I sell an excel add-in that integrates with some popular trading software. It makes life easier for traders. It has a couple thousand users paying around $10 a month. That's about as specific as I want to get.
It required a little domain specific knowledge to create, and a recognized name among trading forums to initially market. Otherwise it's super simple and I'm continually surprised that there are no real competitors.
