Kilgore argues that unfamiliar ideas are easier to understand when related to an existing mental model. The communicator first identifies a mechanism the audience already knows, then uses it as a bridge to the new offer and explicitly marks where the analogy stops. She illustrates the challenge with Beauty Pie: American audiences may understand a buyers' club through Costco, while British audiences may need a different anchor such as Netflix, though that comparison requires qualification because members still pay for products. The bridge is therefore audience-specific. Its purpose is not to claim two things are identical; it gives the listener a place to put the new idea before explaining its distinctive features.
Origin
Kilgore describes repeatedly comparing Beauty Pie with familiar membership models because audiences differed in whether they already understood the buyers' club concept.
Core principles
- 01People interpret novelty through existing mental models
- 02A familiar anchor reduces explanation cost
- 03The differences matter as much as the similarity
- 04The right comparison depends on the audience
How to run it
- 1
Find the comprehension gap
Identify what is unfamiliar about the idea and why the audience lacks a category for it. Separate novelty from ordinary features.
Watch out Do not assume a concept familiar in one country or market is familiar in another.
- 2
Choose a familiar anchor
Select something the audience already understands that shares the new idea's central mechanism. Prefer functional similarity over superficial resemblance.
Pro tip Use the audience's own market and vocabulary.
- 3
State the bridge
Explain the idea as being like the familiar anchor in one specific respect. Keep the initial comparison simple.
Watch out Do not present the analogy as complete equivalence.
- 4
Mark the differences
Immediately explain the features, payment model, or experience that diverge from the anchor. Preserve clarity without creating a misleading promise.
Pro tip Use a short 'like this, except' construction.
- 5
Check placement
Ask whether the audience can now explain where the idea fits and how it differs. Change anchors if the comparison creates confusion.
In the wild
Kilgore describes Beauty Pie as similar to Costco for luxury cosmetics, skincare, and wellness products: members access deals, although the exact model differs. For a British audience less familiar with buyers' clubs, she considers Netflix as another membership anchor but immediately notes that customers still pay for each product.
→ The comparisons give listeners a familiar starting point while preserving the model's important distinctions.
Common mistakes
Using an unfamiliar anchor
An analogy cannot bridge understanding if the audience does not know the reference point.
Hiding material differences
Leaving out where the analogy breaks can create a misleading product expectation.
Is it for you?
Best for
It is best for founders introducing unfamiliar products, business models, or categories.
Not ideal for
It is not ideal when the comparison creates a stronger false expectation than the understanding it provides.

“very often you have to relate it to something existing”
“it's kind of like Costco but for luxury cosmetics and skincare and wellness products”
