When you're building a social app, you're actually building three products: the core, the graph, and the growth.
The Core is what users do and feel inside the app. It’s the easy part — it’s the “I have an idea for an app” that friends call you excited about.
The Graph is the network — how they find friends, connect, interact, and stay tied together. A great graph makes the app sticky and essential.
The Growth is the engine — how the app spreads naturally, how new users find it, and why they stick. Growth has to be designed, not hoped for.
