Nicole Diaz is the Global Head of Integrity & Compliance Legal for Snap Inc., where her responsibilities include promoting ethical business standards and adherence to the Code of Conduct, managing risk in key areas such as anti-bribery and trade law, and leading internal investigations. In this conversation with Stanford professor Tom Byers, Diaz insists that ethics is a strategic imperative for 21st century businesses, and explores how the concept of “enlightened self-interest” can create a framework for better decision-making without requiring a commitment to pure (and unrealistic) altruism.
