Not sure I agree with that. While in theory, anybody could apply this advice equally well, there are certain types of people who are too far down the rabbit hole to properly process feedback. For us, it's definitely been very helpful to have a non-technical founder on board, someone who can push for problems to be solved even when they're inconvenient (or technically insignificant), because they don't code on a day-to-day basis. I suppose this is more a case for a "savvy product guy" than a "business guy" per se, although both refer to non-technical people.
