Honest question: is there a situation in which you can identify a deficiency in your selling ability (as a founder) that subsequently makes sense to delegate to someone else?

Obviously, if your product doesn't sell, then your story isn't working. But what stories are out there where the founder didn't do the best job selling and someone came and crushed it as a chief member of the exec or early sales effort?

Forget big famous companies - what about the folks here?
