Quadrangle Group

firm focused on growth capital investments in middle market companies across a range of industries. The firm invests primarily in businesses involved in media and communications sectors.
The firm, which is based in New York City, was founded in 2000 by Steven Rattner, former deputy CEO of Lazard Freres, with Joshua Steiner, Peter Ezersky and David Tanner.The firm has raised approximately $6 billion since inception and employs approximately 40 investment professionals in offices in New York, London, Palo Alto and Hong Kong. Quadrangle's private equity business raised a $1.1 billion fund in 2000, followed by a $1.8 billion fund in 2005. As of the end of 2008, the firm was currently raising a $2.25 billion fund.
In January, 2008, it was reported that New York Mayor Michael Bloomberg's extensive business interests were placed in "a sort of blind trust" with Quadrangle because of Bloomberg's possible run for the presidency.Bloomberg would "continue to have control of and access to certain investment decisions." On February 23, 2009, Rattner was named as lead auto industry adviser to Treasury Department Secretary Timothy Geitner, leaving Quadrangle. The report said Quadrangle would continue with its responsibilities for Bloomberg after Rattner's departure, and that Michael Huber, who joined the firm in 2000, and Steiner would become co-presidents of the firm.
