Growth Loops

This breaks down five growth loop types (viral, usage, collaboration, user-generated, and referral) and helps you figure out which ones fit your product. You feed it your product details and user behavior, and it ranks all five loops, recommends which to implement first, and gives you a 30-60-90 day roadmap with projected growth coefficients. It's based on Ognjen Bošković's framework and really shines when you're trying to reduce paid acquisition spend or need to design product-led growth mechanics from scratch. The systematic evaluation of all five loops is genuinely helpful because most teams just default to referral programs without considering whether collaboration or usage loops would compound faster for their specific product.

Growth Loops

Overview

Identify and design growth loops (flywheels) that create sustainable traction. This skill evaluates five proven growth loop mechanisms to reduce reliance on paid acquisition and build product-led growth.

When to Use

Designing growth mechanisms for a product
Building sustainable viral or referral traction
Reducing reliance on paid acquisition
Analyzing competitor growth strategies
Optimizing product for product-led growth

The 5 Growth Loop Types

1. Viral Loop

Product content created by users gets shared on external platforms, bringing new users back to the product.

Mechanism: Users create content in-product → Share on social/external platforms → New users discover and signup
Example: Figma designs shared as links, Loom videos shared in emails
Strength: Exponential user acquisition if content is inherently shareable
Challenge: Requires highly shareable output and strong incentive to share
