Network Effects
The phenomenon where a product or service becomes more valuable as more people use it — one of the most powerful competitive moats in technology.
Network effects occur when a product's value increases with each additional user. If one person uses a phone, it has limited value; if millions use it, it's essential. Network effects create powerful, self-reinforcing moats because they're difficult for competitors to replicate from scratch. Types: Direct network effects (social networks — more users = more connections = more value). Indirect network effects (marketplaces — more buyers attract more sellers and vice versa). Data network effects (AI products — more users generate more data, which improves the model, which attracts more users). Network effects are the single most sought-after characteristic in technology investing — companies like Facebook, Airbnb, Uber, and LinkedIn derive enormous value from them. Peter Thiel's Zero to One made network effects a central concept in startup strategy.
