## Definition
Network Effects occur when a product or service becomes more valuable to its users as more people use it.

## Architectural Mechanics & Deep Dive
Network Effects occur when a product or service becomes more valuable to its users as more people use it. This phenomenon creates a powerful competitive moat for startups, as seen in marketplaces, communication tools, and social platforms, where scaling the user base exponentially increases utility and defensibility.

## Industry Applications & Real-World Use Cases
Building strong competitive moats and driving viral scalability

## Frequently Asked Questions

### Why are network effects highly valued by venture capitalists?
They build organic moats. As a network grows, it becomes harder for competitors to copy or steal users, leading to high margins and scale.

### What is the difference between viral growth and network effects?
Viral growth is about rapid user acquisition (how fast users join). Network effects are about product utility (how much value they get after joining).
