company, they should be assessed.

Why Moat Check adds risk tests

Helmer's framework asks what creates Power. Moat Check's extra tests ask what can destroy a young company's chance to build it. For startups in 2026, three threats come up constantly:

• Platform risk. Building on someone else's operating system, marketplace or model means they can absorb your product. Apple has done this often enough to coin the term "Sherlocked".
• AI model dependence. If the product's value is mostly the model, any competitor with API access can match it.
• Leaky relationships. If customers meet through you and then move to email or another platform to pay, you never accumulate switching costs or data.

In Helmer's terms, these are tests of whether a barrier can form at all. Our guide on what happens if a big company copies your startup shows how they played out in real cases.

The time dimension

Helmer's framework includes a "Power Progression" with Origination, Take-Off and Stability phases: different powers become available at different stages of a business. Lenny's summary puts the startup version simply: tech companies often start with Counter-Positioning, then build scale, switching costs and network economies.

Moat Check is designed for the earliest part of that path. Its tiers (no moat, weak moat, defensible, strong moat) describe how exposed an idea is today, and each analysis names one realistic move that would improve its position. A useful way to combine the two frameworks:

1. Before building: use Moat Check's tests to check copy risk, platform risk and whether a network or data moat can start.
2. At launch: ask Helmer's Counter-Positioning question about your most likely copier: would copying you hurt them?
3. During growth: track the benefit and barrier for whichever power you are building, as Helmer prescribes.
4. At scale: add Scale Economies, Branding and Process Power to the assessment.

Applying both to one idea

Take a hypothetical idea: software that lets independent veterinary clinics share appointment availability, so a pet owner turned away by one clinic is booked into another nearby.

Through Helmer's lens:

• Network Economies: plausible. Each clinic that joins makes the network more useful to pet owners and to the other clinics in its area.
• Switching Costs: modest at first, rising if clinics run their scheduling and referrals through it.
• Counter-Positioning: worth asking. Would the large practice-management software vendors copy it? If their business depends on keeping each clinic's data inside their own system, sharing availability across competitors may cut against their model.
• Scale Economies, Branding, Process Power: not relevant yet.

Through Moat Check's tests, the same idea raises different questions: is there a winnable starting market (one metro area where enough clinics can join quickly)? Do bookings and payments happen inside the product, or do clinics just exchange phone numbers? Could the dominant practice-management vendor ship a referral feature in a few months? The two views together give a fuller picture than either alone: Helmer's framework identifies the power to build, and the startup tests identify what could stop it from forming.

Which framework should you use?

Use 7 Powers when you are setting strategy for an established product or evaluating a later-stage company: it is more rigorous about what makes returns persist. Use a startup moat check when you are deciding whether an idea is worth building, or screening early-stage deals, and need a fast view of competitors, the likely copier and the specific risks young companies face. They are complementary, and the overlap (network effects, switching costs, exclusive resources) is where both agree a durable business comes from.
