# What Is Growth Loop?

> A growth loop is a self-reinforcing cycle where user actions generate outputs that attract more users—compounding acquisition or retention without linear paid spend alone.

**A growth loop** is a closed cycle where product usage produces side effects—invites, content, data network effects—that bring in new users who restart the cycle.

## How it works

Classic examples: a user creates a shared document, recipients sign up to edit (viral loop); users publish templates others find via search (content loop); more sellers attract more buyers on a marketplace (cross-side loop). Each loop has steps: input action, output asset, channel for discovery, and new user activation. Loops differ from one-way funnels—they feed themselves when cycle time and conversion rates exceed churn. Product teams instrument loop metrics: invites sent, invite conversion, time to complete cycle. Paid marketing can jump-start loops but sustainable PLG requires the loop to carry marginal users profitably.

## Why it matters

- **Founders:** Design features that complete a loop, not just single-user value. Measure each step before claiming virality.
- **Investors:** Distinguish durable loops from paid-growth disguised as PLG—loops should improve with scale, not saturate immediately.

## Common mistake

Calling any referral discount a growth loop. Without organic discovery or repeatable user-generated output, it is just a promotion—not compounding mechanics.

## FAQ

### What is a growth loop in simple terms?

A growth loop is when using the product creates something that brings in new users—like shared docs, invite links, or user-generated content that others discover.

### Why does a growth loop matter?

Loops can lower CAC and compound growth if each cohort feeds the next. Investors test whether your loop actually closes or just sounds good in theory.
