+ Method A: ++ Talking to users seems to be the standard advice out of YC. ++ Which places the emphasis on making something no matter how crude and showing it to people who might use it. ++ Then iterating based on what they say. +++ Or better yet on what they do. + Method B: ++ Have deep industry knowledge from experience and solve a known inefficiency or extend the market. + Solving your own problem is a good starting point for both methods. + Users are more validating than White Papers. Good luck.
