Most founders cannot explain why they don't employ advisors. I am not sure there is a rational explanation. It is just not part of their arsenal. Or, as Elena Verna put it, "Working with advisors is a superpower." My personal bias has been the friction of engaging with advisors due to lack of experience at scale. You just don't do it often enough to master it, like hiring. And yet, having a hungry team member coupled with an advisor who's been there and done that is possibly the most powerful setup.
