In fifteen seconds, I used my four rules for what I call warm calling: (1) Convey credibility by mentioning a familiar person or institution—in this case, John, Jeff, and WebMD. (2) State your value proposition: Jeff’s new product would help Serge sell his new products. (3) Impart urgency and convenience by being prepared to do whatever it takes whenever it takes to meet the other person on his or her own terms. (4) Be prepared to offer a compromise that secures a definite follow-up at a minimum.
