NEW YORK CITY-Bursting at the seams in their current space in the Chelsea Market, Innovatix, a division of the Greater New York Hospital Association, has sublet its 17,900 square feet there to advertising company Zenith Optimedia.

Jodi Roberts, a Cushman & Wakefield director who represented Innovatix in the sublease along with vice chairman Josh Kuriloff, says that growth made a move from the location at 75 Ninth Ave. necessary.

“They were doubling in space,” Roberts tells GlobeSt.com. “We decided that, since there was no more additional space available at Chelsea Market, to consolidate them with the Greater New York Hospital Association space at 555 W. 57th St. There was actually some vacancy there, which is rare for that building.”
