# Growth Loops

> Design and optimize growth loops (viral, content, sales, usage) where outputs of one cycle feed the next for compounding growth. Use when moving beyond one-off funnels toward sustainable, product-integrated growth systems.

# Growth Loops

## Overview

Funnels leak; loops compound. A growth loop is a closed system where the output of one cycle becomes input for the next — e.g., users invite users, content attracts users who create content, usage generates data that improves the product.

## When to Use

- Designing sustainable growth engines
- Improving viral, referral, or collaborative mechanics
- Integrating growth into the core product experience
- Evaluating where to invest for compounding returns

## Common Loop Types

- Viral / referral loops
- User-generated content loops
- Sales-assisted loops
- Usage / data network loops
- Paid acquisition loops (with efficient reinvestment)

## Principles

- Map the loop explicitly: input → action → output → reinvestment
- Optimize the weakest step in the loop
- Measure cycle time and conversion at each stage
- Prefer loops embedded in natural product value, not bolted-on gimmicks

## Verification

- [ ] The loop is diagrammed with clear stages and metrics
- [ ] Each stage has an owner and improvement plan
- [ ] The loop produces net-new growth, not only recycling existing users
