Regarding the oral focus: Our core technology is based around the oral microbiome for a number of key reasons.

1. decades of research have shown causal relationships between the oral microbiome and preventable gum disease. 2. the oral microbiome is much lower in diversity than the fecal microbiome, granting the opportunity for the development of relatively low-cost diagnostics that leverage the microbiome. 3. new and exciting studies have shown correlations between the oral microbiome and a number of systemic health indications, which we hope to continue to uncover with our platform.
