“As a company that focuses on location, our company headquarters is especially important to xAd,” says Dipanshu Sharma, CEO of xAd. “xAd has doubled in size over the past two years and will more than double yet again in 2015. With our rapid expansion, we need a headquarters that allows us to sustain our momentum. Our move to One World Trade Center will raise xAd's profile as an emerging leader at the intersection of New York City's media, advertising and technology community.”

To encourage xAd's headquarters expansion in Manhattan, Empire State Development has offered the company $3.4 million in performance-based Excelsior Jobs Program Tax Credits, which are tied directly to the creation and retention of up to 350 new jobs, as well as the retention of 76 existing jobs, over a 10-year period. Before deciding to move forward with the expansion in New York, xAd, which has offices in California, Illinois, London, China and India, considered moving to New Jersey.

International publishing giant Condé Nast, which began occupancy earlier this month, is the property's anchor tenant. It is taking nearly 1.2 million square feet between the 20th and 44th floors to serve as the company's global headquarters. In late August, it was reported that Servcorp had signed a 15-year, 34,775-square-foot lease on the 85th floor of the 1,776-foot-tall tower building.
