You need to see their track record. Have they published anything? Do they talk about their failures? How much actual business experience do they have? As someone who does both sides (software and business) I've come to realize that the best way to approach is as you would approach hiring a developer. You want someone who has shipped code and can ship code. Sometimes people exaggerate things, that's normal due to the competition. It is a red flag, but not a complete deal buster. Keep an eye for it. If it sounds fishy and does not have real data to back up then just send them out politely. By the way, I get way more red flags from hiring developers than from hiring business people. Dunno why.
