No Co-CEOs

Tell me who is in charge.  I want to know who’s head will roll if this thing goes south.  Don’t tell me that 2 or more of you are in charge, I want to know that if there’s a disagreement between the founders, that one person has the bigger voice.  They might have it because they invested more, that they went with less pay, or put more resources in.  But there has to be one person who can be pointed to for the success/failure of the venture.
