ICM Partners has acquired the Sagalyn Agency, a Washington, D.C.–based literary agency, following a four-year partnership between the two firms.

The move, announced by ICM publishing division co-heads Esther Newberg and Sloan Harris, follows the acquisitions of Headline Media News and the Royce Carlton Agency made by ICM in 2017, adding an office in the nation's capital to complement the firm's Los Angeles, New York, and London offices.

“The acquisition of The Sagalyn Agency gives us an important presence in Washington, D.C., at a time when the world’s eyes are on the city moment by moment and the opportunities in publishing are boundless,” Newberg and Harris said in a joint statement. “Strategic value and culture are our primary concerns as we continue to carefully grow ICM Partners, and in the Sagalyn Agency, much like Headline Media and Royce Carlton, we share a successful and productive, long-term, working relationship that has greatly benefited our clients.”

The Sagalyn Agency represents a wide array of journalists, historians, biographers, scientists, public thinkers, and novelists including Rick Atkinson, Susan Glasser, Michael Dobbs, Fred Kaplan, Dan Pink, Franklin Foer, and Robert Reich. Raphael Sagalyn, principle of the Sagalyn Agency, will immediately become a partner at ICM Partners.

“We are proud to join ICM Partners and their world-class literary division,” said Sagalyn said in a statment. “Our clients and staff will benefit enormously from the full range of services provided by the agents and staff throughout the firm.”
