Чем growth loop отличается от funnel?

Growth funnel — is a linear model describing the user's journey from the first contact with the product to achieving a target action (e.g., purchase, registration). The funnel shows the stages and the conversion between them, helping to identify bottlenecks.

Growth loop — is a cyclical model where the result of one cycle contributes to the start of the next. For example, a user invites new users, who in turn do the same, creating self-sustaining growth.

Main difference:

• Funnel — linear and focused on conversion at each stage.
• Loop — cyclical, where the output of one stage becomes the input for the next, ensuring exponential growth.

Example of a growth loop: a user shares content, new users register, create their own content, and share again.
