I'm confused by your comment. Sure Apple, Microsoft, and Oracle are older established companies but from everything I know about Apple and Microsoft their stories seem very much to fit the startup mold (don't know much about Oracle). And the other three Zynga, Facebook, and Uber are comparatively much more recent successes that definitely took the standard seed funding to VC route and embody everything you would think of as a modern startup.
So you're saying that this doesn't apply to super successful startups? Honestly that's not been my experience, both personally and from plenty of stories I've heard from the more "modest" startups that have been successful but not on the same grandiose scale these companies have been.
