Kirkland House Duo Who Founded Facebook Go Separate Ways, Moskovitz To Make ‘Work Life’ Program

Facebook co-founder Dustin A. Moskovitz announced earlier this month that he was leaving the social networking Web site to found a new Internet company with fellow Facebook engineer Justin Rosenstein.

The new company will develop “an extensible enterprise productivity suite, along with a high-level open-source software development toolkit,” according to a note posted on Rosenstein’s Facebook profile.

“We hope our products will become to your work life what Facebook.com is to your social life,” Rosenstein wrote in the note.

Moskovitz, who founded Facebook in Feb. 2004 with his Kirkland House roommate Mark E. Zuckerberg, acknowledged the networking giant’s influence on his new venture.

Although the new business will be separate from Facebook, Moskovitz wrote in a letter to his co-workers that the company will “feel like a natural extension of Facebook’s product and purpose.”

Facebook will be the default option for identifying users on the new site, and the user interface will be similar to Facebook’s to facilitate easy navigation.

In his statement to his co-workers, Moskovitz wrote that his experience at Facebook will stay with him even after he departs.

“Facebook has been my passion and my purpose for the past 5 years,” he wrote. “I will always bleed Facebook blue.”

Zuckerberg had similarly fond words for his former partner.

“Dustin has always had Facebook’s best interests at heart and will always be someone I turn to for advice,” he said.
