“Go Where There Are Network Effects”
“Go Where There Are Network Effects” – Zero to One book, Peter Thiel
A business that has a strong and enduring Network Effect can be a great business to invest in. It is one of my favorite tools in my mental-model toolbox, and is one that I look for and think about often. The best part about a business that has a strong network effect is just like compound interest, it only gets better as the numbers get bigger. The simplest way to describe a network effect is when a product or service becomes more valuable as more people use it. For example, companies like Airbnb, Facebook, Microsoft, PayPal, eBay, Match Group and Twitter all have strong network effects. If a business can profit on this effect the rewards can be quite enormous. It can be a great starting point for investors seeking to find a business that has a wide and deep moat and a long runway for many years ahead.
- People use Airbnb because they know there is a variety of different options to choose from when it comes to renting a place to stay, and “Hosts” list their houses on Airbnb because they know there’s an endless amount of people who are looking to rent instead of staying in a hotel.

You get the point, right? Network effects can become significant after a certain number of users have been reached: this is the “Critical Mass” point. When the critical mass point has been achieved, the value obtained from this network effect can be greater than or equal to the price paid for the effect. What does that mean? It’s the point at which a growing company becomes more efficient, and no longer needs additional investment to remain economically sustainable. Charlie Munger always talks about learning the “big ideas” across many different disciplines, and critical mass comes from Nuclear Physics; where critical mass is defined as the smallest mass that can sustain a nuclear reaction at a constant level. When bringing this phenomenon into the investing world, it is about when a business becomes self-sustaining. Aiming to hit this critical mass point is the challenging part of business. This is why most tech companies are so focused on user growth and are often valued by user-progression, as opposed to traditional valuation …
