EliseAI Quadruples Headquarters Space in Relocation to Tiffany Building

For the second time in three years, EliseAI is upsizing its office footprint as it relocates its headquarters. The artificial intelligence startup focused on the healthcare and housing industries has leased 109,000 square feet at Chetrit Organization’s 401 Fifth Ave. for its New York headquarters.

The move to the former Tiffany & Co. Building in Midtown Manhattan will see EliseAI relocate from a 27,000-square-foot space at 33 E. 33rd St. it has occupied since 2023. The current space is itself an expansion of its original footprint at 33 E. 33rd.

“We are very pleased to welcome this prominent tenant to multiple floors of our Fifth Avenue property,” said Juda Chetrit and Michael Chetrit of The Chetrit Organization. “Their presence brings new energy to the corridor and underscores the continued transformation of the area, particularly as it emerges as a hub for innovative, AI-driven companies. With neighbors like Amazon, Fifth Avenue is clearly entering an exciting new chapter.”

EliseAI was represented by Evan Margolin, Valentin Stobetsky, Calum Waddell, Will McGarry and Hale King from JLL. Chetrit Organization was represented by Brian Waterman, David Waterman and Alex Kesseler from Newmark, who serve as leasing agents for the property.
