In Incorruptible: Why Good Companies Go Bad and How Great Companies Stay Great, Eric Ries argues that mission-driven companies face an invisible pressure that pushes them toward short-termism and conformity, no matter the intentions of their stakeholders.

Ries is the best-selling author of The Lean Startup, founder of the Long-Term Stock Exchange, and advisor to startups around the globe. In his new book, he traces a recurring pattern across two centuries of business: principled founders build something exceptional, only to watch it be corrupted—not by greedy individuals, but by systemic forces baked into how capitalism is structured.

In his conversation with Adam Job, senior director at the BCG Henderson Institute, Ries discusses how corporate corruption starts, why shareholder primacy became the norm, the concept of financial gravity, and the structural protections companies can put in place to defend their mission.
