Synthesia, an AI video platform for business, has signed a 50,000-square-foot lease at GFP Real Estate’s 675 Avenue of the Americas for its new U.S. headquarters. The company has relocated from 245 Fifth Avenue, where it previously occupied approximately 13,000 square feet.
Dennis Someck and Justin Myers of Lee & Associates NYC represented Synthesia in the transaction. Jeffrey Gural and Alphie Toro of GFP Real Estate, along with Anthony Sciacca and Scott Gutnick of Newmark, represented the landlord, GFP Real Estate.
The lease represents a nearly fourfold expansion of Synthesia’s New York City footprint and is part of a broader U.S. growth strategy. The company has more than 250 employees in the U.S., including approximately 140 in New York, and plans to add more U.S. roles by the end of 2026.
Synthesia’s new offices will be designed to enhance both the employee and customer experience, with meeting and collaboration areas, flexible event space and a studio where customers can create custom avatars, conduct proof-of-concept work and collaborate on video programs. The building also features a shared roof deck amenity.
Built in 1901 as the Adams Dry Goods department store, 675 Avenue of the Americas spans a full city block between West 21st and West 22nd Streets. The property offers expansive 50,000-square-foot floor plates, 13-foot exposed ceilings, oversized operable windows, a 24/7 attended lobby, tenant rooftop amenity space and fully modernized elevator, mechanical and HVAC systems.
