MediaMath Inc. will be moving its headquarters downtown to 4 World Trade Center. The global technology firm has signed a 15-year lease with Silverstein Properties Inc. for 106,000 square feet.
Early next year, MediaMath will consolidate more than 300 employees at 4 WTC from three existing Midtown offices, totaling about 90,000 square feet, at 1440 Broadway, 1301 Avenue of the Americas and 535 Madison Ave. MediaMath will fill three floors, the 44th through 46th, at 4 WTC, a 72-story, high-tech, state-of-the art tower that opened in November 2013 at the 16-acre World Trade Center site.
