The definitive founder essay on why raw ideas are worth very little and why secrecy is the wrong instinct. Graham's argument reframes protection: your real asset isn't the concept but the compounding work of building it, which no NDA can substitute for.

Entering an unfamiliar industry means you cannot see the walls and dead ends that veterans already know. Dixon explains that a good founder holds a map of who tried this before, what happened, and why, and that this map is what real domain knowledge looks like. It gives you a concrete goal for your research: build the maze map through history, analogy, and direct experience.

It sharpens the difference between a trend that is merely interesting and one that just made a real customer ready to move.
