Multi-sided platform

Some businesses serve not one kind of customer but several at once, and their genius lies in balancing groups whose interests both align and conflict. That is the multi-sided platform.

A multi-sided platform is an intermediary that creates value by serving several distinct, interdependent groups of customers, enabling interactions between them that benefit all sides. Payment systems serving cardholders and merchants, marketplaces serving buyers and sellers, operating systems serving users and developers, all are multi-sided platforms whose value lies in connecting the groups they bring together.

Serving several sides at once

Unlike a conventional business with one kind of customer, a multi-sided platform must attract and serve multiple groups whose participation depends on each other. Each side values the platform more the more participants there are on the other sides, the cross-side network effects that drive platform economics. The platform's task is to get all the necessary sides on board and to keep them in balance, since a platform strong on one side but weak on another fails to deliver the interactions that make it valuable. Managing several interdependent groups at once, rather than one, is what distinguishes the multi-sided platform.

The art of pricing the sides

A distinctive feature of multi-sided platforms is the way they price their different sides, often charging one side heavily, another lightly, and sometimes subsidising a third. Because the sides are interdependent, the platform optimises across them as a whole rather than pricing each to cover its own cost. It may give one side a free or subsidised offering to attract the participants that the paying side values, recouping from the side more willing or able to pay. Judging a multi-sided platform by whether each side individually covers its cost misreads it, since the economics work only across the sides together.

Growing and balancing

The central challenge of a multi-sided platform is reaching critical mass on all sides at once, the chicken-and-egg problem, since each side hesitates to join until the others are present. Platforms solve this through subsidies, by attracting one side first, by seeding the other side, or by clever sequencing. Once critical mass is reached, network effects make the platform increasingly valuable and hard to challenge, but the balance among the sides must be continually managed, since neglecting any necessary side can unravel the whole. The platform succeeds only as long as every side it needs continues to participate.

The multi-sided platform is the business form that creates value by serving several interdependent groups at once, balancing their interests and harnessing the cross-side network effects that bind them together. Its distinctive economics, of pricing the sides as a whole rather than individually and of solving the chicken-and-egg problem of attracting them all, make it both powerful and difficult, since the platform that masters the delicate art of serving and balancing multiple sides can build a position of great value, while one that fails to ignite or balance them never gets off the ground.
