Moat / 7 Powers Assessment Reference
Purpose: Evaluate durable competitive advantage using Hamilton Helmer's 7 Powers framework (2016) — the field's most rigorous moat taxonomy. A Power is a condition that creates the potential for persistent differential returns; only seven such conditions exist. This reference scores moat durability, distinguishes real Powers from anti-moats, and separates the statics (does the Power exist?) from the dynamics (can we get it?).
Scope Boundary
- compete
moat: structural moat assessment via 7 Powers, durability scoring, anti-moat detection. - compete
matrix(default, elsewhere): feature comparison — features are not moats; do not conflate. - compete
swot(elsewhere): SWOT lists strengths but does not test durability. Moat assessment is the durability filter applied to SWOT strengths. - compete
positioning(elsewhere): positioning maps describe perceived differentiation; moat assessment evaluates whether that differentiation is structurally defensible. - compete
battle(elsewhere): tactical sales ammunition. Battle cards may reference moats but cannot create them. - compete
winloss(elsewhere): behavioral evidence of differentiation. Win/loss tells you what wins deals today; moat tells you what will still win deals in 10 years. - voice (elsewhere): customer feedback. Voice surfaces preference; moats explain why preference persists under competitive pressure.
- field (elsewhere): empirical user research. Field validates customer behavior; moat work analyzes industry structure.
- echo
demand: synthetic-user assumption challenge. Echo[demand] stress-tests moat claims that lack market evidence. - magi (elsewhere): strategic simulation. Magi consumes the moat assessment as input to multi-year scenario planning.
Workflow
INVENTORY → list all candidate advantages (features, scale, brand, partnerships)
→ separate genuine Powers from features and from anti-moats
CLASSIFY → test each candidate against the 7 Powers definitions
→ apply the Benefit + Barrier double test (must pass both)
SCORE → rate Power magnitude (low/med/high) and durability (years)
→ apply the decade test: will this still work in 10 years?
DYNAMICS → identify the origin story: how did the Power form?
→ determine if a missing Power is still attainable (Origins phase)
ANTI-MOAT → flag negative-Power conditions (regulatory, dependence, debt)
→ estimate erosion rate vs investment needed to defend
REPORT → Powers held, Powers absent, anti-moats present, durability score
→ hand strategic implications to Magi; tactical implications to battleThe 7 Powers (Helmer 2016)
| Power | Benefit (to holder) | Barrier (to challenger) | Typical exemplar |
|---|---|---|---|
| Scale Economies | Lower per-unit cost as volume grows | Subscale challenger faces structural cost gap | Netflix content amortization, AWS infrastructure |
| Network Economies | Value to each user grows with user count | Challenger cannot match utility without users | Visa, LinkedIn, Bloomberg Terminal |
| Counter-Positioning | Novel business model superior to incumbent's | Incumbent rationally chooses not to copy (cannibalization) | Vanguard vs active asset managers, Netflix vs Blockbuster |
| Switching Costs | Customer faces real cost to leave | Challenger must compensate for the switching cost | SAP, Salesforce admin lock-in, learned-workflow tools |
| Branding | Customer assigns higher value at same objective quality | Challenger cannot replicate without history and trust | Tiffany, Hermes, Coca-Cola |
| Cornered Resource | Preferential access to scarce input | Challenger cannot acquire the resource | Pixar's brain trust, ARM IP, exclusive licenses |
| Process Power | Embedded organizational/process superiority | Challenger faces hysteresis — slow, hard-to-replicate development | Toyota Production System, TSMC manufacturing |
The double test: a Power requires both a Benefit (improved cash flow for holder) and a Barrier (challengers cannot or will not eliminate it). Either alone is insufficient. A great feature with no barrier is just temporary differentiation.
Durability Scoring Rubric
| Score | Durability | Decade test | Investment to maintain |
|---|---|---|---|
| 1 | <2 years | Will not survive next platform shift | Continuous reinvestment, fragile |
| 2 | 2-5 years | Survives current cycle, fades next | Significant ongoing investment |
| 3 | 5-10 years | Survives one major industry shift | Moderate ongoing investment |
| 4 | 10-20 years | Survives multiple shifts | Compounds with low marginal cost |
| 5 | 20+ years | Generational; new entrant must change category to attack | Self-reinforcing |
Apply the decade test to every claimed Power: "If a smart, well-funded competitor entered tomorrow with the goal of neutralizing this Power, could they do it within 10 years?" If yes, durability is <=3. If no, justify why structurally.
Power Dynamics: Statics vs Dynamics
Helmer separates two questions:
- Statics — does the Power exist in the current state? (Use the 7 definitions.)
- Dynamics — how was the Power created, and can it still be created?
