Question
Jeff Bezos was quoted as saying that in the past, success was 30% product and 70% distribution, but now the numbers are reversed.
Answer
Having watched companies build great distribution networks before creating demand, and having watched great products get iterated on to death before ever getting in front of a customer (and then finding out xyz feature isn't important, or critical abc feature is missing), I would say the right answer for YOU will emerge through a customer discovery process. I have yet to see a simpler, faster process for iterating on what your customers want and how to serve them best than Steve Blank's Business Model Canvas: http://www.youtube.com/watch?v=6t0t-CXPpyM.
