It depends on his skills. You say "building presentations, and managing teams", those are not really skills a startup needs (ie. they wouldn't hire someone just for those). I get the feeling his quantitative analysis skills won't suffice either. I would make a better list of skills that those startups may need, as in "I could help Banksimple do X or Y". Something very practical. Once he has those, get in touch with them and talk to them. Like, really, what could he have helped, say, Mint with, practically? It's just that consulting and stuff isn't really a good preparation for the startup world; consulting is not truly (often) about getting things done, startups are.
