Libin studied the behavior of the earliest adopters and found that the longer customers used the service, the more likely they were to start paying for it. About 0.5 percent convert to paying customers in the first month. But after about a year, 4 percent have converted. (He says he thinks the figure will top out at about 22 percent.)
Libin’s model of freemium won’t work for every company. But it certainly could work for other companies who can retain customer loyalty and make their service more valuable over time while driving down costs. It has convinced him and his investors that giving away the store is the right plan.
“We are committed to being free,” Libin says.
