The beauty of Evernote's business is that continued use results in increased likelihood to pay:
About 0.5 percent convert to paying customers in the first month. But after about a year, 4 percent have converted... The shoebox of data is more valuable to the customer as it becomes larger. In addition, compelling uses — like photographing those business cards — quickly eat up the monthly allotment of memory, inducing a person to start paying.This is similar to Google's gmail / storage strategy, but seems more direct and more effective.
But one thing nags at me. What happens if Evernote runs out of money or parks their cash with the next Bernie Madoff?
It's almost as if the business model works too well if it works well: if Evernote makes it so easy to store things, you will store a lot of things. That will in turn make you nervous to keep storing things there. In other words, if your data becomes so valuable to you that you're willing to pay monthly fees to store it, at some point doesn't it become so valuable that you fear keeping it at Evernote?
