What You Do Is Who You Are

What You Do Is Who You Are examines how leaders create and sustain organizational culture through historical case studies and modern business examples. Ben Horowitz analyzes four models of leadership and culture-building: the Haitian slave rebellion leader Toussaint L'Ouverture, the samurai warrior code, Genghis Khan's practices, and prison gang leader Shaka Senghor. The book connects these historical figures' methods to contemporary business challenges through Horowitz's experiences as a CEO and venture capitalist. Each section extracts practical lessons about establishing values, maintaining ethics, and transforming organizations through deliberate cultural decisions. Horowitz presents specific techniques for defining and implementing culture, from creating company-specific practices to addressing issues of inclusion and ethical behavior. The narrative moves between historical analysis and present-day applications in technology companies and startups. The work explores fundamental questions about authenticity in leadership and the relationship between stated values and actual behavior in organizations. It challenges conventional wisdom about corporate culture and presents a framework for leaders who aim to build lasting, ethical institutions.
