Koeppel Rosen arranges 15,038 s/f Distyl AI lease expansion
Manhattan, NY Koeppel Rosen LLC arranged a 15,038 s/f lease expansion for Distyl AI, Inc. at 135 Madison Ave.
In 2025, Distyl signed a 15,038-s/f lease for the entire 10th floor at 135 Madison Ave. With this new lease, the company now occupies 30,076 s/f across the entire 9th and 10th floors at the building.

Backed by leading venture firms and founded by industry veterans, Distyl AI’s expansion reflects its continued growth and commitment to advancing enterprise innovation in the city.
“We were pleased to work with Distyl AI to reconfigure and expand its footprint across two contiguous floors at 135 Madison Avenue. We celebrate the company’s rapidly growing operations, which required additional office space,” said Max Koeppel, Director of Leasing at Koeppel Rosen.
