For two decades the advice to founders was build a great product and the rest follows. That advice was correct when shipping software was hard, expensive, and slow. It was a real filter. The people who could ship had an edge over the people who could only describe what they wanted.
AI removed the filter. A solo founder can now produce in a weekend what a funded team produced in a quarter. When the hard part is no longer hard, it stops being where the advantage lives. Isenberg's claim is blunt: code is fully commoditized, product is largely commoditized, and the scarce thing is getting a human to actually use the thing you built.
That is why he reframes the moat. A moat is whatever a competitor cannot replicate cheaply. Code can be replicated in an afternoon now. An audience that trusts you, a community that talks to each other, an email list you own outright, those cannot be cloned by anyone running the same prompt. Isenberg's framing of the new moat is the curated articulation in Gavel's library: build an audience before launching a product, because an audience gives you built-in distribution, market research, and day-one customers. Without one, even a great product struggles to find anyone.
The framework is one sentence with a hard ordering rule attached. Distribution first, product second, always.
