We built the test we wish our parents had taken.
Every founder of Compatibilio is the child of a divorce, the witness of a quiet separation, or the friend who watched two good people slowly become strangers. This is the product we needed twenty years ago.
In 2019, three of us — a clinical psychologist, an engineer, and a designer — sat in a kitchen in Lisbon trying to explain to one friend why his marriage had ended. He had done nothing wrong. Neither had she. They were simply two operating systems that had never been installed on the same machine.
We started reading. Forty years of longitudinal couples research. The work of John Gottman at the University of Washington, the attachment theory of John Bowlby and Mary Ainsworth, the OCEAN personality model of Costa and McCrae, the self-determination theory of Deci and Ryan. Everything we needed already existed. It was just locked inside academic journals, expensive therapists' offices, and twelve-hour weekend workshops nobody ever attended in time.
The question became simple: what if the most important conversation of your life took forty-five minutes, splittable, and lived in your pocket?
For four years we shipped nothing. We sat with therapists, relationship researchers, and ninety-two couples who let us audit their entire history of repair and rupture. We rebuilt the question bank eleven times. We threw away two hundred features that felt clever but didn't change a single outcome.
What we kept is what you see today: two hundred validated questions, one honest report, sixty seconds a day to keep the right relationship healthy. No swipes. No streaks. No gamified intimacy. Just a calm instrument that tells you the truth a year before you'd find it out the hard way.
— The founders of Compatibilio
Three principles we won't trade for growth.
Principle 01
Honest over flattering.
A flattering result that costs you seven years is the most expensive thing software can sell you. We will always tell you what the data says — even when it's 'not yet.'
Principle 02
Clinical, not clinical-feeling.
Every screen is grounded in peer-reviewed instruments. None of them feel like a hospital. Warmth is the delivery vehicle for rigor.
Principle 03
Your data is yours.
We don't sell it, we don't advertise against it, and we never train models on it without explicit, revocable consent. Delete in one tap. We mean actually delete.
Seven years of slow, careful work.
2019
The kitchen in Lisbon.
Three founders sketch the first instrument on a napkin. Question one: 'How do you know who you're actually marrying?'
2020
The research years begin.
Partnership with two European universities. Question bank cross-validated against Gottman's Sound Relationship House model.
2022
Ninety-two couples audit us.
Year-long longitudinal pilot. We predict relationship stability at 14 months with 91% accuracy. We delete features that don't move the needle.
2024
The Daily Pulse is born.
Resentment, not conflict, ends marriages. We ship a 60-second daily ritual that surfaces frictions before they fossilize.
2026
Compatibilio, in your pocket.
Public launch in Europe. Four decades of clinical research distilled into a calm forty-five minutes, splittable across sessions. No swipes. No streaks. Just truth.
"Love is not the problem. The absence of an honest mirror is. We built one."
