Synthesia, a London-based AI video platform, has leased ~50,000 square feet at 675 Avenue of the Americas in the Flatiron District, marking a significant expansion of its NY office footprint as it continues to scale. The lease lines up with an aggressive hiring push and a strategy to cluster in-office teams in product, sales and customer success, underscoring how AI and tech firms are seeking large, collaborative floor plates in prime submarkets like the Flatiron District.
The deal spans approximately 50,000 square feet and part of Synthesia’s plans to add more than 400 employees in over the course of the year. Synthesia previously took about 13,600 square feet at 245 Fifth Avenue in 2025.
