>You kind of need a "Yes-Man" if you're on early stage of startup inventing your own dream (I'm sure this is going to open a can of worm but hey... it's your startup).

Nonsense. You are not smart enough to run your company. That bears repeating: You are not smart enough to run your company.

In other words, you will face unexpected challenges and problems that you aren't smart enough to solve on your own. In a situation like this, being surrounded by "yes men" is the worst possible place to be. Employees that can't or won't think for themselves won't be able to help you get out of a jam. They won't be able to tell you that you're going in the wrong direction. Instead, your own workload will grow exponentially as you find yourself having to tell your employees what to do as opposed to having them figure it out for themselves.

Even worse, you'll find yourself cut off from vital information. You'll find that you don't receive news unless you specifically ask for it. In other words you'll be flying blind with faulty instruments. That's not a situation I'd like to find myself in as an entrepreneur. I would much rather have employees who can take initiative to fix problems and pounce on new business opportunities. I would much rather have employees who tell me that things are going badly without having to be prodded. A "yes-man" is the very antithesis of this.
