In the world of product development, we’re constantly balancing two kinds of work: the measurable, needle-moving initiatives and the intangible but impactful touches that users don’t necessarily need, but love. While metric-driven projects tend to grab the spotlight, it’s the seemingly unmeasurable “delight features” that often leave a lasting impression. These small surprises, the value-adds, and the thoughtfulness woven into the product are the things customers remember and talk about, even if they’re hard to quantify. Here, we’ll explore why delight features are crucial for long-term product loyalty and why product management is as much an art as it is a science.
We all know products that seem purely functional—purpose-built, efficient, and measured. These products work, but they’re like having a relationship with a manager. You have a professional loyalty to them, sure, but there’s no depth, no personality, no sense of “I’m sticking around because I actually enjoy this.” Now think of products that surprise and delight—these are like friends who go out of their way to make you smile. You keep coming back to these products not just because they work, but because they make you feel something.
Delight features turn everyday tools into experiences. They may not always fit cleanly into a metric dashboard, but they resonate with users. And over time, that resonance builds trust, creates loyalty, and keeps customers coming back for more.
Here are a few examples that illustrate how delight features build loyalty by creating moments users remember.
Think of the relationship between a product and its users like any human relationship. If you’re only ever transactional, like a manager or service provider, the relationship feels purely professional—something you keep around because it’s functional. But if a product feels like it’s going out of its way to engage with you, like a friend, you develop an attachment that transcends utility. In the same way that friends remember small gestures, customers remember delightful details that add value without needing to. These features create lasting loyalty that goes beyond what traditional metrics can capture.
In marketing terms, delight features often resonate most with early adopters—the passionate users who champion your product to others. When delighted by a feature, these users become advocates, sharing the experience with friends and influencing the broader market. This enthusiasm can even accelerate the technology adoption curve, helping a product reach a wider audience without the typical push.
The science of product management—metrics, KPIs, A/B tests—is undeniably important. But that’s only one side of the role. Product management is also an art, and delight features are where this artistic side shines. Bringing these ideas to life requires understanding user psychology, having an intuitive sense for what will resonate, and finding ways to balance these moments with the more concrete goals of the product roadmap.
Not every delightful moment will neatly fit into a quarterly plan, nor will every feature designed to surprise and delight result in immediate, quantifiable success. But when teams have the freedom to add in these touches, the long-term results are hard to ignore. At Spotify, for example, the development of features like the touch bar integration on MacBooks came about not from a strategic goal, but from an engineer's enthusiasm and a product manager’s willingness to support it. This “delight feature” wouldn’t reach the entire user base, but it resonated with a loyal subset of users, ultimately reinforcing positive perceptions of the product and creating brand affinity.
For any product, the ultimate goal is retention. Functional features and metric-driven work will always be essential for a product’s growth, but they don’t always capture users’ hearts. Delight features can. And even though they might not always “move the needle” in a measurable way, their impact on user loyalty and brand perception is lasting.
When product managers blend science with artistry, balancing the calculated with the unexpected, they create products that feel more human. Delight features, despite being hard to quantify, bring products closer to the people who use them. In the end, that’s what keeps users around: not just the tools they need, but the experience they love.
