Are they really cofounders if you are trying to structure it this way or are they just valuable employees? If you don't trust them now it will only get worse later when real money is on the line. That said, there are ways to structure it through stock classes like restricting the voting of their shares etc. Probably best to consult an attorney that is familiar with corporate structure and setup though. Also you can word the profit sharing agreement and even the AOI so that any changes to the profit share require all shareholders to agree not a simple majority. This protects you all from two people icing out the third.
