the.com/promoter

means Someone who organizes and publicly backs an event, venture, or cause — putting up the money, hype, and connections to make it actually happen.

from From Latin promovere, 'to move forward' — pro- ('forward') plus movere ('to move'). The word entered English in the 1300s–1400s meaning someone who advances or furthers something, and by the 1800s had narrowed in business and sports slang to the person who moves a fight, a show, or a company from idea to reality, usually by moving money and crowds along with it.
