It looks like Dropbox is about to get a new look – or at least a significant refresh.

As expected, Instagram’s lead designer Tim Van Damme has announced that he is leaving the company – and his last day will be Friday. After that, he’ll be heading to Dropbox in early August.

“The past 18 months were some of the best of my life, both personally and professionally. I’ve had the opportunity to work with some of the brightest minds in this business, on an app that transformed the way people interact with each other every single day, and also made a lot of new friends. But it’s time to move on, time to solve a different set of problems,” says Van Damme.

Van Damme first joined Instagram at the beginning of 2012. Before that, he served as an iOS designer at Gowalla.

Last week, Dropbox kicked off their first-ever developer conference. At that conference, the company announced that they now have over 175 million users who are syncing over a billion files every day. That means that the company has nearly double its user base in the past 8 months.

“Dropbox is a fascinating company. It provides value to a wide range of people, not just those who build things,” he says.
