Delight Is Not Confetti

Nesrine pushes back on the common belief that delight means sprinkling animations, snowflakes, or confetti on a product. She calls this the 'confetti effect': surface flourishes with no underlying value. Confetti is fine when it carries meaning, as with Airbnb celebrating a renewed Superhost badge, but empty of value it should be dropped.

  • The 'confetti effect' is delight mistaken for decoration
  • A shake-the-phone snowflake animation isn't the delight she means
  • Delight must come with a concrete reason and value
  • Confetti with meaning (Airbnb Superhost renewal) is worth keeping

And I call this like the confetti effect. Like people think about confetti as a way of delighting their users.

But if it doesn't bring any value, then don't do it.

When Delight Backfires: The Inclusion Trap

Delight done without inclusion can hurt people. Nesrine cites Deliveroo's Mother's Day notification in France, designed to look exactly like a missed call from your mom, which drew terrible press because for some users it meant grief, not joy. She adds Apple's gesture-triggered reactions: during a Google Meet, a person showing a therapist a hurt finger accidentally set off fireworks on screen.

  • Deliveroo's Mother's Day push mimicked a missed call from your mom
  • What sparks joy for some means grief or sorrow for others
  • Inclusion belongs on the delight checklist to avoid this
  • Apple's gesture reactions fired fireworks during a therapy call about a hurt finger
  • Google Meet users complained and had to disable it at the OS level

It It was supposed to be delightful. The problem is that this feature had the worst press ever in France.

or sorrow or whatever. So, it was not inclusive enough.

Hot Take· 1

Hot Take22:00

B2H: Delight Matters in B2B Too

Nesrine rejects the assumption that delight is only a B2C concern. She coins 'B2H' (business to human): as long as a human uses the product, their emotions deserve to be honored. After a mostly B2C career, she interviewed people at GitHub, Atlassian, and Snowflake and found each values emotional connection, just under different names (Dropbox's 'cupcake', Snowflake's 'superhero').

  • 'B2H' = business to human; humans use B2B products too
  • GitHub, Atlassian, Snowflake all value emotional connection
  • Dropbox calls its principle 'cupcake'; Snowflake calls its 'superhero'
  • Exposure to great B2C raises expectations for B2B experiences
  • A product that merely works loses to a competitor that also honors emotion

as long as there are human using the product at the end of the day then they need their emotion to be honored.

Nesrine Changuel · 22:30

For me it's really important to take into consideration human emotion while building the product whether in a B2B space or a B2C space.

Delight Defined: Joy + Surprise, Emotional + Functional Needs

Nesrine reframes delight not as decoration but as products that satisfy both a functional need and an emotional one at the same time. Drawing on the psychologist Plutchik's wheel of emotions, she defines delight as the combination of two feelings: joy and surprise. In a crowded market, she argues, delight has shifted from luxury to differentiator.

  • Delight = joy + surprise (from Plutchik's wheel of emotions)
  • The best products connect functionally AND emotionally
  • Even a well-functioning product can stall on growth if it ignores emotion
  • Spotify Wrapped, mood-based recommendations, and Discover Weekly make users feel seen and heard
  • In a crowded market delight is a strategy for loyalty, word of mouth, and revenue

So the light is actually this ability to create products that serve for both emotional need and functional need.

Nesrine Changuel · 07:00

So, these two emotions are joy and surprise.

Humanization: If Your Product Were a Human

Nesrine's favorite 'delighter' is humanization, asking: if my product were a human, how would the experience be better? At Google Meet during the pandemic, the team benchmarked not against Zoom or Teams but against an in-person conversation. Dyson's product head told her they compare their vacuum not to other robots but to a real person you'd hire to clean your house.

  • Humanization asks how a human would deliver the experience
  • Google Meet benchmarked against a real in-room conversation, not competitors
  • Dyson compares its robot to a hired human cleaner, adding room-by-room recommendations
  • The goal is reminding users a real human stands behind the product

If my product was a human, how would the experience would be better?

Nesrine Changuel · 24:30

comparing Google Meet to how this experience of meeting could be better if we were all having this conversation in a row.

