One World Trade Center has snared another full-floor tenant — Celonis, a major software firm that uses AI-enhanced processes to “transform data into insight and action.”

Celonis is taking the entire 34,328-square-foot 87th floor in the tower owned by the Port Authority and the Durst Organization. The asking rent was $85 per square foot. The deal brings the super-tall skyscraper to more than 85 percent leased.

Celonis is moving its US headquarters from 119 W. 40th St. The tenant was repped by a JLL team, while the landlord was repped by a Newmark Knight Frank team as well as Durst’s Eric Engelhardt and Karen Kuznick in-house.
