I think its more about the distribution and customer than the product. If you have those two, a product would come to you naturally. For instance, suppose your father is a dentist. Just take a look at the shitty dentist software they're using. Or maybe some process with dealing with notes, or customers, or whatever. I'm sure some of those processes could be improved through technology. Learn what he needs, build software around that, and try to get in the mindset of a dentist. Expand the network to his dentist friends and go from there. You can do this without have a connection to dentistry but it would be a lot harder. You can build the product, but you'd have a lot of blind spots. Maybe some of the antiquated processes exist that way for a reason. You may not know the mindset of a dentist. Are you just going to go door to door trying to sell to dentists? Figure out what distribution you channel you have access to and focus on that. That's why you see a lot of dev tooling, because devs know how to solicit and sell to other devs. Whereas the intersect of knowledge of dentistry, software background, entrepreneurial risk profile and access to distribution is much rarer, and you can tell by some of their processes.
