Drawing from their own twelve-year partnership and from interviews with 125 women business partners across the world, Betsy Polk and Maggie Chotas have learned something powerful: when women work together, they discover a level of support, balance, confidence, and accountability and a freedom to be themselves that is rarely found in other work relationships. Heroic male partnerships are a staple business success story, but female partnerships rarely receive the same kind of attention. This work is a call for women to recognize and build on the inherent strengths that make them uniquely able to create successful trust-based professional relationships.
