Facebook acquires file-sharing service

The New York-based start-up has close ties to Facebook going back to its early days; founder Sam Lessin, a college classmate of Mark Zuckerberg's, will be joining Facebook.

Facebook has acquired most of the assets of, a New York-based start-up that lets users privately and sporadically share files through a drag-and-drop interface with additional options like phone calls and even faxing, the company announced Friday on its blog.

Founder Sam Lessin will be joining Facebook full time.'s service, meanwhile, will be shutting down, making this yet another "acqui-hire" on Facebook's behalf--buy a start-up primarily for its founder, and put that new hire to work developing a new feature at Facebook or improving an old one.

"In the coming weeks, we'll be winding down the service. As of this week, people will no longer be able to create new free drops, but you'll be able to download content from existing drops until Dec. 15," the post on's blog explained. "Paid user accounts will still be available through Dec. 15 and paid users will be able to continue using the service normally. After Dec. 15, paid accounts will be discontinued as well."

Facebook's ties to run deep. Lessin had attended Harvard University along with Facebook founder Mark Zuckerberg, and David Kirkpatrick's book "The Facebook Effect" describes him as a crucial player in Facebook's early days: "At the end of the (spring 2004) semester, Lessin, whose father was a well-known investor, took Zuckerberg around New York to meet with venture capitalists and executives in the finance and media industries," Kirkpatrick describes on page 41 of the exhaustive Facebook biography.

Lessin had also, sources say, been an instrumental dealmaker in Facebook's acquisition of Hot Potato, a mobile "check-in" service that it bought earlier this year and in which Lessin had been an angel investor. Similarly, Hot Potato had shut down and Shaffer joined Facebook, where earlier this month he unveiled its new Groups product.

Facebook confirmed to CNET that Lessin will switch coasts and move to Facebook's main headquarters in Palo Alto, Calif., as Shaffer did.

"We can confirm that we recently completed a small talent acquisition for and acquired most of the company's assets," a statement from Facebook read. "We're thrilled that Sam Lessin will be joining us at Facebook."

A price for the acquisition of, which had raised a round of Series A venture capital from RRE Ventures and DFJ Gotham, wasn't disclosed.
