The YC Demo Day is a private gathering. From descriptions I've read, it's essentially just the founders of the given batch and "accredited investors" (in US legal parlance, I believe "accredited investor" means having a net worth greater than 1 million or a yearly income in excess of 250K, but I'm not a lawyer so I might be wrong). On past Demo Days, at least there was one, trusted, member of the "press" from techcrunch at the event. One of the problems with Demo Day is not all of the companies are publicly announced when it happens and they want to keep working in "stealth mode" while raising capital. Said trusted person from the press is told which companies they can and can't write about. Though the world could probably learn a lot from videos of the pitches on Demo Day, I sincerely doubt they will ever be released to the public.
