Growth Loops
Replacing linear funnels with self-reinforcing loops where the output of one cycle becomes the input of the next. Creates compounding growth rather than linear acquisition.
When to Use
Use when you've exhausted linear acquisition channels and need compounding growth. Best for products with natural sharing, content creation, or network effects.
Origin & Background
Developed by Brian Balfour (Reforge) and Andrew Chen. Challenged the traditional funnel model by showing that the best-growing companies build loops, not funnels.
Framework Steps
Map Current Loops
Identify any existing self-reinforcing cycles in your product.
Classify Loop Types
Categorize: viral, content, paid, or sales loops.
Measure Loop Metrics
Track cycle time, amplification factor, and loop efficiency.
Optimize the Weakest Link
Find and fix the step with the biggest drop-off in each loop.
Stack Multiple Loops
Layer complementary loops for compound growth.
