Network effects mean a platform's value isn't fixed — it grows with every user who joins, which is what lets an early lead snowball into lasting dominance.
value ~ users^exponent (Metcalfe/Reed-style law)
adoption accelerates with value
- Platform users — users currently on the platform, each a network node.
- Network connectivity — how directly users interact with and value each other's presence.
- Adoption rate — the baseline rate new users try the platform.
- Network-value exponent — how superlinearly value scales with user count — higher means a stronger winner-take-most dynamic.
This is exactly why a handful of platforms dominate categories like social networking or ride-sharing — once network value compounds past a threshold, latecomers can't catch up.
