The 25 most successful Facebook alumni of all time

For some, working at Facebook is a career peak. For others, it’s just the beginning.

These 25 Facebook alumni (a number of whom were integral members of the site’s original team) have gone on to invest in and found some of the biggest companies and buzziest startups to date.

Check out what they have been up to since leaving their positions at the world’s largest social network.

Adam D'Angelo started the wildly successful Q&A site Quora.

Position at Facebook: June 2004 - December 2005; CTO, November 2006 - June 2008

D'Angelo was Zuckerberg's high school friend who, according to D'Angelo's LinkedIn page, was in charge of 'random stuff' during his first year and a half at Facebook. He became CTO in late 2006, leading new product development and managing the site's rapidly growing engineering team.

In 2009, D'Angelo founded the Q&A site Quora. D'Angelo's idea of success for Quora? '...If we could double the amount of knowledge available to people on the internet, that would be a really good outcome to me.'

Position at Facebook: VP of platform monetisation, VP of user growth, 2007 - 2011

As the longest-tenured member of Facebook's senior executive team, Palihapitiya helped drive the social network to become one the most important companies in the world. During his four years at Facebook, he was in charge of both mobilization and virality efforts.

Now he's the founder and managing partner of The Social+Capital Partnership, a venture capital fund. He's also chairman on a number of company boards, and in 2011 he became part owner and board director of this year's NBA national champions, the Golden State Warriors.

Position at Facebook: Cofounder, February 2004

Zuckerberg's roommate went on to cofound Jumo, a startup that aims to utilise social media to change the world, which merged with GOOD Inc. in 2011. Prior to Jumo, Hughes served as developer of Obama's campaign website and social media presence during the 2008 Presidential election.

Hughes bought the magazine The New Republic in 2012; his leadership has been met with much public chagrin for shifting the publication's focus to its digital presence.

Ezra Callahan is investing in the hospitality industry.

Position at Facebook: Manager of internal communications and product manager, December 2004 - July 2010

Callahan was hired to 'whittle away' at Eduardo Saverin's CFO responsibilities as the sixth hire at Facebook. Eventually, he was in charge of cultivating the site's corporate identity. When the company went public in 2012, his 0.08% share of Facebook was reportedly worth $US80 million.

Gilles Mischler is an engineer at Dropbox.

Position at Facebook: Site ops engineer, June 2005 - May 2010

The French engineer built and designed Facebook's IT infrastructure from the ground up. After Facebook, Mischler went to Playdom but was only there for a few weeks before the company was acquired by Disney for more than $US700 million -- perhaps that's why he claims on his LinkedIn page that he 'almost' implemented a data center network for Playdom. As of March 2014, Mischler has been working as a network engineer at Dropbox.

Katherine Losse is launching a new startup for wearable-first technology.

Position at Facebook: Customer service, 2005 - 2010

Zuckerberg had chatted with Losse about the two of them writing a tell-all about their experience at Facebook, but soon after Losse sold her company shares and moved to Texas. Eighteen months later she published 'The Boy Kings,' a peek inside the early days of Facebook and her experience as a woman in male-dominated Silicon Valley.

As of August 2014, Losse is back in San Francisco launching Magic Vibes Corporation, a seed-funded tech startup that builds wearable-first technology for the Apple Watch and other iOS devices.

Tim Kendall is a top advertising executive at Pinterest.

Position at Facebook: Director of monetisation, June 2006 - December 2010

Kendall spent his time at Facebook working on product strategy and development for the site's revenue-generating products.

Now he's a top guy at Pinterest, where he recently moved from head of product to general manager of monetisation. This summer he's leading the much-anticipated roll-out of Promoted Pins -- a new way for advertisers to engage with users. Kendall calls it 'the best kind of business model.'

Todd Jackson's startup was acquired by Twitter, where he's now director of product management.

Position at Facebook: Product manager for Newsfeed, Photos, and Groups, October 2011 - October 2012

Yishan Wong recently resigned as CEO of Reddit.

Position at Facebook: Director of engineering, December 2005 - March 2010

Wong came to Facebook after spending nearly five years at PayPal as senior engineering director. His expertise landed him a role in Facebook's internationalization efforts, where he came up with the idea for crowdsourcing translations. He's even listed as an inventor on the patent for community translations at Facebook.

After two and half years as CEO of Reddit, Wong resigned in November 2014, calling the job 'incredibly stressful and draining.'
