Some good ideas here already. The way I see it good products are born in the intersection of the industry problem space and the technical solution space. Often you will have people in some industry doing something without knowing there is a better technical solution and you have technical people unaware of problems their technology can solve. This is especially true for new technologies that enable new things that couldn't be done with older technologies. == "Disruption"

The best entrepreneur IMO brings a combination of the technical expertise with understanding of the problem, preferably a personal/deep understanding. If you want to understand specific business problems for some specific businesses/industries you need to read about them, talk to people from the industry and/or work in the industry. Some problems are generic and cut across industries. Some b2b problems are the same problems individuals have in performing their work.

Some problems are easy, e.g. have easy solutions, everyone knows about them. Some problems are hard, a lot of work to solve. Some problems are very niche/specific, no one knows about them...