The Uber Refund That Turned Anger Into Delight

Rushing to catch a Paris-to-London train, Nesrine's Uber driver cancelled, she grabbed another taxi, and was then wrongly charged for a waiting-and-trip fee. Braced to write a long complaint email, she instead found the refund took just two clicks. The moment where emotion should have bottomed out became a delight because the friction was removed.

  • A 'valley moment' of stress was defused with a two-click refund
  • Removing friction where users expect pain is a core delight lever
  • Lenny's takeaway: making an expected-hard task easy (like cancelling a subscription) is delightful
  • Reducing that stress makes the user more willing to keep using the product

But what happened is that when I get to the app, there have been only two clicks to get refunded.

delightful. like cancelling a subscription, unsubscribing from something.

How Revolut's eSIM Won Over a Skeptic in Singapore

Nesrine resisted her husband's push to switch to Revolut for years. On a family trip to Singapore, facing sky-high roaming fees, he opened a Revolut tab labeled eSIM and bought data for 7 euros in seconds. Because most Revolut users are travelers and expats, the app anticipated a need before she ever asked, a surprise that finally converted her.

  • A banking app shipping an eSIM feature seems absurd until you consider its traveler user base
  • Anticipating needs is the 'surprise' half of delight
  • Superhuman's Rahul Vora: set the bar higher than users set it for themselves
  • Anticipation converted a long-time skeptic into a user

how the hell did revolute thought about putting an eim for a bank app I mean it's really insane

Nesrine Changuel · 16:30

in order for a product to be loved, you need to set the bar higher than your users themselves.

Airbnb Superhost: Delight That Never Moved the Metrics

Lenny reveals he built Airbnb's Superhost program, which came not from a metric to move but from hotelier Chip Conley's idea that you need a way to signal status and quality. The team feared it would tank search conversion; instead it made hosts genuinely happy while, curiously, not moving any metrics. A rare case of delight worth doing even without measurable lift.

  • Superhost originated from Chip Conley's hospitality instinct, not a KPI
  • The team feared it would hurt search conversion
  • Hosts wanted the badge for its own sake ('I want to be superhost')
  • It made hosts happy but didn't measurably move metrics

built the Superhost program. That was one of my projects at Airbnb.

Lenny Rachitsky · 20:30

Uh it didn't actually move any metrics which is interesting.

Buffer Emailed Inactive Users Offering Their Money Back

Nesrine shares a Buffer example: noticing about 2% of users had been inactive for months, the company emailed them offering a refund, deliberately choosing to lose money. The move built trust and integrity, and paradoxically deepened the connection, prompting some users to stay rather than cancel. A B2B illustration that emotional connection compounds over time even without an immediate metric bump.

  • Buffer proactively offered refunds to ~2% inactive users
  • Choosing to lose money signaled trust and integrity
  • Inviting people to cancel can deepen loyalty and reduce churn
  • Brand and personality built this way pay off over time, not instantly

Hey, we noticed that you're not using our product. Are we going to refund you?

Nesrine Changuel · 28:00

So, this is a B2B space. This is about creating trust.

The Discover Weekly Bug That Users Loved

Discover Weekly was designed to be pure discovery, only tracks a user had never heard. After launch, metrics soared, but engineers found a bug injecting familiar, already-liked songs into the playlist. When they fixed it, all the success metrics dropped. Users didn't love the novelty; they loved the accidental familiarity, so the version people enjoy today is the 'buggy' one.

  • Discover Weekly was meant to be 100% new music
  • A bug randomly mixed in familiar, previously-liked tracks
  • Fixing the bug caused all success metrics to fall
  • Familiarity, not pure novelty, drove the love, so the 'bug' was kept
  • This is why 'familiarity' sits on Nesrine's delight checklist

actually the bug was that sometimes the algorithm was injecting some of the like it song.

Nesrine Changuel · 44:00

So they fixed the bug and now with discover weekly that you're enjoying is a buggy version if we can say.

