Incorruptible: Why Good Companies Go Bad... and How Great Companies Stay Great Hardcover – May 26, 2026

"Incorruptible by Eric Ries is the best and most important business book of the year." —Dan Heath, NYT Bestselling Author & Podcast Host of "What It's Like To Be..." From Eric Ries, creator of The Lean Startup, comes a bold and urgently needed rethink of how organizations are built—and why success itself so often turns companies against the people and principles that made them worth building in the first place.For decades, we've explained corporate corruption as a problem of bad actors, moral weakness, or isolated scandals. But that story doesn't match reality. Again and again, companies founded with strong ideals drift toward short-term thinking, extractive behavior, and mission abandonment—often despite the best intentions of the people inside them. Incorruptible argues that this failure is not primarily ethical. It is structural. As organizations grow, the systems that govern them—ownership, incentives, charters, accountability, and decision-making—quietly reshape behavior. When those systems are poorly designed, even principled leaders are pushed toward outcomes they never wanted. Success itself becomes a form of financial gravity, bending companies away from their original purpose. Drawing on two decades of work with founders, CEOs, investors, and institution builders, Ries shows how these failures arise predictably—and how they can be prevented. He reframes corporate governance not as bureaucracy or compliance, but as a creative and strategic act at the heart of building enduring, mission-controlled companies. At a moment when trust in business is eroding, Incorruptible offers a clear-eyed diagnosis and a practical blueprint for change. Success alone will not protect what matters most. Only incorruptible design can. Read more
