"Reading it made me so hopeful and excited that I've been telling everyone I know about it. This is not just a book for MBAs or people who work in business. It's for anyone who has wondered, 'Is capitalism fixable?'...The book doesn't encourage a pivot away from profit-making. Quite the contrary—it argues that if you want your business to do well, founders and executives should focus on doing good."

– Ari Shapiro, award-winning journalist and news anchor, and bestselling author

"Every founder hopes their path is a straight line. It won't be. They hope they will have the right mentor to help them avoid problems. They won't. 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, Entrepreneur and Investor

– Reid Hoffman, Co-Founder of LinkedIn and Bestselling Author of Superagency: What Could Possibly Go Right with Our AI Future

"Better is possible, but only if we understand what we're up against. 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."

– Seth Godin, Bestselling Author and Entrepreneur

"Incorruptible demonstrates the importance of mission-driven leadership and defying the status quo to build organizations that withstand the test of time. Through Eric's decades of experience building and running businesses, he articulates how companies avoid the traps of corruption and lead with values to thrive as organizations and reshape industries."

"After authoring the most important business book of the 2010s, Eric Ries has done it again. No business book became standard practice more quickly than Eric’s first book. Before my daughter started at her first software engineering job, the company told her to read just one thing: Eric’s The Lean Startup.

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. Eric unveils the unspoken truths on how to build a legendary success…and keep it successful.
When will it be seen as founder malpractice to not have read this book?"

– Scott Cook, cofounder, Intuit

“Incorruptible is Eric Ries at his most ambitious and original. He argues that corruption — extracting value from successful companies — results not from moral failure but from flaws in our institutions. Ries shows how organizations can be engineered to resist these flaws. This is a practical manifesto for building mission-driven companies that survive success without killing the golden goose.”

– Thomas R. Eisenmann, Howard H. Stevenson Professor of Business Administration, Peter O. Crisp Faculty Chair, Harvard Innovation Labs, Co-Unit Head, Entrepreneurial Management

"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
