That seems a bit abstract. It seems impossible to me to just go to a company and say: "Hello, we have absolutely no product to sell (no MVP yet), we just want to talk about your problems and then we'll see if we are building a product. Do you have 1 hour to spend with us?". I guess they just don't take the time to speak about their issues, or in a very artificial way. How to get a real face to face interview with a person willing to share their problems in a constructive manner during 1 hour or 2?
