CoinOut Gets Coin In

Episode description
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.
