NEW YORK CITY-Sapient Corp., a provider of marketing and technology services, has signed on to lease a 52,000-square-foot space at 40 Fulton St. in lower Manhattan. The lease is for a 10-year term and will allow Sapient to consolidate its two Midtown locations when it moves sometime this mid-summer or fall.

Prices weren’t disclosed, but according to data from CB Richard Ellis, average asking rent for the downtown market in which 40 Fulton sits were $39.33 per square foot for March 2011. The area has a vacancy rate of 8.9%.

Ron Lo Russo represented Vornado Realty Trust in-house in the deal. Studley’s William Montana, Ben Nottingham and Robert Richards of Boston’s Richards Barry Joyce & Partners represented Sapient. 40 Fulton St. is a Vornado Realty Trust building, as was the company’s previous home at One Penn Plaza, where it occupied space on two floors. It will increase its space by 31,000 square feet in the new location and expects to utilize the additional space when the move is complete, and is already looking at additional floors in the building, according to Hank Summy, senior vice president and New York managing director of SapientNitro.
