Either that, or just have one person who is the leader and who has override authority on everything. Team consensus is not really a way to build a company - in the end there will have to be one overriding vision.
A better setup is to have someone who makes the decisions for any particular area (on a notify-but-don't-ask-permission basis). Then the others can challenge if they really care, but won't for anything immaterial because they know they delegated those matters.
