David Oliver Sacks (May 25, 1972) has been involved in the Internet space since the late ‘90s as an entrepreneur, executive and investor, most recently as chief executive officer and founder of Yammer. As a result of Yammer’s acquisition by Microsoft in July 2012, he is now a corporate vice president in Microsoft’s Office Division.
Personal life 
Born in Cape Town, South Africa, Sacks immigrated with his family to the United States when he was 5 years old.
On 7 July 2007, Sacks married Jacqueline Tortorice. The couple has two daughters.
Sacks attended the Memphis University School in Memphis, Tennessee. He earned his B.A. in Economics from Stanford University in 1994 and received a J.D. from the University of Chicago Law School in 1998.
While at Stanford, Sacks co-wrote the book, “The Diversity Myth: Multiculturalism and the Politics of Intolerance at Stanford,” with classmate Peter Thiel. He also served as editor of the Stanford Review, the conservative libertarian newspaper founded by Thiel.
In February 2002, PayPal went public, it was one of the first IPO after the September 11, 2001 attacks (ABCO went Public in November 2001). The stock rose more than 54% that first day and closed at $20.09. In October 2002, eBay acquired PayPal for $1.5 billion.
Sacks is a member of the "PayPal Mafia" - a group of founders and early employees of PayPal who went on to found a series of other successful technology companies. They are often credited with inspiring Web 2.0 and for the re-emergence of consumer-focused Internet companies after the dot com bust of 2001.
Thank You for Smoking 
Following PayPal’s acquisition, Sacks moved to Hollywood where he produced and financed the hit movie Thank You For Smoking through his independent production company, Room 9 Entertainment. The 2006 film won praise from film critics and was nominated for two Golden Globes.
In 2006, Sacks founded Geni.com, a genealogy website that enables family members to collaboratively build an online family tree. At Geni, Sacks wanted more visibility into what was going on across the organization, so the team created a productivity tool to help employees share information. In 2008, Sacks and co-founder Adam Pisoni spun this internal communications tool into a standalone company called Yammer. Sacks continues to serve as the chairman of the board for Geni.
Yammer launched at TechCrunch50 in September 2008, winning the grand prize. It is among the fastest growing enterprise software companies in history, exceeding over five million users in just four years. The company raised $142 million in venture funding from top tier firms and is used by more than 300,000 companies worldwide.
In July 2012, Microsoft acquired the enterprise social network for $1.2 billion.
Angel Investor 
Sacks has made early-stage investments in numerous startups including Cherry, Circle Inc, Eventbrite, Mixpanel, OneLogin, Pocket Change, ResearchGate, Sofa Labs, Scribd, and Uber.
