New York, NY – March 9, 2026 – Clay, an artificial intelligence-driven sales platform, has secured a 10-year lease for 163,095 square feet at 11 Madison Avenue in Midtown South, New York City.

About 11 Madison Avenue

Originally designed by Harvey Wiley Corbett and Dan Everett Wade in 1928 and completed in 1950, 11 Madison Avenue was initially conceived as a 100-story skyscraper. While the Great Depression limited its final height to 30 stories, the building’s base was constructed to support an additional 70 floors. It is considered one of the finest Art Deco structures in America.
