If your different companies have different IP addresses, then your
server can check the IP address which the client requested and
set the data root directory accordingly.   This is what most 
"virtual host" servers do.

If all the companies have the same IP address then you might have
your server check for the Host header.  Lots of clients supply it
(e.g. Netscape 2.X and 3.X).  If there is no Host header you could
send a default menu page asking the user to select which company
she wants.