Chrome Inactive Tabs: Delighting People With 99+ Open Tabs

Tackling Chrome's hardest problem, tab management, Nesrine's team discovered users have a real emotional relationship with their tabs, some feeling shame or apologizing for having so many. Rather than closing tabs, they built iOS 'Inactive Tabs', which files away tabs untouched for 21+ days into a folder. Users get a cleaner grid and less stress while keeping trust that Chrome never deleted anything, an example of deep delight.

  • Tab management, not memory, was Chrome's hardest problem
  • Users treat tabs as reminders and to-dos and feel shame about the count
  • Chrome caps the display at '99+' rather than showing three digits
  • 'Inactive Tabs' auto-files tabs untouched 21+ days without deleting them
  • Solving a functional need plus the emotional one = deep delight

there is a relationship between people and their tabs and I really say relationship

Nesrine Changuel · 48:30

that's an example of deep delight where at the same time you're solving for uh a functional need and at the same time including the…

Fighting Zoom Fatigue by Hiding Your Own Face

Joining Google Meet a month before COVID hit Europe, Nesrine's team identified three 'demotivators': boredom, low interaction, and Zoom fatigue. A Stanford study found a major cause of fatigue was seeing your own self-view, like walking down the street with someone holding a mirror beside you. So they let users minimize self-view, and added emoji reactions to restore low-friction interaction.

  • Sometimes it's easier to identify demotivators than motivators
  • A Stanford study tied Zoom fatigue to seeing your own self-view
  • Solution: minimize self-view while still broadcasting your video
  • Emoji reactions (wave, thumbs up) let people feel present without unmuting

It's not about seeing others, it's the fact that you see yourself.

Nesrine Changuel · 53:30

just imagine yourself walking on the street and someone is holding a mirror next to you.

Don't Try to Convince Leaders About Delight, Align With Them

Nesrine's advice for getting buy-in: don't try to convince, which reads as a threat to how the org already works. Instead align delight to what the leader already values (perception vs. perspective). Coaching a founder whose startup helped musicians find curators, she asked whether users were proud to use the product; that single question shifted his entire strategy toward making users proud.

  • Trying to convince a skeptical leader is 'a lost battle'
  • Distinguish perception (your view) from perspective (their world view)
  • Find what the leader values most and connect delight to that goal
  • One question, 'are your users proud to use your product?', reframed a founder's whole strategy
  • That founder pivoted to making users proud and grew into the US market

The very first advice is to try not to convince.

Nesrine Changuel · 55:30

Are they proud enough to tell others artist and musician to use your product?

The 50/40/10 Rule for Allocating Delight

To end the 'delight vs. functionality' debate, Nesrine offers a guidance ratio she calls 50/40/10 once you've sorted your backlog into low, deep, and surface delight. Fifty percent should go to functionality-only (low delight) because a product has to work, forty percent to deep delight where functionality is built with emotion in mind, and only ten percent (roughly two features a year) to pure surface delight.

  • Move from delight vs. functionality to delight IN functionality
  • 50% low delight = pure functionality, because the product must work
  • 40% deep delight = functionality built with emotion woven in
  • 10% surface delight = ~two joy-only features a year for brand and personality

50% of your features should be for low delight.

Nesrine Changuel · 1:01:00

40% for deep delight where actually functionality is there.

The Habituation Effect: Surprise Wears Off Unless You Refresh It

A surprise delights only once; over time it becomes normal, the 'habituation effect'. Part of Nesrine's delight checklist is having a plan to maintain the surprise. Google Meet's background feature is her example: it evolved from blur, to static image, to video background, to immersive moving backgrounds, and now AI-generated ones, keeping the delight alive continuously.

  • Surprise loses its effect over time (the habituation effect)
  • The delight checklist asks whether you can sustain delight over time
  • Google Meet backgrounds evolved: blur to static to video to immersive to AI-generated
  • Snapchat's whole strategy was out-innovating rivals with constant new features

the surprise has an effect that vanish over time. So there's this thing that is called habituation effect.

Nesrine Changuel · 1:07:00

when we introduced background replace in Google meet we first introduced like a blur then we added static image then we allowed for video background
