This is interesting. The folks over at UnBlinking have been using the Web (online phone books, Google cache, &c.) to track down information about the companies that had offices in the World Trade Center. They've come up with a more complete list than any of the mainstream media outlets. It's a bit sobering to scroll through the entire list and realize that entire companies, along with many people working at those companies, are completely gone.
