Well let me put it this way... If there are any really good young host that work out of there room, you probably wont ever know because they are smart enough to make it look like they are operating a great hosting company. Customers care about one thing... SATISFACTION. Are they getting there moneys worth, are they kept happy. If your doing that, I don't think they will question you very much or even care where it's being ran from. I know some of the "bigger" host companies owners who started out young and look at them now. I'm not going to say who because I wouldnt want someone to judge them on there age, I want them to judge them on there service.
