Growth Loops

This implements the Brian Balfour/Reforge framework for building compounding growth systems instead of linear funnels. The core idea: design loops where each user generates more users, so output becomes input for the next cycle. You'd reach for this when planning your growth engine, moving beyond paid acquisition, or diagnosing why growth isn't compounding despite steady user acquisition. It walks you through identifying loop types (viral, content, sales), mapping mechanics, and finding the variables that actually drive compounding. The framework is most useful after you have some product-market fit but before you've locked into a pure performance marketing mindset. Skip it if you're still validating that anyone wants what you're building.
