I have a friend that is an Oracle DB Architect. One day he tells me he's left the bank and is working for some Swedish multinational. Tells me the name and I go "hmm, never heard of them". Website is a simple one page affair with contact information (in 50 countries) and nothing else.
I tell another friend about this company, he's a family investment planner (the guy that rich people give money to when they are too rich to work). He tells me in the hierarchy of multinationals, this one is at or near the top. You never hear about them because 99% of everything you buy is financed through them.
And that is Oracle's main clients. Really large companies with incredibly deep pockets and, most likely, a simple webpage that doesn't describe what they really do.
Think of it, most people never heard of AIG, until the government had to loan them $182 billion.
