I could probably name like 6 companies of the top of my head, all of them being in the boat of "call us and we give you our custom software for your business need", where any competent developer can probably come in, look at the use case, and probably write the entire backed in about 2-3 months (and now with LLMs, 3-4 months for front end and backed).

The thing about monetization of software isn't about usefulness, its about marketing, which starts with realizing that the things that are trivial for you to do are way less trivial for others.
