Go out with the person on a personal basis. Get to know them ( only so that what you will eventually say will have more impact ), and then hit them with the following,

"Your anger and blaming doesn't work. It's actually giving away your power to others by pretending they are responsible for what is not working with your company. It looks more and it is more powerful if you own all of this mess, and take responsibility for all of it. Also, the anger stuff is unnecessary, it just makes you look frustrated and weak, because you seem to be saying you are so dependent on these other people that their choices so greatly vex you. Well...what kind of powerful person would do that? Look, I may not be the kind of entrepreneur you are, nor have the same technical or social skills. And I do know what I am talking about. Sure you can choose to believe that I'm just some person who doesn't have a clue what they are talking about, or you can choose to believe I know it when I see it. And believe me, I see it with you. I see your potential, and I see how these things are in your way. I want this company to be great, and I want you to be great. I know you are, there's just your lack of clarity on these issues which is missing."
