Before this interview, I might have said that Brad Hargreaves is an expert in starting companies--that is until he told me that his current startup, Common, is the first time he intentionally tried to start a big company.  So how does an entrepreneur who "accidentally" stumbled into General Assembly, the hugely impactful education business, wind up winning in businesses where he isn't the category expert going in?  He recruits help, obviously, but how can he figure out if the help knows more than he does or if it's right?  That's what we discussed in this enlightening episode.
