Mastermind

A group of six to twelve people, a monthly or fortnightly call, a hot seat where one member brings a problem and the rest pull it apart, and often a retreat once or twice a year. Prices run from a few hundred a month into five figures a year, and the pitch is the room rather than the host.

That is also the risk. What you get depends almost entirely on who else paid, so ask who is currently in the group and what stage their businesses are at before handing over anything. Creators sell them because the margin is excellent and the delivery load is far lower than one-to-one coaching.
