The scan begins by choosing a dominant competitor you do not want to imitate and asking where its standard operating model fails. Candidate categories are then tested against real behavior rather than abstract brainstorming. Observe an unexpected purchase, ask the buyer why it felt acceptable, and probe why existing alternatives were rejected. Next, experience those alternatives personally on both sides of the transaction, looking for trust, convenience, pricing, and presentation failures. Size the market with whatever credible evidence exists, then define the operational capability that would turn the gap into a barrier. The output is not merely an underserved category; it is a category where customer friction is meaningful, demand appears large enough, and the solution requires a system the dominant platform is poorly suited to reproduce.
Origin
Julie Wainwright described looking for a commerce category Amazon would struggle to replicate, then recognizing luxury resale after questioning a friend and personally testing existing selling channels. Extracted from The Foundr Podcast.
Core principles
- 01Start with a structural weakness in the dominant platform
- 02Observe behavior that contradicts category assumptions
- 03Investigate every weak alternative from the customer's perspective
- 04Confirm that the market is large enough before committing
- 05Move quickly because attractive insights rarely remain unique
How to run it
- 1
Choose the incumbent
Name the dominant company whose strengths make direct competition unattractive. Describe the standard model it applies across categories.
Pro tip Focus on structural constraints rather than temporary product gaps.
Watch out Do not assume a large incumbent is incapable merely because it has not entered yet.
- 2
Map model mismatches
List categories where trust, curation, authentication, service, or physical handling conflict with the incumbent's usual model. Keep several candidates until customer evidence distinguishes them.
Pro tip Look for experiences that require judgment or high-touch operations.
Watch out A difficult category is not automatically an attractive business.
- 3
Interrogate surprising behavior
When a customer behaves differently from the category stereotype, ask what made the purchase acceptable and why other routes were rejected. Probe both buying and selling friction.
Pro tip Ask about specific alternatives the customer would never use and why.
Watch out One conversation reveals hypotheses, not representative market demand.
- 4
Experience the alternatives
Use the current buying and selling channels yourself. Record trust failures, inconvenience, poor presentation, pricing pressure, and missing service.
Pro tip Test the least appealing route as well as the obvious digital competitors.
Watch out Do not generalize a single bad interaction without checking whether the mechanism recurs.
- 5
Size the prize
Estimate the reachable market from available transaction data, adjacent platforms, and category economics. Decide whether the opportunity can support the required operating model.
Pro tip Use ranges when the category lacks clean public data.
Watch out A painful customer experience can still sit inside a market too small for the proposed costs.
- 6
Define and build the barrier
Specify the capability that solves the friction and is difficult to reproduce, then begin building it quickly. Treat speed as important because other founders may notice the same opening.
Pro tip Make the barrier operational and cumulative, not just a launch claim.
Watch out Speed without a real barrier can produce an easily copied first version.
In the wild
Wainwright saw a wealthy friend buy used luxury goods from a trusted boutique while rejecting eBay, consignment stores, and consigning her own clothes. Wainwright then tested selling handbags, jewelry, and clothing through existing routes, sized the market, and concluded that online reach plus authentication and service could create a stronger experience.
→ She moved quickly to establish The RealReal around trusted, full-service luxury consignment.
Illustrative application: a founder notices professionals buying used laboratory equipment only from trusted local dealers. Interviews reveal that broad marketplaces lack inspection records and safe logistics. The founder tests both channels, sizes transaction volume, and designs an inspection-and-delivery network that general marketplaces would find operationally awkward.
→ The concept advances only if trust friction, market size, and the hard-to-copy service layer all hold.
Common mistakes
Competing on the incumbent's terms
A slightly prettier storefront does not overcome a dominant platform's capital, traffic, and standard commerce capabilities.
Treating one observation as proof
The surprising purchase should trigger interviews, channel testing, and market sizing rather than immediate certainty.
Leaving the barrier undefined
An attractive category is vulnerable if the solution does not accumulate trust, data, software, or operational capability.
Is it for you?
Best for
It is best for founders exploring commerce or marketplace categories where trust, curation, service, or physical operations matter.
Not ideal for
It is not ideal when the proposed advantage is only branding or a feature that a well-funded incumbent can copy easily.
From the transcript
“I was looking for an opportunity that Amazon could not replicate in the commerce world.”
“And I knew right then the light bulb went on”
“I better execute as fast as I can because someone else will do this also.”
