Hi, we’re Jona

We're AI experts, clinicians, dietitians and scientists exploring the new frontier of human health.

We’re driven by a desire to uncover the relationships between the microbiome and health to guide patients, doctors and innovators to discovery and action.

We address root causes, not quick fixes

All our cutting-edge sequencing technology, research, and processing is in the pursuit of simple, actionable recommendations that anyone can take to better their health.

Your sample is processed by the premier microbiome analysis lab in the country. Once your microbiome is analyzed, Jona’s artificial intelligence technology compares your microbiome against 60,000 scientific, peer-reviewed medical papers to find associations between your microbiome and diseases, conditions, symptoms and the actions you can take to be most effective.
