SDTEST® is a behavioral intelligence platform built on the world's largest Spiral Dynamics dataset: 91,000+ assessments, 39 VUCA indicators, 172 countries.

Most behavioral tools explain what has already happened.
SDTEST® is built to answer what happens next.


Three layers. One infrastructure.

Layer 1. Individual assessment
Understand your own value system (vMEMEs) and compare yourself with the global dataset. Free. Takes 5 minutes.

Layer 2. Global behavioral dataset
91,000+ assessments. 8,048 unique behavioral patterns. 13,000+ empirical correlations. Research and Enterprise access for organizations that need to understand how different groups think, react, and change across cultures and time.

Layer 3. SD-Navigator™
A behavioral simulation engine. Input your organization's current vMeme profile and psychological sensors (Fear, Trust, Wellbeing). Choose a management action.
SD-Navigator™ computes what happens next: which value systems destabilize, where trust collapses, and which path produces the most stable outcome.

Test decisions before they hit reality.

Used by researchers, organizational psychologists, HR strategists, and leadership teams who need more than a dashboard.
