Platforms and Power (with Hamilton Helmer and Chenyi Shi)

We sit down once again with one of the world’s very best strategy thinkers, 7 Powers author Hamilton Helmer — this time joined by his impressive Strategy Capital colleague Chenyi Shi — to discuss platform businesses, and how the Power framework applies to them. If you’re building, investing in, or just curious about the dynamics of platforms, this episode is a must-listen. We owe a huge thanks to Hamilton and Chenyi for sharing their work-in-progress insights on this very special category of companies. Tune in! Also -- JOIN US FOR THE ACQUIRED ARENA SHOW!!

WHAT IT’S REALLY ABOUT

How to analyze platform power beyond product-market fit flywheels

The episode introduces an in-progress framework for diagnosing whether a platform can achieve durable power, distinct from merely achieving product-market fit and rapid growth.
Helmer and Shi define platforms broadly as intermediaries that facilitate transactions (not just digital), and argue technology’s key role is lowering transaction costs enough to create new markets.
They propose three core questions: (1) how value is created and how it scales, (2) how each participant segment perceives that value as the platform scales, and (3) what blocks competitors from achieving equivalent value (the “barrier” side of power).
Examples like Uber/Lyft, YouTube, Airbnb, and stock exchanges illustrate how heterogeneity, diminishing returns to scale, and multi-homing determine whether network effects translate into real, defensible power and value capture.

IDEAS WORTH REMEMBERING

Power is a second invention after product-market fit.

Helmer frames company value as two independent step-changes: first create value (PMF), then keep a defensible share of it (power). Many platforms excel at the first while failing at the second because friction reduction also lowers barriers to entry.

Define platforms by transactions, not technology.

Shi defines a platform as an intermediary for transactions, spanning everything from ancient village matchmakers to Uber. Digital tech matters not because it “is” a platform, but because it collapses transaction costs (search, input, coordination, payment) and makes new transaction patterns viable.

Use three questions to diagnose platform power.

(1) Map how economic value is created and how it changes with more participants; (2) model how each side/segment perceives that value as scale grows; (3) identify what prevents competitors from matching the value proposition. Together these separate value creation from defensibility.

Heterogeneity determines how quickly scale advantages flatten.

In low-heterogeneity markets (ride-sharing), “good enough” density is reached quickly, so returns to scale flatten early. In high-heterogeneity markets (YouTube content), matching is multi-dimensional and idiosyncratic, so the advantage of more supply/demand persists longer.

Multi-homing is the central threat to platform power.

If riders/drivers (or buyers/sellers) can easily use multiple platforms, any relative scale advantage can be arbitraged away—customers draw value from the combined pool rather than one platform’s pool. Durable power often requires friction, contracts, or other barriers that inhibit multi-homing.

WORDS WORTH SAVING

5 quotes

There are really two major step changes in the value of a company. The first is product-market fit, and the second is getting power.

— Hamilton Helmer

We think of [a platform] as an intermediary for transactions, and that’s it.

— Chenyi Shi

Platforms… you don’t own your customers… This is a scenario that we call multi-homing, and… a lot of the differential value… gets arbitraged.

— Chenyi Shi

When you see a flywheel, run for the hills.

— Hamilton Helmer

Network effects describes only the value creation… without consideration about competition, which… is all power is about.

— Chenyi Shi
