A must-read for any founder, board member, investor, or consumer who cares about protecting entrepreneurship, innovation, and the productive power of capitalism from the dangers of short-term thinking—and for anyone who recognizes the importance of trustworthy and enduring institutions for a thriving democracy.

After authoring the most important business book of the 2010s, Eric Ries has done it again.... If you’re a founder, a CEO planning an IPO, an investor seeking epic outcomes — stop now and read Eric’s book. It will change your life.
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.
Mark Cuban
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.
