Viral Loop
Noun · Startup & VC
Definitions
A product mechanism where user activity naturally exposes or invites additional users, who then repeat the same behavior. Strong viral loops depend on the invitation mechanism being tightly connected to product value, not tacked on artificially.
In plain English: A built-in cycle where current users naturally bring in new users.
Example: "The collaboration feature created a real viral loop because using it required inviting teammates."
