One of the big trends these days is for agents to set up teams. There are different versions of this but basically one agent is the team leader and they have other agents working with them. The team leader takes a portion of the commission from the sub agents. Another method is for agents to have teams but not actually promote themselves that way but they may have dozens of agents working under them and report all deals through the main agent.
People ask me how one agent can promote themselves as selling zillions of homes every year when in fact there are many other agents doing the actual ground work.
I have a few problems with these methods. Firstly, why are agents willing to share their commission with a team leader? Could it be they don't have the skills to work on their own? Secondly, if the main agent has so many sub agents working for them, there's a very good chance you'll never even meet these "super agents".
Do your homework before engaging these "TEAMS" because the person who impressed you at the listing time, may never be seen again.
