Platforms and Power (with Hamilton Helmer and Chenyi Shi)

Hamilton Helmer describes Seven Powers as a way to make strategic pattern recognition more available to founders and operators. He separates two step changes in company value: finding product-market fit and building power. Product-market fit creates value, while power determines how much of that value the company can retain. He argues that both require invention, so the framework should help the people making strategic choices see more clearly what might work. Platforms complicate the analysis because they can involve different forms of power and are difficult to assess from the outside.

Chenyi Shi defines a platform broadly as an intermediary for transactions, rather than limiting the term to digital technology. Her historical example is a village matchmaker who kept information about single people and arranged introductions. The matchmaker performs the same basic role as modern platforms: connecting different sides and trying to improve the match. The example helps separate the platform business model from the technology used to operate it, while showing that a platform can exist even without software or the internet.

The guests say technology can lower search, information-entry, distribution, and other transaction costs enough to create markets that previously did not exist. Mobile devices make discovery and transactions easier: a user can find a counterpart, press a button, and pay without negotiating or entering payment details. The village matchmaker's notebook offers a simpler analogy—recording more people reduces the cost of remembering and matching them. Modern services such as Uber, Airbnb, and TikTok use newer technologies to reduce different kinds of friction.

Lower friction creates a paradox. The same technology that helps a platform reach product-market fit may also make it easier for competitors to enter or for users to multi-home. Rapid growth and large transaction volumes therefore do not, by themselves, establish power. A company can create substantial value while retaining little of it if rivals can reproduce the service and customers can move between platforms easily.
