Thanks to a lucrative deal with YahooMail, file-sharing service YouSendIt now boasts it has surpassed 30 million unique users in the past 12 months.
Fast Company said the company had a 60 percent revenue growth in 2010, but notes:
"Still, while YouSendIt has chosen to highlight total unique users, the real proof of a company's success is its registered and premium usership. Currently, YouSendIt has 400,000 paid subscribers and 18 million registered users--by comparison, Dropbox boasted of reaching 25 million registered users in April."
Main competitor Dropbox passed 25 million registered users in April.
