About SparkBetween
A research-backed framework for genuine discovery — built on decades of clinical science, designed to deepen connection through honesty and care. Founded in 2025 by a team of relationship researchers and clinical sexologists.
Our questionnaire is built on decades of research in sexual health, desire theory, and relationship science. Drawing from the Journal of Sexual Medicine, the responsive desire framework developed by Dr. Emily Nagoski, and modern clinical sexology, we’ve created a comprehensive exploration tool that covers 15 dimensions of intimacy across 278 carefully crafted questions.
After both partners complete the questionnaire independently, our AI engine cross-references your responses across all 278 dimensions. It identifies three categories of connection:
The result is a personalized Mutual Discovery Reportthat reveals only what you’re both comfortable with.
Your individual responses remain entirely private. Only mutual discoveries — things both partners expressed interest in — appear in your shared report. If one partner says no to something, that preference stays completely private. We believe that honest exploration requires the safety of knowing your boundaries are respected.
