Science From The Field

What A Wild Idea

Relationship science for beautifully complex people.

This is the largest modern undertaking in relationship science—an unprecedented study of how we love, fight, f*ck, and figure it out (or why we don’t).

The insights are fueling a groundbreaking, personalized program.

Want in? You won’t just benefit from the findings—you’ll help shape them.

Be a part of our pioneering studies.

Most relationship advice is built on theories from a time when pantyhose were a workplace requirement, marital duty was a job description, and no one dared say “orgasm” out loud—let alone study one.

They weren’t up against AI-generated porn—or trying to build intimacy in a world where your friends not only know their own attachment style, but their partner’s three ex’s .

So we built the largest real-time study of romantic relationships ever—tracking what couples actually do (not just what they say), including the stuff no one admits, even to their best friend.

The result? A personalized platform that helps you improve how you connect, communicate, have sex, set goals—and actually grow together.

You’ll see how your patterns stack up against couples like you, and across the world.

No recycled advice, no extreme agenda, no retro rules—just real insight and a smarter way to love.

We’re committed to bringing groundbreaking relationship science to the real world.

Our research includes people across ages, sexualities, genders, cultures, and commitment styles—because no one’s love life fits a one-size-fits-all model.

At the core of our approach is a simple belief: better relationships start with understanding your unique patterns, not outdated norms or cultural agendas.
