You should enlist a friend or a mentor to help you prepare with this situation. They can come up with tough questions that the board might ask you and make sure that you have a coherent, clear answer. That has helped me tremendously in clarifying my own thoughts.

You should also roleplay with this person as if he is your cofounder. Have him be a dick and make any argument you can see you cofounder make at any point. I've learned that winning arguments and being right are two different things. This way, if your cofounder is good with the former, you need to be prepared and roleplaying will give you a great edge!

Also, write down all possible scenarios. So if the board asks you "what will happen if the employees quit?" you need to have already thought through that use-case. They will probably be very impressed if you have a document that has these use-cases and possible plans.
