The audit separates a platform's visible growth from its underlying strategic power. First, determine exactly how transactions create economic value and how that value changes when more participants join. Second, analyze each customer group independently because buyers, sellers, creators, advertisers, and other participants may perceive and optimize value differently. Third, identify what stops a competitor from matching the platform's value proposition. This final inquiry must examine differential scale, the shape of diminishing returns, switching friction, contractual restrictions, and multi-homing. A platform has power only when it creates a material benefit and possesses a durable barrier that prevents competitors or customers from arbitraging that benefit away. The method therefore converts a vague claim about network effects into a participant-level assessment of value creation, perception, and defensibility.
Origin
Hamilton Helmer and Chenyi Shi developed the framework while extending Seven Powers to complex platform businesses and presented their work in progress on Acquired.
Core principles
- 01Separate value creation from value capture
- 02Measure how participation changes platform economics
- 03Evaluate value from each customer group's perspective
- 04Treat competitive equivalence as the core barrier question
- 05Analyze each platform's idiosyncratic market structure
How to run it
- 1
Map the transaction system
Identify the intermediary, every participant group, and the transaction being facilitated. Describe what each side supplies, receives, and optimizes for.
Pro tip Model materially different use cases as separate customer segments, even when they use the same product.
Watch out Do not assume all buyers or sellers perceive value in the same way.
- 2
Locate economic value creation
Specify how the platform improves matching, discovery, transaction execution, utilization, price, or another economic outcome. Quantify the improvement where possible.
Pro tip Compare the platform transaction with the best realistic off-platform alternative.
Watch out Growth or engagement alone does not establish economic value.
- 3
Plot value against participation
Determine how the economic benefit changes as more participants join each side. Examine whether returns remain material or flatten quickly after reaching sufficient density.
Pro tip Pay particular attention to transaction heterogeneity because greater heterogeneity can make additional scale valuable for longer.
Watch out Do not assume network benefits grow linearly.
- 4
Model perceived value by group
Write the economic equation each participant implicitly uses when choosing the platform. Include revenue, price, convenience, search costs, risk, and operating costs relevant to that group.
Pro tip Interview customers about the alternative they would actually choose, not an abstract competitor.
Watch out Platform-wide averages can hide segments with weak attachment or little perceived differentiation.
- 5
Test competitive equivalence
Ask whether a competitor could deliver a materially equivalent value proposition. Consider copied features, equivalent supply, customer data, accumulated knowledge, and relative scale.
Pro tip Run the analysis separately for every important participant group.
Watch out A platform feature is not a barrier merely because competitors have not copied it yet.
- 6
Stress-test multi-homing
Assess the cost for each group to use multiple platforms or transact directly. Determine whether multi-homing combines nominally separate platforms into one effective participant pool.
Pro tip Include meta-search and integration tools that reduce the friction of comparing platforms.
Watch out Frictionless multi-homing can arbitrage away a large platform's differential value.
- 7
Conclude benefit and barrier
State the material benefit created by the platform and the mechanism that sustainably prevents equivalence. If either is missing, classify the platform as valuable but not yet powerful.
Pro tip Document what evidence would falsify the power conclusion.
Watch out Do not confuse product-market fit, rapid scaling, or a flywheel with durable power.
In the wild
More local drivers can reduce passenger wait times and driver downtime, but the benefit flattens after both services reach adequate density. If riders and drivers can frictionlessly open both apps, they contribute to a shared effective pool and arbitrage away much of either platform's scale advantage.
→ The audit reveals strong value creation but a difficult barrier problem caused by diminishing returns and multi-homing.
YouTube matches viewers with highly varied videos across language, subject, creator personality, music, and production style. Its content scale, viewing history, subscriptions, and watch-time data reduce search costs and improve recommendations in ways a fresh copycat cannot immediately reproduce.
→ High preference heterogeneity keeps additional scale valuable and accumulated information makes competitive equivalence harder.
Common mistakes
Treating every network effect as power
A network effect describes value created when participation affects others. Power additionally requires a durable barrier that prevents competitors from matching or arbitraging that value.
Ignoring diminishing returns
Additional participants may stop improving outcomes once a platform reaches sufficient density. Two competitors operating on the flat part of the curve can provide effectively equivalent value.
Averaging unlike customers
Different participant groups and use cases optimize for different outcomes. A single platform-wide value statement can conceal the segment that undermines the power thesis.
Is it for you?
Best for
It is best for founders, operators, and investors evaluating marketplaces or other transaction intermediaries.
Not ideal for
It is not ideal for businesses that do not mediate transactions between distinct participants.
From the transcript
“So, number one, how is economic value created on your platform? And how does that value change as your platform becomes larger or has more…”
“And the third question is, what is preventing your competitors from getting to equivalence in that value proposition?”
“So the first question is the benefit, and the third question is the barrier.”
