I think you're dreaming with adding upper management. They couldn't keep a receptionist. I'm praying that he gets it to a certain point that it proves the product is good to go and has big companies lined up and then sell it to someone who knows how to be a CEO of a big company.
Kim doesn't want to bring on someone who might show him up. Also to proud to relinquish his position. He likes the one man show of whatever power he thinks he has. Kinda like Batman and boy Wonder.
