Referring to Keirsey, ESTPs belong to the Artisan temperament and are called "Promoters".

Myers-Briggs Characteristics
According to Keirsey, ESTPs, or "Promoter Artisans", are the most adept among the types at manipulating other people. The ESTP knows everyone who matters and everything there is to do. They like to indulge themselves in the finer things in life and to bring other people with them. Their goal in life is to sell themselves and their ideas to others. Dramatic and debonair, they are gifted at earning others' confidence.
