It’s always fun to see what happens to my students after they leave class. Jeff Witten started CoinOut four years ago in my Columbia University 5-day Lean LaunchPad class. CoinOut eliminates the hassle of getting a pocket full of loose change from merchants by allowing you to put it in a digital wallet. Jeff just appeared on Shark Tank and the Sharks funded him. We just caught up and I got to do a bit of customer discovery on Jeff’s entrepreneurial journey to date.
