A team lead when one person can hold the team number, coaching, recruiting and the weekly rhythm. If you are deciding between a coach and a sales manager, the comparison is on the coach vs sales manager page before you replace them.
An operating partner when the leaks are in several places at once: lead conversion, recruiting, retention, a new market, and nobody owns the total number. The fractional COO for real estate page covers scope and cost.
Nobody yet if the team is missing its number for a reason that has nothing to do with leadership. Run the Funnel Check first, and check whether each agent has more leads than they can work .
