Well Jobs was the first that came to mind, but Google, Twitter, Dropbox, Spotify (I know, not Valley)... all have this identical cult like culture where the employees are fully indoctrinated and feel their execs are the best in the world.
Not to be rude, but this has been my universal experience in the tech industry for the past 20+ years.

It ranges from pretty upbeat to exceedingly negative, and it also seems to correlate with how the company performs financially. Which makes sense since these people have half a million dollars of RSUs on the line.
