They gave you everything you asked for. I don't see a reason for you to be miffed, unless it is at yourself. If someone else managed to negotiate a better deal, that's not a transaction that you were involved in or should concern yourself with. Perhaps the the founder is complaining about the guy because he isn't receiving the value from the sales guy that he feels he should based on what it cost him. If so, that will sort itself out, eventually. I'd ask myself this question, "Would I be happy with the deal I have if I didn't know about the deal the sales guy has"? If the answer is yes, then just stay where you are and work to make good things happen.
