They may be three different names but they have a common link. For starters, they have a link with the cinema industry and the people involved are also quite interlinked to each other. Well, these are the names of the offices of some directors.
Company is the office of the eccentric genius Ram Gopal Varma which came up recently in Mumbai. Cave happens to be the office of speed director Puri Jagannadh which is in Hyderabad. This shot to headlines owing to its interiors which remind you of Europe.
Last but not the least, Karkhana happens to be the office of actor/director JD Chekravarthy. Incidentally, both Puri and JD are protégés of RGV and three of them are setting a new trend with such names to their offices. Both Company and Karkhana have an almost similar meaning though.
