The Curve is a new way of doing business and of seeing the world.

For most of the last century, companies strived to sell more and more products at uniform prices. But the future of business is about variation: tailoring products for customers of all stripes, and letting your biggest fans spend as much as they like on things they value.

The Curve shows us not to be afraid of giving some things away for free. The internet helps you forge direct relationships with a vast global audience, and take them on a journey from freeloaders into superfans. Value lies in how you make people feel, by building communities, bespoke products and experiences. Small numbers of high spenders are enough to fuel a profitable business.

In games, free is becoming the norm, but some people now spend hundreds or thousands of dollars playing a single game. You can already see the Curve transforming areas like music, books and film, and it will rapidly spread to the physical world as 3D printing becomings reality.
