Every day, you walk past people who could change your life.

Stop being ghosts to each other.

Serendipity uses Bluetooth to find compatible people within 50 meters of you right now. Not by swiping. Not by scrolling profiles. By detecting psychological resonance across 46 scientific frameworks — entirely on your device, with zero data leaving your phone. The person who thinks like you, builds like you, or sees the world the way you do might be sitting three tables away. You just need the signal.

Privacy-first. End-to-end encrypted. Built on the open Tavern Protocol.

The U.S. Surgeon General declared it a crisis.
The data says it's worse than you think.

We are the most connected generation in history, and the loneliest. Social apps didn't fix this. They made it worse.

58% of U.S. adults report feeling lonely regularly
Cigna Loneliness Index, 2022
1 in 4 adults have zero close friends — double the rate from 1990
Survey Center on American Life, 2021
8,000+ people you pass within 50 meters every month in a typical city — nearly all invisible to you

"We have replaced genuine human connection with a curation of digital personas. Loneliness is now as lethal as smoking 15 cigarettes a day."
— Dr. Vivek Murthy, U.S. Surgeon General, Our Epidemic of Loneliness, 2023

What existing apps do

  • Judge by photos and bios
  • Harvest location data 24/7
  • Optimize for engagement, not connection
  • Make you perform for an algorithm
  • Work for extroverts. Punish everyone else.

What Serendipity does

  • Matches on psychological resonance
  • Zero location data leaves your device
  • Optimizes for encounter quality
  • Learns who you are from behavior, not performance
  • Built for introverts, thinkers, and builders

Five moments between
strangers and connection.

No accounts to fill out. No algorithms watching what you click. Just Bluetooth, proximity, and math running quietly on your phone.

1

Broadcast

Set your transmission — what you're building, what you're curious about, what kind of mind you want to find. Your signal evolves as you do.

2

Scan

BLE beacons detect compatible people within 50-200m. Resonance is scored across 46 psychological dimensions — entirely on your device. No server ever touches the data.

3

Match

A haptic pulse in your pocket. The stronger the resonance, the stronger the signal. Not a notification — a whisper from the mesh that someone nearby is on your wavelength.

4

Encounter

Mutual handshake. Transmissions revealed. You see why the mesh connected you — shared obsessions, complementary skills, aligned values. Meet. Talk. Discover.

5

Connect

Exchange glyphs — one word that captures what the encounter meant. Your mesh history grows. The system learns. Future matches get sharper. The mesh remembers.

Not a social app.
A perception upgrade.

46 psychological frameworks.
Zero data on our servers.

Big Five personality. Schwartz Values. Jungian cognitive functions. Attachment theory. Kegan developmental stages. Polyvagal regulation. Flow-state compatibility. 46 peer-reviewed frameworks, all inferred from behavior patterns, all computed on your phone. The result is a multi-dimensional resonance score that captures something dating apps and LinkedIn have never even attempted: whether two people will actually matter to each other.

It learns who you actually are, not who you say you are.

Most apps ask you to describe yourself. But people are unreliable narrators of their own personalities. Serendipity watches how you interact — which pings you respond to, which glyphs you leave, when your engagement deepens — and builds a behavioral fingerprint that reveals the real you. Including the parts you haven't met yet.

How matching works →
1 Surface Interests, topics, current project
2 Context Skills, experience, domain expertise
3 Character Values, thinking style, communication
4 Shadow Behavioral patterns, growth edges
5 Resonance History, encounter outcomes, glyph patterns

The deeper you go, the more it reveals.

Serendipity doesn't dump your personality on a screen. It unfolds in layers — Surface, Context, Character, Shadow, and Resonance History. Each encounter, each glyph, each pattern of engagement unlocks new dimensions. The app grows with you because it's measuring you growing.

How connection deepens →

It predicts the encounters that will matter.

Not just "you have things in common." Serendipity models flow states, broaden-and-build cascading, and encounter quality trajectories to predict which meetings will actually change the shape of your week. Over time, it learns the difference between someone you'd enjoy coffee with and someone who could alter the course of your life.

Safety isn't a feature. It's the architecture.

Beacon IDs rotate every 15 minutes. All resonance scoring happens on-device. End-to-end encryption means we can't read your data even if compelled. Buddy beacons let a trusted friend monitor encounters. Boundary normalization makes it feel natural to say "not right now." This isn't privacy theater — it's privacy engineering.

We can't sell your data
because we never have it.

Every social app promises privacy. We engineered it so we couldn't violate yours even if we wanted to.

🔒

On-device computation

All 46 resonance dimensions are computed locally. Your psychological profile never leaves your phone.

🔄

Rotating beacon IDs

Your Bluetooth identifier changes every 15 minutes. Nobody — not even us — can track your movements.

🔐

E2E encryption (X25519)

All communications use X25519 key exchange. We cannot read your messages even under legal compulsion.

👁

Zero location transmission

Your GPS coordinates never leave your device. No location history. No heat maps. No geofencing. Nothing.

46 frameworks. 50+ years
of validated research.

Every dimension of the resonance engine maps to peer-reviewed psychological research. This isn't astrology. (Well, there's also optional astrology.) Here are some of the frameworks powering the match:

Big Five Personality Schwartz Values Theory Attachment Theory Jungian Cognitive Functions Polyvagal Theory Flow Theory Broaden-and-Build Kegan Development Self-Determination Theory Interpersonal Circumplex Cognitive Load Theory Social Identity Theory Complementarity Hypothesis Optimal Distinctiveness Terror Management Theory Regulatory Focus Theory Relational Models Theory Need for Cognition Synastry (optional) +27 more

Built for the people who are
tired of being invisible.

You don't need more followers. You need one real conversation with someone who actually gets it.

The builder who needs a collaborator, not a LinkedIn connection.

You're working on something that matters to you. You don't need "networking." You need the one person in your city who understands the problem you're obsessed with — and has the missing piece.

The introvert whose best conversations happen by accident.

You don't do mixers. You don't do apps. But when you end up next to the right person at a bookstore or a coffee shop, something unlocks. Serendipity just makes that accident happen more often.

The neurodivergent thinker who connects through depth, not small talk.

Surface-level socializing drains you. But when someone shares your specific obsession — your niche, your way of thinking — the energy is infinite. The mesh finds your frequency.

The person in transition who needs a witness, not a coach.

New city. New chapter. New identity forming. You don't need advice — you need someone who sees you as you're becoming, not who you were. The mesh doesn't care about your past. It reads your signal now.
