Depends on how you want to be perceived. One of the most interesting article I read talked about how this founder carries 2 business cards. When he meets prospective clients, his title on the card says "VP of Sales" so his organization seems much bigger than a 1 man shop. But if he is meeting investors, he uses his CEO title card so he seems to be the one in control. I think this scenario would apply to you pretty well :)