Powers form during specific industry phases (Origination, Take-Off, Stability). Most Powers can only be acquired during Origination — once an industry is in Stability, the windows have closed. This is why incumbents rarely add new Powers and challengers must wait for industry inflection points.
| Phase | Power-formation opportunity |
|---|---|
| Origination | Cornered Resource, Counter-Positioning, Branding (slow build) |
| Take-Off | Scale Economies, Network Economies, Switching Costs (lock-in race) |
| Stability | Process Power (compounds slowly); other Powers rarely form |
Strategic implication: if the industry is in Stability and you hold no Powers, do not strategize toward acquiring one — the windows are closed. Reposition to a sub-segment in Origination, or accept commodity returns.
Counter-Positioning vs Differentiation
Counter-Positioning is the most-misunderstood Power. It is not "we're different." It is a specific structure:
| Test | Counter-Positioning | Mere differentiation |
|---|---|---|
| Incumbent's response | Rationally declines to copy | Will copy if it works |
| Reason for non-copy | Cannibalizes incumbent's existing business | None — would copy if profitable |
| Time-bound | Persists as long as incumbent business persists | Disappears when copied |
| Examples | Vanguard's index funds (active managers cannibalize) | Most "challenger brand" stories |
Counter-Positioning fails the test if the incumbent could copy without self-harm. Most "we are the disruptor" narratives are differentiation, not Counter-Positioning. Apply this filter ruthlessly.
Anti-Moat Identification
Anti-moats are structural conditions that erode returns regardless of operational excellence. Detect early; defending is costly.
| Anti-moat | Mechanism | Erosion signal |
|---|---|---|
| Platform dependence | Host platform captures the value | Apple/Google policy changes, App Store fee shifts |
| Regulatory exposure | Returns hostage to political risk | Pending legislation, jurisdictional rulings |
| Customer concentration | One buyer controls margin | >25% revenue from single customer |
| Talent dependence | Power lives in 1-3 individuals | Founder/star-employee non-replaceable |
| Technology debt | Compounding rebuild cost | Refactor cost approaching new-build cost |
| Reverse network effects | More users degrade experience | Spam, moderation cost growing nonlinearly |
| Disintermediation risk | Buyers and suppliers can connect directly | Marketplace transaction-leakage rate rising |
| AI commoditization | LLMs absorb the workflow | Workflow becomes a one-prompt task |
Anti-moat rule: a single anti-moat can neutralize a Power. Score the net moat as min(Power durability) - (anti-moat severity).
Anti-Patterns
- Calling features "moats" — features without barriers are temporary differentiation. Apply the double test.
- Confusing first-mover advantage with a Power — being first creates no durable advantage unless it triggered a Power-formation mechanism (network, scale, switching cost) during Take-Off.
- Treating brand as a default Power — Branding requires demonstrably higher willingness-to-pay at equal objective quality. Most "brands" are just recognition, not Branding-as-Power.
- Skipping the dynamics question — knowing a Power exists today does not tell you whether you can still acquire one. Map the industry phase.
- Counter-Positioning misuse — labeling any new business model as Counter-Positioning. Test: would the incumbent rationally decline to copy? If they would copy, it is not Counter-Positioning.
- Ignoring anti-moats — a strong Power with a severe anti-moat is fragile; investors and operators routinely overweight Powers and underweight anti-moats.
- Static-only analysis — describing today's moat without explaining how it formed leaves the team unable to defend or extend it.
- Multiple-Power inflation — most companies hold one or zero Powers. Claiming three or more is usually evidence of weak classification discipline.
- Confusing "hard to build" with "hard to replicate" — Process Power requires both organizational embedding and hysteresis. Hard-to-build alone (e.g., complex software) is not Process Power; competitors can also build hard things.
Handoff
- To Magi: moat assessment is core input to strategic simulation, scenario planning, and multi-year capital allocation. Pass Powers held, gaps, and anti-moats with confidence levels.
- To Voice: validate Branding-as-Power claims with willingness-to-pay studies and customer language about trust.
- To Field: design empirical studies to validate Switching Costs (real switching attempts) or Network Economies (utility-vs-userbase curves).
- To Spark: when a Power could be acquired in Origination/Take-Off phase, route the Power-building feature concept as a strategic bet, not a roadmap item.
- To Growth: Branding-as-Power requires deliberate brand investment; route the brand-building program to Growth.
- To battle (compete): tactical implications — which Powers to emphasize in objection handling, which Powers competitors hold against us.
- To winloss (compete): validate Switching Costs claims against actual loss data — if customers switch easily, the Switching Cost is weaker than claimed.
- To Lore: validated moat patterns and anti-moat detections become institutional knowledge for future strategic reviews.
