Founders reach for a second adviser because they are thinking about capacity. The constraint is usually somewhere else entirely.
The reasoning goes: I am at capacity, so I need someone who does what I do.
But look at where the hours actually go. For most principals a large share is operational, administrative, and the coordination work between systems. A second adviser does not take any of that. They add to it.
Usually an operations or client service person. They absorb onboarding, paperwork, scheduling, the follow-up after meetings, and the reconciliation nobody enjoys.
That converts directly into capacity, and it does so in weeks rather than the year it takes to integrate an adviser.
A second adviser is a bet on growth that has not happened yet, usually with a compensation structure that assumes it will. An operations hire pays back against work already in the building.
Hire to remove hours before you hire to add revenue. The second one only works if the first has happened.
Hiring the person and then not giving them anything. Founders hand over the easy twenty percent and keep everything that requires judgement, which is everything that was taking the time.
Then they conclude that hiring did not help. It did not, because it did not happen.
Before the hire, list the specific tasks that will transfer and what "done" looks like for each. If you cannot write the list, you are not ready to hire — you are hoping someone will work out what you do.
When you genuinely cannot serve the clients you have, when there is a succession reason, or when a specialisation you do not have keeps coming up.
Those are real reasons. Feeling busy is not, by itself, one of them.
