When
Ion Storm existed, its corporate headquarters were in Suite 5400, of space in a penthouse suite on the 54th floor, the top floor, of the tower. Lisa Chadderdon of
Fast Company said that the penthouse location was "unusual". For the first ten years after the construction of the JPMorgan Chase Tower, the penthouse location had been unleased. The company Autonomy etalk planned to move its employees to the Chase Tower from
Las Colinas,
Irving in 2008.
Deloitte has an office in the tower which had 950 employees in late 2009. In early 2009, Deloitte announced that it planned to consolidate its Downtown operations and its operations in
Irving, Texas. Initially, there would have been a multimillion-dollar advantage to Deloitte if it moved to Irving. The City of Dallas proposed an economic grant to Deloitte if it decided to stay in Downtown Dallas. == In popular culture ==
