Abstract
In this compelling book, strategy guru Roger L. Martin and Skoll Foundation President and CEO Sally R. Osberg describe how social entrepreneurs target systems that exist in a stable but unjust equilibrium and transform them into entirely new, superior, and sustainable equilibria. All of these leaders-call them disrupters, visionaries, or changemakers-develop, build, and scale their solutions in ways that bring about the truly revolutionary change that makes the world a fairer and better place.
