Why does Network Effects matter?
It is the most durable competitive position a company can have, and the most over-claimed. A genuine network effect means a competitor with a better product can still lose, because what your users want is the other users. That changes what you optimize: getting one dense pocket connected matters more than getting the same number of users scattered, and the early period where the product is not yet useful has to be survived deliberately rather than discovered by surprise.
What does Network Effects look like in practice?
Suppose two products each reach ten thousand users. In the first, a marketplace, every new seller makes it more worthwhile for buyers to look, and every buyer makes listing more worthwhile, so the ten thousandth user arrives to something far better than the hundredth did. In the second, a note-taking app, the ten thousandth user gets exactly the product the hundredth got. Both grew; only one got harder to displace while doing it.
What are the common mistakes with Network Effects?
- Calling any growth loop a network effect. Word of mouth, virality, and brand all help you acquire users; a network effect means the product itself gets better as they arrive.
- Ignoring the cold start. A networked product is least useful on the day it launches, so the plan has to include how the first pocket becomes valuable before it is big.
- Assuming the effect is global. Most are local: density inside one city, one company, or one profession is what creates value, and a scattered user base of the same size creates none.
- Forgetting that they can run in reverse. The same mechanism that compounds an advantage compounds a decline once users start leaving.
