The Crossover Point is the moment at which solving a hard problem structurally becomes cheaper than leaving it unsolved. Across eleven fields, including global health, financial exclusion, education, legal access, energy, and climate adaptation, that crossing has already happened.

Problems affecting millions and, in some cases, billions of people are now cheaper to solve than to maintain. That makes hard problems the most significant commercial opportunity of this decade.

Capturing that opportunity relies on a different kind of leadership: people willing to build architectures that produce positive-sum outcomes in the fields where hard power, money and mandate, has failed.
