If you’ve been reading anything about marketing lately, you’ve probably seen the term “growth loops” everywhere. It can sound like another buzzword, but the idea is actually pretty straightforward. And we’re pleased you’ve landed on this blog, so we can help introduce you to the phrase. Thanks for not clicking away and thinking, “That word again!”
Here’s the short version: A “growth loop” is a system where your existing users or customers help bring in new ones—without you having to start from scratch every time.
Think of it as momentum instead of repetition.
In a traditional model (aka, the beloved funnel), you run a campaign, generate leads, convert them, and then start over. It’s linear. Once the campaign ends, the results stop.
A growth loop, on the other hand, feeds itself.
A simple example is referrals. A customer has a good experience, tells a friend, and that friend becomes a customer. Now you have two people who can refer others. Over time, that compounds.
Content can work the same way. You publish something useful, people find it, share it, or link to it. That brings in more traffic, which leads to more visibility, which brings in even more traffic.
The key difference is that each action creates the conditions for the next one.
That’s why marketers are paying more attention to loops. They’re more sustainable. Instead of constantly pouring resources into new campaigns, you’re building systems that keep working in the background.
That doesn’t mean loops replace everything else. You still need acquisition strategies, especially early on. But the goal is to gradually shift from “push” to “pull.”
Another reason this concept is gaining traction is efficiency. As customer acquisition costs rise, businesses are looking for ways to get more out of what they already have. Growth loops do exactly that: turn existing customers, content, or product features into distribution channels.
Not every business will have the same loops, and they don’t appear overnight. You have to design for them.
Ask yourself:
- What actions do our customers take that could naturally lead to more customers?
- Where are people already sharing or engaging?
- How can we make that easier or more rewarding?
Sometimes it’s as simple as adding a referral incentive. Other times, it’s building sharing into the product itself. One great example is Substack’s “restack” feature, which encourages users to repost each other’s content. Another is the Substack referral system, where creators can reward their subscribers for inviting others to subscribe.
Once a loop starts working, it can become one of your most valuable assets. Because, unlike a campaign, it doesn’t end.
In our next post, we’ll take a deeper dive into the difference between growth loops and funnels so that you can choose which approach works best for you—although, reminder, you don’t need to choose just one!
