For Practitioners

Two tools your practice can use today

Both tools use the same six-domain framework, ensuring consistent language across each.

Free · Individual

The OPP — Optimal Partner Profile

Answers the first question for a client: who am I in a relationship? This 10-minute self-assessment identifies their structural type and the blind spots they may overlook. It serves as an effective intake or first-session tool, providing a shared language for deeper work.

First read free, then paid · A specific connection

OPP Compatibility

The natural next step from the OPP, asking: how do I fit with this person? A structured read on how a client and a specific person actually fit across the same six domains, with the friction points named plainly. Useful when a client is weighing a new or current connection.

The RAE — Relationship Architecture Evaluation

Answers the question a couple is really asking: how are we actually functioning together? This structured evaluation reveals how the patterns of two individuals interact across six domains, including alignment, pressure zones, and perception gaps. Use it as a paid intake, a diagnostic tool between sessions, or as a referral for clients to complete independently.

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 are wired and potential blind spots. When clients wish to explore a specific relationship, the RAE illustrates how two patterns interact. This provides a clear, repeatable framework for your work, and you earn a revenue share if clients continue. There is no software to learn or additional overhead; simply send a link.

Who this is for

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

Built on a transparent framework

Both tools assess six research-informed domains: values, emotional regulation, attachment, conflict, lifestyle & intimacy, and long-term vision. They draw on the work of Gottman, Bowlby, Ainsworth, Johnson, and others. This is a practical synthesis rather than a clinical instrument, and we provide transparency into how each domain is weighted and why we rely on more than self-report.
