You don't understand how press coverage works. Being upper-class has nothing to do with it, unless you are princess diana. You just pay people to do your PR. They get the story into the press for you. The PR people themselves are NEVER from upper-class backgrounds... it's a pretty ghetto occupation to get into in the first place. In fact they are usually from such limited backgrounds in the first place that half of them will do the work for almost nothing. (but it's the ones who charge a lot who you really want to hire)
You know nothing about the upper class. They don't need to hire PR firms (which is very expensive and unaffordable to a bootstrapped startup). They have their well-connected daddies and uncles make phone calls to get press coverage, etc.
