Who Are You as a Leader?

Claude Grunitzky is a world-class networker. He’s so good, in fact, that both Harvard Business School and Columbia Business School have published case studies about him. (I am a coauthor of the Columbia study.) Both case studies document how Grunitzky built and maintained professional relationships during the course of his career that allowed him to launch his first startup—a magazine called Trace, which covered hip-hop music—and subsequently a series of businesses, including an advertising agency and a media network that now operates in 190 countries.
