That’s called product-market fit (PMF), and once any product reaches that stage (in other words: it’s proven that people will spend money in such solution), it’s a race to the bottom in terms of costs/building it cheap.

Unless your market is location-dependent, most of the time the incumbents have waaay more experience, so the only advantage you can bring to the market is a lower price, as the first expansion any incumbent will do is to higher the price band with better quality offerings.

Think about stuff like an Air Fryer. Convection ovens had been in the market for several decades. Someone (Philips? I’m not sure they were the first) proved there is a market for a smaller counter-top convection oven and all of the sudden there are Air Fryers from literally any supermarket brand out there.
