Jovani Rampersad, the commercial leasing director for the Moinian Group, represented the owner while Deb van der Hayden and Noah Savage of Jones Lang LaSalle represented the tenant. Fusion, which is led by President Kevin Higgins, currently has 12 locations throughout northern and southern California and one other New York location, on Long Island. The Manhattan location on  Park Avenue between 30th and 31st Streets puts it within easy reach of the many tech companies that have flooded into Midtown South  in recent years.

Penn Station and Grand Central Terminal are also close, providing easy access to two of the city's biggest transportation hubs.

The company will take up an entire floor of the 12-story building.

In October, OfficeLinks, an office space and meeting facility provider, inked a deal for 14,000 square feet at 450-460 Park Avenue, a Class-A building owned by Moinian.

Other tenants include Merchant Cash and Capital, MPhasis Corporation and Mimeo.com.
