It’s official! Dropbox has hit the 100 million users mark. Congratulations to everyone’s favourite free cloud storage solution.

Dropbox founder/CEO, Drew Houston, announced the good news on the Dropbox blog. That’s a pretty huge milestone to hit given the company is just five years old.

Recent valuations of Dropbox are in the $4 billion range, despite a rise in alternative storage solutions from competitors like Box and SugarSync.
