There's certainly no shortage of company founders who claim to have been unfairly ousted from the role of CEO of their own company by their investors. However, a transition in the role of the company founder does not have to end in tears, many entrepreneurs successfully manage a change in leadership, both for themselves and their businesses.
In my opinion only one of them truly understood early stage business and the leadership credentials it takes to run one. That was Cranfield. I am not saying that Stanford and LBS were not excellent schools but they were almost entirely run by academics and attended by academic business people too.
