Viral Loop

Intermediate 🚀 Startup / VC

Definition

A mechanism where existing users naturally bring in new users, creating exponential growth without paid advertising. It's the holy grail that almost nobody actually achieves.

Example Usage

Slack has an incredible viral loop—when one person invites another, both benefit, so growth is basically free.

Origin

Concept formalized in the 2000s-2010s startup era; Dropbox and Hotmail are canonical examples

Fun Fact

A true viral loop requires a viral coefficient above 1.0 (each user brings more than one new user), which is rarer than actual unicorns.
