5 examples of the network effect
The telephone
One phone is useless; the millionth makes every other phone more valuable. The value comes from who else is on it.
Messaging apps
You join the app your friends are already on — which is why one app tends to win a whole region.
Marketplaces
On eBay, Uber, or Airbnb, more buyers attract more sellers, which attract more buyers — a flywheel rivals struggle to break into.
Social networks
A platform is only worth being on if your people are on it, so the biggest one keeps getting bigger.
App stores
Developers build for the platform with the most users; users pick the platform with the most apps. Each side pulls the other.
How to spot it in yourself
- Building something? Ask 'does this get better as it grows?' If yes, reaching critical mass is the whole game — then the flywheel defends you.
- Competing against a network-effect incumbent? Don't attack head-on — win a niche it serves poorly and build your own dense network there.
- As a user, notice when you're staying on a platform because everyone's there, not because it's good — that's the moat, not the merit.
