BREAKING: Ari Greenburg has been named President of WME, it was announced internally at the agency. In his role, Greenburg will oversee daily operations of WME across its Beverly Hills, New York, Nashville, London and Sydney offices.

Greenburg was one of the first employees of the Endeavor talent agency in 1995 and was the first trainee promoted to agent at the upstart agency. Seven years later, he became the first homegrown partner at the firm. As part of the Executive Committee at Endeavor, Greenburg helped lead the agency’s physical expansion, and ultimately its merger with the William Morris Agency in 2009 to form WME.

Greenburg started in the television sphere, and played a critical role in the growth of WME’s television department, spending 20 years as a television packaging agent, orchestrating record-breaking deals for clients such as Amblin Partners, Greg Berlanti, Dan Fogelman, Michael Green, Carlton Cuse, Adam Horowitz & Edward Kitsis, Brian Koppelman & David Levien, Shawn Levy, Rob McElhenney, Marti Noxon, the Russo Bros., and Josh Singer.

He helped package many of WME’s biggest hit series, including This Is Us, Westworld, Sharp Objects, Jack Ryan, Chilling Adventures of Sabrina, and Riverdale. During his 23 years at WME, he has packaged dozens of series, including It’s Always Sunny in Philadelphia, Bob’s Burgers, The OC, Supernatural, and many series from the DC universe including Arrow and Flash.

He has become a larger influence on the feature side as well.

Endeavor President Mark Shapiro issued this internal memo:

“Over the past few years, Ari has taken on a host of new responsibilities and played an integral role in shaping the vision for the future of the agency. He is a deal maker without peer, cares deeply about his colleagues, and knows the industry inside and out…As we move into this next chapter, Ari is uniquely positioned to bring WME to new heights. He comes from television, but his curiosity and commitment to our leading role in the entertainment industry are extraordinary.”
