This is one of the clearest explanations of the difference between building a project and building a business.
The point about developers treating startups like side projects really stood out. Many products don't fail because of bad code. They fail because founders keep optimizing features while avoiding the harder questions around validation, onboarding, retention, and customer behavior.
I also loved the idea that startups are won by learning speed, not feature count. That's something a lot of technical founders discover later than they should.
The sections on scope creep and onboarding were especially valuable. A product that delivers one clear outcome quickly will usually outperform a feature-rich product that confuses users.
This is also why foundersbar.com focuses heavily on validation, MVP clarity, and helping founders prioritize the right things before they spend months building. The biggest startup risk is often not moving too slowly, it's moving fast in the wrong direction.
Great read. Lots of practical lessons for anyone trying to turn a side project into a real business.
