Reinventing the Leader

How to Change Yourself to Change Your Company

De: Guilherme Loureiro, Carlos E. Marin

Narrado por: Thom Rivera

An inspiring, practical book by Gui Loureiro, Regional CEO overseeing Walmex, Walmart Canada, and Walmart Chile, and his executive leadership coach Carlos Marin that shows how even the most successful leaders must be open to personal change in order to transform their company.

In the midst of a successful year, visionary CEO Gui Loureiro decided that Walmex—Walmart’s biggest division outside of the United States—needed to make massive changes to make the iconic company a more data-driven, customer-centric business that would be competitive in our digital economy. The stakes were high: no company the size of Walmex had ever attempted a transformation at such a magnitude of scale.

Reinventing the Leader is the turbulent story of how it happened that’s especially relevant in this age of globalization. Gui learns from Carlos that to change the company he must first transform his own leadership style. Written from the dual perspectives of a CEO and his leadership coach, this candid book provides an insightful blueprint for any organization’s success. Readers will learn:

• The importance of connecting a transformation to a meaningful purpose
• How any change brings risk but the biggest risk is not to change
• The three crucial questions to ask team members to discern if they’re ready to contribute to a transformation
• The need to tell the story of how the business impacts customers and customers impact the business
• Why it’s necessary to listen attentively and embrace change independently of how successful you are.

Today’s leaders are expected to inspire by sharing a vision based on purpose, not just profits. Loureiro and Marin’s enlightening account of self-discovery and business reinvention defines a fresh new approach to leadership for the future.

More Than a Book — A Mirror for the Conscious Lead

Guilherme Loureiro’s Reinventing the Leader is one of the most honest, timely, and necessary contributions to leadership thinking that I’ve read in recent years. It’s not a book about tactics or trends — it’s a book about transformation. And that transformation begins, uncomfortably but powerfully, within ourselves.

As someone who operates in the world of finance, investments, and organizational growth, I’m used to thinking in terms of strategy, capital, and returns. But what Gui challenges us to consider is the quality of leadership that underpins all of those outcomes. He reminds us — with humility and clarity — that leadership today is not about control, charisma, or performance. It’s about presence, purpose, and systemic awareness.

One of the book’s central ideas — “The best leaders are more present and less performative” — stayed with me long after I finished reading. It calls us to move from the illusion of leadership as visibility, to the practice of leadership as service.

Through stories, frameworks, and lived experiences, Gui invites leaders to reflect not just on what they do, but on who they are. In doing so, he offers a model of leadership fit for a world that is complex, unpredictable, and profoundly human.

This is not a book to read quickly. It’s one to sit with, return to, and use as a mirror. I recommend Reinventing the Leader to anyone in a position of influence — not just CEOs or founders, but anyone building cultures, guiding teams, or shaping futures.

Gui has given us not just a leadership book, but a leadership compass.

Very good lessons to practice

Exceptional story of transformation. A must read book for leaders looking for positive transformation in the new digital era.
