Michael Kives, a longtime leader at the Creative Artists Agency (CAA), former aide to President Bill Clinton, and close advisor to investor Warren Buffett, is launching his new venture, an advisory firm called K5 Global where he will serve as CEO.

Kives has long been a link between the worlds of DC politicos and Hollywood stars. In a statement from Kives, K5 Global will “work with corporations, government entities, and start-ups, and will be involved in a range of industries, including sports, technology, politics, and entertainment.”

Kives is a longtime colleague of Bill and Hillary Clinton, working as interim spokesperson for the Clinton White House and serving alongside Huma Abedin in Hillary Clinton’s Washington office. During his tenure at CAA, Kives’ clients included Warren Buffett, Bruce Willis, Katy Perry Jesse Eisenberg, Eric Stonestreet, and Jessica Alba.

Warren Buffett said of Kives, “I have known Michael for 10 years and he is one of the most creative and well-connected professionals in his space. Michael knows the worlds of finance, media, technology and popular culture and has an unusual understanding of how those industries will intersect and develop in the future.”

Richard Lovett, president of CAA, said of Kives’ departure, “Michael Kives is an absolute original. Because of his incredible instincts and unique ability to connect people, he has created a vast network that will help to provide growth and opportunity for anyone fortunate enough to work with him.”
