Searching for what to solve becomes far more important than how to solve it. Which niche you serve, how underserved the problem is, how quickly you build a solution, and how fast you iterate based on user feedback become the real differentiators. As a problem gains popularity, competitors will enter at an increasing pace, and the product’s price will be competed down to the bare minimum. At that point, the only real advantage for a builder is to be a serial builder for deep niches, spotting them faster than others and delivering quality product to users before anyone else.
