"But what I want to focus on is the power of a visionary leader to set out on bold ambitions and bring ideas to life." Apart from single-product companies I don't think this is really a thing. CEO's set the company culture, and maybe strategic direction (but it often doesn't need any kind of visionary genious to see which way the world is turning), and of course jump in on any 'big' deals or negotiations the company is dealing with, but are otherwise more curators than creators. IMHO.
