Treeswift leases nearly 7,500 sf at 256 West 38th Street
The AI infrastructure firm signed a four-year lease at an asking $39 per square foot and plans to move into the space in August.
Philadelphia-based Treeswift, an artificial intelligence-driven infrastructure technology company, is expanding its New York City operations by leasing the entire 11th floor at 256 West 38th Street in Midtown, Commercial Observer reports.
The deal covers 7,487 square feet on a four-year term, with asking rent set at $39 per square foot, according to landlord broker Lee & Associates NYC. The firm will move into the new offices in August.
Lee & Associates broker Todd Korren said in a statement that AI companies have become among the most active drivers of office leasing demand in Manhattan, and that many are seeking efficient, well-connected headquarters rather than trophy towers.
Treeswift specializes in infrastructure inspections, vegetation management, construction planning, wildfire mitigation, and storm response. The article also notes the building’s ownership context, including a March 2025 acquisition of the property by Rex Hakimian and Empire Capital Holdings after Empire Capital acquired the building and nearby 229 West 36th Street out of distress for $50 million.
