What does Martha have in common with Madonna, DeNiro, and Lil Nas X? Answer: Allen Grubman. In 1987 Martha was a caterer, new author, and just starting to branch out into retail. Grubman was a New York City lawyer, handling contracts for musical artists, who recognized the business potential. He helped negotiate Martha’s contract with Kmart, which they then leveraged to buy her magazine from Time-Warner ­­-- the most important deal of her career. Thirty-six years later, they are still working together, and Grubman is still creating power deals for the most influential stars in music, movies, and beyond. Listen here as they catch up.
