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
