Ownership
The founder is still the answer
If every question in the company still terminates at your desk, you do not have a team. You have a queue.
This is not a character flaw. It is often how the company survived. The cost is that growth now requires a different nervous system: yours, and the organisation's.
The coaching is not "delegate more." The coaching is: tell the truth about why you still need to be the answer, then rebuild the roles, the rhythm, and the conversations so the company can move when you are not in the room.
