The IKEA Effect: Why Customers Love What They Help Build (and How You Can Use It)

In partnership with

If you’ve ever assembled an IKEA bookshelf, you know the mix of frustration and pride that comes with tightening the last screw. The instructions may be confusing, the process time-consuming, but once the job is done, that bookshelf feels more valuable than the pre-assembled one you could’ve bought elsewhere.

This phenomenon—where people assign disproportionately high value to products they’ve had a hand in creating—is known as the IKEA Effect. First coined by behavioral economists Michael Norton, Daniel Mochon, and Dan Ariely, it highlights a simple but powerful truth: when customers invest effort, they also invest emotion.

For startups and product builders, the IKEA Effect isn’t just an academic curiosity. It’s a lever you can pull to deepen user loyalty, improve retention, and transform customers into advocates. Let’s unpack how it works, why it matters, and how you can apply it to your own products.

What Is the IKEA Effect?

At its core, the IKEA Effect is a cognitive bias: we overvalue things we help create. In experiments, participants who built IKEA furniture, folded origami, or even mixed their own instant cake batter reported valuing their creations more than similar pre-made alternatives.

The underlying psychology is straightforward: effort creates ownership, and ownership fuels attachment. Just as we cherish a hand-knitted scarf more than a store-bought one, customers cherish products they’ve customized, configured, or contributed to.

Why Startups Should Care

In a crowded market, features alone rarely differentiate products for long. What does stand out is how customers feel about their relationship with your product. The IKEA Effect can:

• Boost perceived value: Customers see their effort as part of the product’s worth.

• Increase switching costs: If someone invested time in personalizing or building within your ecosystem, they’re less likely to leave.

• Turn users into evangelists: People proudly share what they’ve created, becoming organic marketers.

For startups competing against bigger players, this bias levels the playing field. You don’t need the biggest product team—you need to design experiences that make customers feel it’s theirs.

How to Apply the IKEA Effect to Your Product

1. Enable Customization

From Spotify playlists to Notion templates, personalization makes customers feel like co-creators. Even simple customization—choosing a color scheme, naming a workspace—creates emotional stickiness.

2. Gamify Setup and Onboarding

Instead of treating onboarding as a hurdle, frame it as creation. Duolingo, for instance, has users set goals, choose languages, and design their learning path from the very first interaction. Each small action builds ownership.

3. Invite Contribution

Communities thrive when users feel they’re shaping the experience. GitHub repositories, open-source projects, or even small feature voting systems make customers feel like their input matters.

4. Build “Light Assembly” Into the Product

This doesn’t mean making things harder. The key is meaningful effort. For example, IKEA provides ready-to-assemble furniture rather than pre-assembled pieces—not to frustrate, but to let customers claim authorship. Digital products can do the same by letting users build dashboards, workflows, or even avatars.

5. Celebrate User Effort

Recognition multiplies the effect. Think about Duolingo’s streak counters or fitness apps that show weekly summaries. When users see their effort acknowledged, their sense of ownership grows stronger.

The Balance: Effort vs. Friction

One caution: the IKEA Effect works only when the effort feels purposeful. Too much complexity can backfire. If assembly instructions are impossible to follow, customers abandon the product instead of valuing it.

The sweet spot is light but meaningful effort—enough to spark attachment, not enough to cause rage-quitting. For startups, this means being intentional: don’t just add steps for the sake of it, but look for ways where contribution enhances the experience.

Real-World Examples

• IKEA: The classic example—furniture assembly builds pride in ownership.

• LEGO: Customers don’t buy blocks; they buy the joy of building.

• Kickstarter: Backers feel part of the creation process, making them emotionally (and financially) invested.

• Canva: Users build designs themselves, leading to a deeper connection than if they simply downloaded pre-made assets.

To Conclude..

The IKEA Effect teaches us that customers don’t just want products—they want a role in creating them. When you design experiences that involve effort, personalization, or contribution, you unlock a psychological bias that strengthens loyalty.

For startups, this is an invaluable strategy. You may not have the resources of a giant competitor, but you can design products that feel personal, that reward effort, and that make customers think: I built this, so I value it more.

In a world of commoditized products, the winners are often those who make customers feel like co-builders, not just consumers.
