Over the last 10 years I've designed, developed, deployed, and managed all of the above for over a dozen different production level applications across several different companies; and each one of these applications started out as a napkin sketch. I'll give examples of how these ideas were turned into products and how these products were turned into revenue. Examples will be drawn from my early days as a developer at Amazon.com, the story of ModernBill from idea to exit, the rise and fall of dnZoom, and Backupify napkin sketches when they were LifeStreamBackup.
