A generation of founders absorbed the wrong lesson from Google. Google made scalability look like the whole game. Founders and investors started optimizing for it from day one. Graham's 2013 essay was the counter-argument. The thing that kills most early companies is not that they cannot scale. It is that nobody is using the product, and the founders are polishing architecture for a load that does not exist.
The reframe is to stop treating "it doesn't scale" as a disqualifier. In the beginning, the unscalable thing is the only thing that works. You recruit users one at a time. You do their setup for them. You show up where they are. None of that survives contact with a million users. That is fine because you do not have a million users. You have ten, and ten is the problem to solve right now.
The canonical example is Airbnb. The founders had an idea, no users and a flywheel that would not turn. So they went door to door in New York and took professional photos of hosts' apartments themselves. Photography is not a scalable feature of a marketplace. It was the unscalable act that made the early listings good enough that the marketplace started to move.
Do Things That Don't Scale is not a license to avoid building a real company. It is a sequencing claim. The manual, embarrassing work comes first because it is the fastest way to learn whether you are making something people want. Automation is a reward you earn after the learning, not a substitute for it.
