I don't think so. The funny thing is that most people who grew companies to such level of success did so without a coach, but now that the hard part is decidedly over, a coach has become indispensable.
I can’t comment on your last post because it was flagged but I wanted to at least reach out to you with this:
Some of the best coaching I received was from people that may have been deemed less successful, powerful or intelligent than I am but because they took the time to know me and saw my blind spots, they guided me to amazing insights. It was about a connection and relationship. I am forever thankful for their commitment to me. Many of these coaches are selflessly giving to others after having received coaching themselves, so my experience with coaching is different than you seem to imply.
Lastly, I hope you don’t harbor a belief that all success is based on the dark side of human nature; that all CEOs and leaders merely exploit others. That is clearly disproven from so many examples of amazing leaders. Honestly that sounds like a bitter, resentful existence that will make it hard to collaborate with others.
The person to have the idea is not the one ideally fit to execute it, the person to execute the idea is not one ideally fit to run the company. But one can learn. If one was good enough at the previous step there is some wiggle room.
I also hear that people who at one time used a coach of some kind are helped by doing it again.
BTW, I also wonder if even the coaches see themselves for what they are. In which case it's disturbing to think that that someone can spend years meditating in an ashram in India and come out still knowing so little about themselves that they don't understand their dark motives.
