When this applies
when evaluating competitors who appear to sell the same type of product, check whether they are actually serving the same customer need or have built fundamentally non-overlapping business models
The takeaway
Don't assume companies in the same product category are actually competing; examine the full business model (scarcity, channel, pricing philosophy, brand meaning) before concluding overlap
Why it works
Two companies can select entirely different value-creation and value-capture mechanisms around the same nominal product category, resulting in disjoint customer consideration sets and non-competition despite superficial similarity
One level up
Category labels are poor proxies for competitive structure; business model architecture is what determines real competition
Where it stops holding
This stops working when customers genuinely do consider both options interchangeable (i.e., true category-level competition exists), making the 'different business model' framing moot.
In their words
The splinter in my mind is that you can sell what on the face of it seems like the same type of products as someone else, but build two entirely different businesses.
