There is still a huge demand for b2b software and large swathes of industry that are in the very early stages of digitalisation. We work in an old fashioned industry (education) and are constantly asked to build x, y & z outside of our scope. Get to know businesses and their problems and there are plenty of opportunities to build helpful software. You will constantly be battling to stay product-based vs service-based but if your building a small company this isn't as big a problem as it seems (Ive met more well off entrepreneurs with service-style businesses) I think the best assistance you can give yourself is to reduce your personal expenses and save up a nest-egg that would allow you to work on this for quite a bit longer than you would think. While saving up, go out and talk to people about their problems. You'll find there are a million problems to which the current solutions aren't a perfect fit. PS If you run a business you will be thinking about money far more than you are now!!
