I first met Shawn Carolan and his wife Jennifer at the turn of the century at 11,000 feet. I was hiking with my kids between the Yosemite High Sierra camps. Having just retired from a career as an entrepreneur I had started thinking about why startups were different from large companies. The ideas were bouncing around my head so hard that I shared them with these strangers around a campfire, drawing out the four steps with a stick in the dirt. Shawn immediately said the name I had given the four steps was confusing – I had called it market development – he suggested that I call it Customer Development – and the name stuck. What I didn’t realize was that both were graduate students at Stanford and later both would become great VCs – Shawn at Menlo Ventures and Jennifer at Reach Capital. (And Jennifer is now my co-instructor in the Stanford Lean LaunchPad class.)
