The Founder's Notes

Compare

The template only earns its keep if you actually put two cases next to each other.

This is the reason every teardown answers the same questions in the same order. Put a luxury house beside a console platform and the differences stop being vibes — one is refusing sales to protect a price, the other is selling below cost to collect a toll, and both are defending a moat.

Audio · KRX: 005930 (Samsung Electronics)

JBL

A single audio brand stretched deliberately from $30 earbuds to the loudspeaker systems in most of the world's cinemas, owned four times over since its founder's death and now sitting inside Samsung.

Technology · NASDAQ: AMZN

Amazon

Runs a near-breakeven retail operation at enormous scale, and earns essentially all of its profit from renting out the two things that operation forced it to build — computing capacity and shelf placement.

The thesis in one line

JBL put the same three letters on a festival stack and a supermarket earbud, and the brand got bigger instead of smaller.
The store is not the business. The store is the customer acquisition cost for the businesses.

Unit economics

The brand's price ladder, top to bottom

A 2,000x spread between the cheapest and most expensive product carrying the same three letters. The professional tier earns almost none of the profit and does almost all of the work — it is the reason a teenager believes the $30 earbud is a real audio product.

One $50 third-party item sold through Amazon

Amazon captures roughly 38% of the sale price and carries none of the inventory risk. The seller took the risk, paid for the warehouse, and then paid again to be found in a search of Amazon's own catalogue.

What would change her mind

If JBL's flagship consumer line's average selling price declines for two consecutive years while unit volume grows, the price ladder is collapsing downward and breadth has become dilution — at that point the brand is being harvested rather than built, and this becomes a Pass. Equally, if Samsung breaks out Lifestyle Audio and shows JBL growing revenue with expanding margin against Anker and Sony, breadth is proven durable and the case gets stronger, not weaker.
If AWS revenue growth falls below 15% for two consecutive quarters while segment operating margin also declines, the cloud business is being commoditised rather than merely contested, and the capex is being spent defending share rather than buying growth. That combination — decelerating growth and compressing margin at the same time — breaks the thesis outright. A single weak quarter on either measure alone does not.

No mechanisms in common

These two share no tagged mechanism, which usually means the comparison is about contrast rather than pattern — a useful thing to know before you start writing.
