What Are Growth Loops?
Growth loops are a marketing framework designed to create self-sustaining cycles of growth. Unlike traditional marketing funnels, which move customers linearly from awareness to conversion, growth loops are circular and iterative. Each user action triggers another action, creating a compounding effect that drives continuous growth.

Why Loops, Not Funnels?
Funnels are linear and require constant investment at the top to maintain growth. Growth loops, on the other hand, are self-reinforcing. Each user action contributes directly to acquiring more users, creating sustainable, compounding growth.
Additionally, growth loops are typically embedded directly into your product experience, making them harder for competitors to replicate.
Where Growth Loops Thrive
Growth loops work particularly well in certain business models. Here are some examples:
| Business Type | Examples | Loop Mechanics |
|---|---|---|
| User-Generated Content (UGC) | Reddit, Quora | Users create content, attracting new users who then create more content. |
| Network Effects or Viral Loops | Dropbox, LinkedIn | Users invite others, expanding the network and driving further invitations. |
| Community-Led Growth | Slack, Discord | Community engagement attracts new members, who further enrich the community. |
| Sales Loops | Salesforce, HubSpot | Revenue from sales funds expansion of sales teams, driving further customer acquisition. |
Examples of Successful Growth Loops
Here are some well-known examples of growth loops from high-growth companies:
- Dropbox: Users invite friends to earn extra storage, creating a viral referral loop.
- LinkedIn: Users invite professional contacts, expanding the network and attracting more users.
- Zoom: Meeting participants experience the product first-hand, prompting them to sign up and host their own meetings.
- Slack: Team collaboration drives adoption; as more team members join, the platform becomes more valuable, encouraging further adoption.
- HubSpot: Free tools and content attract users who then share these resources, driving further inbound traffic and sign-ups.
Growth Loops vs Funnels
Traditional marketing funnels, such as the AARRR framework, guide customers through linear stages from awareness to conversion. Growth loops, however, emphasise sustainable, compounding growth rather than linear progression.
Focusing solely on funnels limits your potential for sustainable growth. Gartner provides further insights in their article on Growth Loops vs AARRR Funnels.
Key Differences Between Growth Loops and Funnels
| Growth Loops | Funnels |
|---|---|
| Self-reinforcing cycles where each action fuels the next | Linear progression from awareness to conversion |
| Encourage repeat engagement and virality | Focus on moving customers through stages towards conversion |
| Continuous, iterative, circular process | Linear, one-directional flow |
| Prioritise ongoing engagement and retention | Prioritise customer acquisition and conversion optimisation |
Main Types of Growth Loops
Viral or Referral Growth Loop
Viral loops leverage existing users to attract new users through referrals and sharing:
- User signs up and experiences value.
- User shares the product with others.
- New users sign up and repeat the process.
Example: Dropbox’s referral programme.
User-Generated Content (UGC) Growth Loop
UGC loops rely on users creating content that attracts new users:
- User creates content on the platform.
- Content is indexed and discovered by new users.
- New users sign up and create more content.
Example: Lemlist’s growth loop, detailed in this case study.
Paid Marketing Growth Loop
This loop reinvests revenue from paid marketing into acquiring more users:
- Acquire users through paid channels.
- Users generate revenue.
- Revenue is reinvested into paid marketing.
Example: HubSpot’s paid acquisition strategy.
Sales Growth Loop
The sales growth loop uses revenue from sales to expand the sales team, driving further growth:
- Sales team acquires new customers.
- Revenue from customers funds hiring more sales reps.
- Expanded sales team acquires even more customers.
Example: Salesforce’s sales-driven growth strategy.
Why Retention Matters for Growth Loops
Retention significantly amplifies the effectiveness of growth loops. Even small improvements in retention can dramatically boost growth:
- Viral loops: Higher retention increases referral opportunities.
- UGC loops: Better retention leads to more content creation, attracting new users.
- Paid marketing loops: Improved retention accelerates revenue reinvestment into paid channels.
- Sales loops: Increased retention generates more revenue, enabling further investment in sales teams.
Our Takeaways
Funnels remain useful for measuring marketing effectiveness, especially in B2B environments with longer sales cycles. However, we strongly recommend combining funnels with growth loops. Your primary marketing efforts should focus on initiatives that compound and deliver sustainable results over time.
