You're right, the article is sort of clumsy. There are three sparkplug issues at work here: 1) founder self-awareness 2) how to hire people and 3) how to develop effective teams. They're all lumped together in the article (and in many actual companies). What would have prevented the problem in the first place? Somehow short-circuiting the tendency, especially in founders, to insist the same qualities as your own are most useful in business building.
