You might have already heard that popular note-taking service Evernote has 5 million members, but did you know that it has 160,000 paying users helping it generate around $800,000 per month? Or that there are 14 published books in Japan dedicated to Evernote?

Phil Libin, the company's CEO, shared a mountain of stats on its growth and revenue with the audience at the LeWeb conference in Paris. Among some of the most interesting data points:

The company's two biggest user bases are in the U.S. (57%) and Japan (20%). Before the end of next year, the U.S. should be in the minority of Evernote's overall pie.

Evernote has 160,000 premium users paying $5 per month. That means, per month, the company earns $800,000 and per year, nearly $10 million. The company didn't disclose its full revenues, which includes a series of confidential, revenue-generating partnerships.

The longer you stay, the more likely you are to become a premium user. While less than 1% of active users sign up for premium content in the first month, approximately 20% of active users (7.5% of total users) are paying users by month 29.

There are 14 books in Japan dedicated to Evernote. On his last trip to Japan, Libin even found an Evernote section.

Evernote is well known for its openness surrounding its stats, but today's stats provide a deeper insight into how the company monetizes its users.
