Legora, a company that developed a collaborative artificial intelligence-driven workspace for the legal profession, has signed a new 10-year lease for 98,420 square feet at SL Green Realty’s 11 Madison Avenue. This brings the building to 100 percent occupancy.
The deal brings a new office for Sweden-based Legora, which opened its New York City headquarters in 27,238 square feet at 838 Broadway last year.
SL Green was represented by Brian Waterman, Brent Ozarowski, and Erik Harris at Newmark. Legora was represented by Justin Haber and Kyle Riker at JLL.
The asking rent was unclear, but the office asking rent at 11 Madison Avenue was $90 per square foot as recently as March.
Legora’s lease brings the total square footage of office leases for SL Green, Manhattan’s largest office landlord, to roughly 1.5 million square feet so far in 2026.
