"THE BEST AND MOST IMPORTANT BUSINESS BOOK OF THE YEAR." - Dan Heath, New York Times bestselling author of Reset

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, offers the blueprint for "mission-locked" organizations that can grow, prosper, and endure without losing their soul.

Including wide-ranging examples such as 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.
