Incorruptible

Why Good Companies Go Bad and How Great Companies Stay Great




A powerful call-to-action and practical guide for building mission-driven companies that are truly incorruptible

\"Indispensable!\" - Kim Scott, New York Times bestselling author of Radical Candor

\"The best and most important business book of the year.\" - Dan Heath, New York Times bestselling author of Reset

\"Ries shows us, with rigor and optimism, how to build organizations that are worthy of our trust.\" - Frances Frei, Harvard Business School

The most radical and powerful idea in business isn’t disruption… it’s integrity.

The Lean Startup transformed how a generation of entrepreneurs build products and sparked a global movement for smarter, faster innovation. Now Eric Ries takes the next step, asking a deeper question: how can we build companies that stay true to their mission once they succeed?

In Incorruptible, Ries reveals the hidden forces that cause even great organizations to drift from their values and shows how to design businesses that can withstand that pressure. Drawing on two decades of work with founders, CEOs, and investors around the world, he exposes the structural flaws that make modern companies vulnerable to short-term thinking and moral compromise. He then offers the blueprint for \"mission-locked\" organizations that can grow, prosper, and endure without losing their soul.

Drawing on wide ranging examples including Cadbury, John Lewis Partnership, Vanguard and Anthropic, Incorruptible uncovers the urgent need for purpose-driven leadership. It gives every builder—founder, executive, investor, or citizen—the tools to create enterprises that uplift rather than exploit. We all have a role to play in shaping a better future. This book is the place to start.

Scott Cook, cofounder, Intuit

As a mission-driven founder, this is the book I wish I’d had while building. Ries offers both a new vocabulary and concrete, hard-won examples for how to create real value without losing your soul at scale. He explains why mission and massive growth so often end up at odds—and, more importantly, how founders can be intentional about choosing a different path.

Leah Busque, founder of TaskRabbit

Eric Ries gives founders a playbook to help avoid the inevitable pitfalls and find your path to the business you set out to create.

Eric Ries makes a compelling case that governance is not an administrative afterthought but a creative act at the very heart of building enduring companies. Incorruptible explains why even visionary founders lose control of their companies—and it shows how intentional governance can enable builders to achieve escape velocity.

Scott Stern, David Sarnoff Professor of Management at the MIT Sloan School of Management

If you want the world to be a better place than it is, this book is a good place to start.

Tim O’Reilly, Founder and CEO, O’Reilly Media

If you want to build a company that will be making the world a better place a hundred years from now, it’s not enough to be a great person with good intentions–you need to consciously build incorruptible governance. Ries shows you how. Indispensable!

Kim Scott, bestselling author of 'Radical Candor'

I've read countless business books, but this is the first that had me in tears not out of sadness, but because it gave me hope.... Incorruptible is not just a book. It's permission. It's a blueprint. And it's proof that you're not crazy for wanting to build something that's both wildly successful and deeply good, something that lasts. For any founder who truly wants to make a difference, this is a must read."

Vlada Bortnik, founder and CEO of Marco Polo

The best and most important business book of the year.

Dan Heath, New York Times bestselling author of Reset

This profound book will inform and infuriate, and then it will help you see a path forward. It should be required reading for anyone who manages (or has a manager). Gravity is real.
