Most businesses start off with a founder selling their time and with the maximum earnable revenue being tightly limited by the founders available time. The founder works themselves into a stupor and at some point they go through what is often a difficult transition where they “step back” from the business and employ others to take over their various jobs. Many businesses don’t make this transition and it is the subject of much discussion in MBA programs world-wide. If you’re an I.T. consultant or lawyer selling your own time, you can’t scale.
