This is so wrong is so many areas that I have not time to cover them. Lets just say is mot fair at all to whoever is risking the money, and not good for company growth and lasting. At the end you want the company to last otherwise you will find yourself looking for a new job, this model does not seem to allow for this.
I suggest Instead:
Create a cooperative. Let employees buy shares of the cooperative. Contrary to a corporation, on a cooperative you get only one vote independent of how many shares you have. And employees that have THEIR OWN MONEY, tied to the company would like that company to succeed. Instead of a CEO, subdivide the decisions on cabals. With the directive taken from one person from each cabal. And require that the person of each cabal change every year.
