I enjoyed the article very much and I have the same experience. The reason that my previous startup was successful was the fact that all of my co-Founders had been long-time veterans of their own industry (which they help built in the past 20+ years). No one couldn’t have gotten that important product insight by just talking to customers. Customers know what to object and what to improve when you present them with an imperfect product but not when you present them with a perfect PowerPoint. Henry Ford had said that if he had listened to his customers, he would have built a faster horse because that was what his customers wanted. Similarly, Steve Jobs could not have designed his iPod (and iPhone) had he not been a music fanatic. Entrepreneurs must learn to listen to our hearts if we believe that we are the perfect "surrogate" customer. Good luck, everyone.
