With her longstanding Wall Street career (Citigroup, Merrill Lynch) and unique perspective as a woman in a predominantly male industry, Sallie Krawcheck is tackling a question that has mystified investment banks for decades: how to successfully market wealth management services to women. As CEO of digital financial investment platform Ellevest, she sees diversity as the greatest advantage in cracking the code. Krawcheck encourages each employee to bring their "whole self" to work, and emphasizes hiring the best fit for the team, which in some cases could be a different choice than the person who traditionally would be considered the best fit for the role.
