Oh yes it can! It is called the Investor Agreement. A 10% shareholder or less can control the company if the terms are in the agreement. Most agreements are not publicly available so it is difficult to know what is going on when you compare deals. Have you ever made an angel investment and then regreted that you did not have more control? VCs have. It is like who wins in the end, it all depends on the x of the VC investment. It is not what it says on the can, it is what's inside that matters.
