For Practitioners

Give your clients a shared language for how they’re wired

The Relationship Stack provides coaches, matchmakers, and therapists a structured way to show clients how they operate in relationships and what to work on first. It is free to use with your clients and offers referral revenue when clients go deeper through your referral.

Two tools your practice can use today

Both are built on the same six-domain framework, so the language carries from one to the next.

Free · Individual

The OPP — Optimal Partner Profile

This 10-minute self-assessment helps clients see their structural type and spot blind spots they might not notice on their own. It works well as an intake or first-session tool and gives you both a shared language before starting deeper work.

Paid · Couple

The RAE — Relationship Architecture Evaluation

This structured evaluation shows how two people’s patterns interact across six domains, including alignment, pressure zones, and perception gaps. You can use it as a paid intake, a diagnostic between sessions, or a referral that your clients take on their own.

What you receive as a partner practitioner

How this fits into your practice

Begin by having clients take the free OPP to reveal how they’re wired and where their blind spots might be. When they want to explore a specific relationship, the RAE shows how two patterns fit together. This gives you a clear, repeatable way to talk about the work, and you earn a revenue share if clients go further. There’s no software to learn or extra overhead—just send a link.

Who this is for

This is designed for relationship coaches, dating coaches, matchmakers, couples therapists, marriage counselors, and content creators who focus on relationships. If your work relies on helping people understand themselves and their relationships, these tools are made to support you.

Built on a transparent framework

Both tools score six research-informed domains — values, emotional regulation, attachment, conflict, lifestyle & intimacy, and long-term vision — drawing on the work of Gottman, Bowlby and Ainsworth, Johnson, and others. It’s a practical synthesis, not a clinical instrument, and we show our reasoning: how each domain is weighted, and why we use more than self-report.
