Mostly crap, but I like pembient and maybe Clara foods, they have shots at making it. I really want an abiobot but I don't think their founder will make it. Same with arc reactor. Blue turtle was the fraudster of the group. I know enough about Gaucher disease to know that their proposal was total nonsense.

I'm not harshing on class 1 - probably even with ycombinator, many classes if not all are "mostly crap". Zero, though, is stunning.
