As someone who wrote internal software for a fortune 100, probably all of them. EDIT: When I first read your question, I thought you meant 'which companies?', now I realize you're asking who to talk to within a given corp. The answer to that probably boils down to 'whoever is getting bribed with kickbacks from enterprise software makers'

The people who set the requirements for my biggest project tried to massively expand them about 2 weeks before the end of the project, then tried to bury it after we instead focused on polishing UX and debugging for those 2 weeks. Several years later I hear it's still in use internally and the users refuse to migrate to a third party solution despite pressure from execs who probably want kickbacks.

Giant corps have no idea what the difference is between usability and number of features.
