Definitely an odd question, however if you call the information office they could probably help you out.
It's a hard question. For example. The touristique tours to floor 103 might be one only business or perhaps it is divided into gift shop. Pictures. Restaurant. Entrance and access. Perhaps also security.. Anyhow I'm sure hundreds of offices very diversified. Big companies and lots ob subsidiaries
I was just there, and I saw 3 or 4 names, none of which I recognized, but those could've just been the "bigger" ones. Honestly, I don't know.
No clue
