Ben Horowitz, a leading venture capitalist, modern management expert, and New York Times bestselling author, combines lessons both from history and from modern organizational practice with practical and often surprising advice to help executives build cultures that can weather both good and bad times.

Ben Horowitz has long been fascinated by history, and particularly by how people behave differently than you’d expect. The time and circumstances in which they were raised often shapes them—yet a few leaders have managed to shape their times. In What You Do Is Who You Are, he turns his attention to a question crucial to every organization: how do you create and sustain the culture you want?

To Horowitz, culture is how a company makes decisions. It is the set of assumptions employees use to resolve everyday problems: should I stay at the Red Roof Inn, or the Four Seasons? Should we discuss the color of this product for five minutes or thirty hours? If culture is not purposeful, it will be an accident or a mistake.

What You Do Is Who You Are explains how to make your culture purposeful by spotlighting four models of leadership and culture-building—the leader of the only successful slave revolt, Haiti’s Toussaint Louverture; the Samurai, who ruled Japan for seven hundred years and shaped modern Japanese culture; Genghis Khan, who built the world’s largest empire; and Shaka Senghor, a man convicted of murder who ran the most formidable prison gang in the yard and ultimately transformed prison culture.

Horowitz connects these leadership examples to modern case-studies, including how Louverture’s cultural techniques were applied (or should have been) by Reed Hastings at Netflix, Travis Kalanick at Uber, and Hillary Clinton, and how Genghis Khan’s vision of cultural inclusiveness has parallels in the work of Don Thompson, the first African-American CEO of McDonalds, and of Maggie Wilderotter, the CEO who led Frontier Communications. Horowitz then offers guidance to help any company understand its own strategy and build a successful culture.

What You Do Is Who You Are is a journey through culture, from ancient to modern. Along the way, it answers a question fundamental to any organization: who are we? How do people talk about us when we’re not around? How do we treat our customers? Are we there for people in a pinch? Can we be trusted?

Who you are is not the values you list on the wall. It’s not what you say in company-wide meeting. It’s not your marketing campaign. It’s not even what you believe. Who you are is what you do. This book aims to help you do the things you need to become the kind of leader you want to be—and others want to follow.

Cet ouvrage retrace les difficultés rencontrées par Ben Horowitz au cours de sa carrière d’entrepreneur et de dirigeant.  Que faire quand on a fait une erreur et que tout va mal ? Comment prendre la bonne décision quand toutes les décisions sont mauvaises ?

A partir de  sa propre histoire (son enfance, ses débuts, sa première société) et de  ses expériences, il donne des conseils et des  leçons de vie, sans langue de bois (comment renvoyer ses employés ou comment  maîtriser ses propres démons). La qualité la plus importante d’un PDG  est, pour lui, la capacité à se concentrer pour prendre la moins mauvaise des décisions, quand il aurait plutôt envie de fuir ou de se cacher. Ses conseils sont souvent brutalement honnêtes, il critique le “délire de la positivité”,  il faut dire les choses telles qu’elles sont, car l’honnêteté engendre la confiance.
Il n’y a pas de recette miracle, ni d’ingrédient secret. Il faut garder en tête que, quand les choses vont mal, tout le monde se fiche de votre entreprise — médias,  investisseurs, conseil d’administration, employés. Ce n’est pas d’eux qu’il faut s’occuper  mais de vos collaborateurs, des produits  et des résultats financiers : si votre entreprise est un endroit où il fait bon travailler, vous aurez une chance de vous en sortir.
Enfin quand une entreprise grandit, elle rencontre des difficultés nouvelles : ce qui était facile peut devenir ardu, comme la communication, la structure de l’organisation, l’élaboration des process. Le défi consiste à grandir sans dégrader tout ce qui a fait la force de l’entreprise.
