Compatibility Science

The algorithm that finds your person.

Cymbie's matching engine doesn't guess — it calculates. Built on peer-reviewed relationship psychology and trained on data from 2 million real couples, here's exactly how it works.

The Signals

7 dimensions of compatibility.

Not all compatibility factors are created equal. Our algorithm weights each signal based on its proven correlation with long-term relationship satisfaction in academic literature.

The Process

From profile to match in 4 steps.

01

Profile analysis

We process your answers to all profile prompts using NLP to extract values, personality patterns, and communication markers.

02

Signal scoring

Each of your 7 compatibility signals is scored independently using trained models validated against real relationship outcomes.

03

Mutual matching

We only surface matches that score well for you AND for whom you score well — compatibility is always bilateral.

04

Ongoing learning

As you interact — liking, commenting, messaging — our model learns your real preferences and refines future recommendations.
