Keep Them Coming Back

In April 2013, Pieter Levels left the Netherlands on a one-way ticket to Asia.

He was 26, newly graduated with a Master’s in Business Administration and Entrepreneurship.

But the corporate path didn’t appeal to him.

So he sold everything, packed a laptop and a backpack, and set out to figure out another way to live and work.

He began building internet tools from cafes, Airbnbs, and airport lounges - small projects designed to make money while he traveled.

• Remote OK helped people find remote jobs

• Hoodmaps let users tag neighborhoods by vibe

• And then there was Nomad List.

It started as a simple Google Sheet in 2014.

Pieter used it to track which cities were best for digital nomads, comparing things like cost of living, internet speed, and weather.

When he turned it into a website and launched it on Product Hunt, it immediately resonated with a growing group of digital nomads who were asking the same questions.

At first, it was just another project in his “12 startups in 12 months” experiment.

But something stood out.

Unlike the others, people kept coming back to Nomad List.

Users checked it before booking flights, shared updates about where they were, and used it to compare new destinations.

Pieter later described it as a dashboard for how people lived.

That repeat usage made it viable.

By 2024:

• Nomad List had brought in over $5.3 million in lifetime revenue.

• It had 29,000 paying members and millions of monthly visitors.

• And Pieter built and runs it entirely on his own -bootstrapped and with no marketing team.

But why does his story matter?

Because most products don’t fail because no one tries them. They fail because no one sticks around.

We talk a lot about getting users in the door, but retention is what makes everything else work.

If someone signs up but never comes back, it doesn’t matter how clever your campaign was.

And the opposite is also true.

If someone returns every week, even a small user base can compound.

But retention isn’t magic. It’s built.

The Three Stages of Retention

1. Activation: Make the First Moment Count
This is when a user first experiences real value. Not when they sign up or land on your dashboard, but when they actually complete a task that matters.

Slack figured out that teams who sent 2,000 messages almost never churned.

That became their activation milestone.

Most products have a similar invisible threshold. If users don’t cross it, they fade out.

Your job is to figure out what that moment is and guide people toward it fast.

2. Habit Loop: Give Them a Reason to Return
After activation, the real question is: why do people return?

Sometimes it’s fresh data. Sometimes it’s seeing progress. Other times, it’s the pull of a teammate or a shared goal.

The trigger doesn’t matter—email, push, Slack ping—unless it leads to something users actually care about.

If the return action feels empty, they stop clicking.

Nomad List didn’t need daily nudges.

People returned because travel decisions demanded current, reliable info - and that was enough.

3. Expansion: Let Power Users Go Deeper
Some users will go beyond the basics.

They’ll invite teammates, upgrade to paid plans, or integrate your product into their workflow.

That’s the expansion loop, and it turns retention into referrals, upsells, and word-of-mouth growth.

Figma did this well.

Collaboration brought in more users.

And each new design file became a reason for another person to join.

It was baked into the work itself.

Builder’s Playbook: How Duolingo Engineered Return Behavior

When Duolingo launched in 2011, downloads weren’t the problem. Consistency was.

Learning a language takes time, and most people drop off after a few days.

Luis von Ahn, Duolingo’s co-founder, knew that success hinged on getting people to come back, not just sign up.

So the team designed return behavior into the product.

Streaks were one of the first features to stick.

Each day you completed a lesson, your streak extended. And if you missed a day, it broke. That simple mechanic triggered a sense of ownership.

People planned their day around lessons - setting alarms, sneaking in sessions at work, even roping in partners to keep the streak going.

But Duolingo didn’t just rely on the streak.

They layered in progress tracking with XP points, levels, and a visual skill tree.

Lessons were short and adaptive.

And as you improved, the app adjusted.

They also introduced leaderboards and friend activity.

Some users competed for fun, others just liked seeing their progress in context.

Either way, it made daily return feel normal, not optional.

By 2022, Duolingo had over 49 million monthly active users, and most came through organic growth.

They didn’t scale by buying attention. They scaled by building retention that held.

What You Can Take Away as a Builder

• Make your product do the reminding. A well-timed push notification is fine. But the product itself should provide a reason to return.
  

• Help users see progress. Whether it’s XP, drafts saved, or usage milestones—momentum matters.
  

• Don’t add loops for the sake of it. If it doesn’t reinforce core value, it’s noise.
  

• Behavior beats feedback. If people are rearranging their lives to keep using your product, something’s working. Pay attention to that.

Gut Check: How Sticky Is Your Product?

Set aside 30 minutes this week to answer these:

• What’s your product’s activation moment? How many users hit it?
  

• What percentage come back in week two? Week four?
  

• Which features get used again and again?
  

• Do you know which users stick, and why?
  

You don’t need perfect dashboards. Even rough trends can show you what to fix or double down on.

Audience Corner

How many users came back last week?

What’s one thing you can improve this week to make that number go up?

It could be onboarding, notifications, or trimming the stuff no one touches. Whatever it is, test something.

Final Thought

Retention isn’t glamorous. But it’s the difference between a campaign and a company.

If users keep coming back, growth gets easier. If they don’t, you’re stuck in a loop of spending and hoping.
