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
2. Usage Loop
Users create content or value within the product, then share it, which invites new users or drives re-engagement.
- Mechanism: User creates → Shares creation → Others consume → Become engaged users
- Example: Twitter threads, Medium articles, Notion templates shared publicly
- Strength: Growth tied directly to product usage and network effects
- Challenge: Requires content creation friction to be very low
3. Collaboration Loop
Users invite colleagues to co-create or collaborate within the product, expanding the user base within organizations.
- Mechanism: User creates → Invites colleagues for collaboration → Colleagues discover product value
- Example: Google Docs invitations, Figma team projects, Slack channels
- Strength: Deep organizational penetration and high retention
- Challenge: Works best for collaborative/team-based products
4. User-Generated Loop
Users discover new content or features through other users' creations, then create and share their own content.
- Mechanism: User discovers content → Creates similar content → Shares creation → Others discover
- Example: TikTok, Pinterest, YouTube trends driving creator participation
- Strength: Creates content flywheel and network effects
- Challenge: Requires critical mass of quality content to sustain
5. Referral Loop
Users invite other potential users in exchange for rewards, incentives, or social recognition.
- Mechanism: User refers → Referred user joins → Referrer gets reward → Shares more referrals
- Example: Dropbox referral bonus, Uber rider referrals, PayPal signup bonuses
- Strength: Directly incentivizes acquisition; easy to measure ROI
- Challenge: Requires valuable incentive without eroding unit economics
How It Works
Step 1: Define Product Value
Clarify the core value users experience:
- Primary action users take in your product
- Value created per user action
- Network effects present (if any)
- Friction points in the experience
Step 2: Evaluate Loop Fit
Assess which growth loops align with your product:
- Product type (collaborative, content-based, utility, etc.)
- Target user behavior and sharing habits
- Network effects already present
- Existing user base and engagement
Step 3: Design Loop Mechanics
Create specific loop implementation:
- Trigger that initiates sharing or invitations
- Incentive for participation (intrinsic or extrinsic)
- Ease of sharing mechanism
- Conversion rate from invite to activation
- Frequency of loop repetition per user
Step 4: Calculate Loop Coefficient
Estimate growth velocity:
- Invites/shares per user per cycle
- Conversion rate of invites to new users
- Net new users per cycle
- Time per cycle iteration
Step 5: Build the Loop
Implement the highest-leverage loop first:
- Start with the most natural loop for your product
- Optimize messaging and friction
- Measure loop metrics and conversion rates
- Compound results over time
Input Format
Use $ARGUMENTS to pass:
- Product description and primary user action
- Target user demographics and behavior
- Existing sharing/collaboration features
- Current growth channels and metrics
- Constraints or opportunities
Output
A growth loops analysis including:
- Ranked evaluation of all 5 loop types for your product
- Recommended primary growth loop with implementation plan
- Secondary loops to layer over time
- Key metrics and measurement framework
- 30-60-90 day implementation roadmap
- Potential loop coefficient and growth projections
Framework
Based on growth loops research by Ognjen Bošković. Focuses on compounding user acquisition through built-in, product-native sharing and collaboration mechanisms.
Tips
- Start with one loop and master it before adding complexity
- Viral loops compound fastest but take time to build
- Collaboration loops create strongest retention and LTV
- Measure loop health weekly during optimization phase
- Combine loops for multiplicative effect once operating at scale
