““Evernote’s CEO Phil Libin shared some revealing insights about how the company turns non-paying users into revenue generating ones.[xxiii] In 2011, Libin published a chart now known as the “smile graph.” With the percentage of sign-ups represented on the Y-axis and time spent on the service on the X-axis, the chart showed that, although usage plummeted at first, it rocketed upward as people formed a habit of using the service. The resulting down and up curve gave the chart its emblematic smile shape (and Evernote’s CEO a matching grin). In addition, as usage increased over time, so did customers’ willingness to pay. Libin noted that after the first month, only 0.5 percent of users paid for the service; however, this rate gradually increased. By month 33, 11 percent of users had started paying. At month 42, a remarkable 26 percent of customers were paying for something they had previously used for free.””
