The software development company Distyl AI, a provider of operating systems for large enterprises specialising in Artificial Intelligence, is doubling its presence in Manhattan. According to Koeppel Rosen, the building manager, the company has leased the entire ninth floor at 135 Madison Avenue in Manhattan's NoMad district. This increases Distyl AI's total footprint in the building to 30,076 square feet.
Distyl AI moved into the Rosen family's 13-storey building in December 2025, as reported by Commercial Observer, initially leasing 15,038 square feet across the entire tenth floor. The asking rent for the latest expansion was $55 per square foot. Both leases run until January 2028, according to Crain’s New York Business, which first reported the leasing.
Max Koeppel of Koeppel Rosen represented the Rosen family in this transaction. Justin Pollner and Steven Rotter of Newmark negotiated on behalf of Distyl AI. Distyl AI's initial arrival at 135 Madison in December 2025 marked the opening of the company's first office in New York City and its second location overall, following the establishment of its headquarters in 2022 at 55 Hawthorne Street in San Francisco.
Successful expansion in New York
Max Koeppel commented on the development in a statement: “We are pleased to have worked with Distyl AI to reconfigure and expand the company’s presence across two contiguous floors at 135 Madison Avenue.” He also highlighted the company’s rapidly growing business, which necessitated the additional office space.
The office building at the corner of East 31st Street and Madison Avenue houses other notable tenants, including health technology platform Courier Health and co-working company WeWork. Further tenants include digital marketing firm Demand Growth Digital, e-commerce marketing company Mobikasa, and event space provider Blender Workspace. A spokesperson for Distyl AI was not immediately available for comment.
