Are you willing or can you share the names of some of these companies?
But I agree with the other responder, I've also been in many startups and have certainly seen tons of exaggerations about the future but never outright lies about the present that Holmes was guilty of. Even worse, if you're going to lie about the present, you should at least have strong confidence your lie is physically possible - Theranos tech was always a sham from day 1.
I just don't buy at all the "everyone in Silicon Valley does it" spiel, because if they did, investors of failed startups (i.e. the majority) would have tons of reasons to sue and put people in jail.
