I respectfully disagree. Technology entrepreneurship is equal parts innovation and selling. Otherwise the entire world would still be using COBOL on an IBM Mainframe and we did be connecting on Gopher instead of the world wide web.
Yes, Go To Market is critical and often key to the success of a venture but it is too limiting to think that it matters more than building a great tech product and disrupting an existing market.
As technology entrepreneurs, it is crucial that we keep balancing innovation and sales. The trick is to understand the balance between the two and to be able to shift gears between a innovation DNA and a customer acquisition DNA within the startup, seamlessly.
