RXR is a privately held real estate investment and development firm headquartered in Uniondale and New York City. Founded in 2007 by Scott Rechler following SL Green Realty's 2006 acquisition of Reckson Associates Realty, where Rechler served as Chairman and CEO, RXR has grown into an integrated platform managing a diversified portfolio across office, residential, industrial, and public-private partnership sectors. The firm operates across multiple asset classes with a focus on Class A office properties, value-add multifamily residential developments, real estate credit through its capital solutions division, and large-scale public-private partnerships. RXR's investment approach centers on acquiring well-located but dislocated Class A office assets and developing rental housing assets nationwide. The company has established a presence in key growth markets including the New York City metro area, which accounts for the majority of its holdings, with additional investments across Pennsylvania, New Jersey, Connecticut, Arizona, Florida, North Carolina, Colorado, Texas, and South Carolina. In August 2025, RXR closed on its acquisition of 590 Madison Avenue for $1.08 billion, marking the largest full-asset, non-user driven office acquisition in New York City since March 2018. The firm manages 108 properties totaling 30.9 million square feet with $16.4 billion in gross asset value under management and employs 450 people.
