Koi dating app - two phones showing the brand splash and a personality-first interface with Milo, the AI companion.

The brief

Dating apps have made meeting people easier, but finding the right person still feels surprisingly difficult. Most platforms optimize for attraction and endless discovery, while compatibility comes much later. Koi is a concept product that reimagines dating around personality, psychology and emotional compatibility-designed from the ground up, from the product philosophy and brand identity to every interaction that brings the idea to life.

01

Situation

More choices. Fewer meaningful connections.

Dating apps have made meeting people easier. Finding the right person? Not so much.

Most experiences optimize for discovery and attraction, while deeper compatibility comes much later.

We're matching profiles, not people. Looks. Bio. Job. Interests. Swipe.

We know how someone presents themselves-but very little about how they think, feel, communicate or connect.

Task

Compatibility isn't about just one person.

It starts with two. A great match isn't only about who you are-it's about who you are together.

That became the idea behind Koi. What if dating could go beyond attraction and understand compatibility?

Koi brings personality, psychology and emotions into the way people discover and understand potential partners.

  • Beyond attraction
  • Human compatibility
  • Meaningful relationships

Action

From a thought to a connected dating experience.

I shaped Koi from the ground up. From "One in a Million" to the product philosophy, visual identity and signature interactions that bring the idea to life.

Bubble Discovery - find your one in a million. A playful way to explore compatible people without reducing everyone to another swipe card.

Flip Profile - there are two sides to every profile. See the person they present, then flip to discover how they think, feel and connect.

Personality & Compatibility - know the person behind the profile. Understand how your personalities align, and more importantly, why you might work together.

Weekly Vibe Check - your personality stays, your vibe changes. Capture how you're feeling and what kind of connection you're looking for right now.

Milo - dating doesn't end at a match. An AI companion for questions about dating, emotions, communication and relationships.

Not features. One connected system. Every interaction helps Koi understand you-and your potential match-better. Personality → Vibe → Discovery → Flip → Compatibility → Connection.

Result

Redefining what a successful match means.

Less swiping. Better connections. Instead of optimizing for engagement, Koi is designed around match quality, meaningful conversations and lasting connections.

From one thought to an entire experience. Koi started with a question: why are we still struggling to find compatible people?

I turned that question into a product philosophy, brand proposition and a connected set of interactions built around human compatibility.

You don't need a million matches. You just need your one in a million.
Not only features. One connected system - personality, vibe, discovery, flip, compatibility, connection
Personality assessment - start, question card and result archetype
Profile setup - settings, photo selection and profile preview
Onboarding screens - trial and error, tailor-made matches, verified profiles, decode your patterns

One final thought.

Technology has become incredibly good at helping us meet more people. Maybe the next step isn't helping us meet more-it's helping us meet better.

That belief shaped every decision behind Koi, and it's a mindset I continue to bring into every product I design.
