On this week’s podcast, hear Martha in a revealing conversation with one of her closest friends and teachers. Charlotte Beers broke the glass ceiling of the “Mad Men” advertising industry as the head of two global advertising agencies. She served as Under Secretary of State for Public Diplomacy and Public Affairs for Colin Powell. She and Martha met as divorcees, single women carving their paths in a demanding New York City business environment. Their friendship grew as they built brands, sharing ideas and learning from each other, and celebrating their successes together. Martha trusted Charlotte’s business expertise so much that she asked her to join her company’s board. Here, the two talk about pioneering the concept of brand stewardship, why women need to keep their own scorecards, and stories they usually share only with each other.
