Know who you're
actually loving.
Most couples discover their real differences years too late. Compatibilio is the forty-five-minute instrument that surfaces them now — honestly, privately, and without ever flattening you two into a fake percentage.
Module 01 · Attachment
Mapping the biological blueprint of how you connect, stay, and resolve tension.
Calibrated honesty
Every dimension carries its own confidence. When we're less sure, you see it.
Question 56 · Conflict style
After a fight with my partner…
I withdraw and need space
I want to talk it through immediately
I get anxious until we reconnect
I pretend it didn't happen

Every result shows its own confidence. When we're less sure, you see it. No other test dares.
Compatibilio measurement model
Three questions. A small sliver of you.
She reads it differently.
So does he. We built for both.
The Compatibility Test.
120+ research-grade questions, adaptively selected.
One honest map of the two of you.
Both partners take it separately, forty-five minutes, splittable. You receive a forty-page report — the kind a therapist would write — that names exactly where you fit, where you'll friction, and the five conversations to have before anything binding. Read it together, out loud, with coffee.
Compatibility Report
Andrew & Maya
"Conflict style is the friction point. Five honest conversations before you sign a lease — prompts on page 27."
One sample couple. Twelve real dimensions.
Tap any pair of stars. Each thread is a dimension we measured between them — the closer they sit, the more aligned. Yours will look like nobody else's.
A diary keeps your feelings.
Pulse delivers them.
The things you'd never say to their face, said anyway — softly, on time, in your words or better ones. One dial. One feeling. One unsaid thing, bridged by morning. Resentment is what kills marriages — not fights.

"How partners see each other predicts the relationship better than any personality trait. So we measure both of you — and the space between you."
From the findings of Joel et al., PNAS · 2020
We didn't invent the science. We translated four decades of peer-reviewed work — Gottman, Bowlby, Hazan & Shaver, Costa & McCrae, Deci & Ryan — into a fifteen-minute conversation you can have in your pocket.
A different category of product. On purpose.
Unlike dating apps,
we don't optimize for swipes or screen time. We optimize for the truth — even when the truth is 'not yet'.
Unlike therapy apps,
we work with both of you, every day, in sixty seconds. The hygiene before the surgery.
Unlike everyone else,
you own your data. We don't sell it, we don't advertise against it, and you can delete it in one tap.
Built for couples. Vetted by clinicians.
The most thoughtful pre-commitment assessment I've put in front of clients. It surfaces the conversations couples were already circling — without the shame.

I send couples here before our first session. They arrive with a vocabulary for what they're feeling, and we get to the real work in week one instead of week six.

Rigorous without being clinical-cold. The report reads like a kind, well-prepared third party at the table — which is exactly what most couples need.

The test that tells you
when it isn't sure.
Every dimension in your report carries its own confidence. Fewer answers, mixed signals, a rushed stretch — you'll see softer edges, and one tap explains why. That's not a weakness of the instrument. It's the difference between measurement and astrology.

Low — needs more

Andrew and Maya were beautiful together. They were also the wrong two people.
They met at twenty-six. Andrew was steady and quiet, the kind of person who needed a long walk to think. Maya was bright and fast, the kind of person who said the hard thing first. Everyone loved them as a couple. Their wedding photos still circulate.
Year one of marriage exposed what dating had hidden. She wanted to talk things through the night they happened. He needed forty-eight hours of silence. She read his silence as rejection. He read her urgency as attack. Neither of them was wrong. They simply couldn't repair the way the other one needed.
By year four, a mortgage and a dog. By year six, strangers being polite. By year seven, a lawyer.
The brutal part: fifteen minutes of the right questions — answered honestly, before they signed anything — would have shown them exactly this. Not whether to love each other. Whether to build a life together.
We built Compatibilio so the next Andrew and Maya have the conversation before the lawyer does.
