Big Four Consulting, then Top Tier Investment Bank => Warning Signs galore !!

Maybe your experience didn't cover being on the receiving end of these organisations doing a hard sell to win new business. If they were used car salesmen, you'd pay for a Lear jet (theirs) and end up owning a rust bucket, oil leaking Hyundai to drive to work.

My view is that this person is potentially going to be a business side of the venture, which means that selling oil leaking Hyundais to people around is a great skill to have.

on the other hand - get to know him more. meet in person - vet him out.
