Oral microbiome intelligence · Southeast Asia
Know your mouth.
Protect your future.
One saliva sample, read by AI, mapped to the bacteria that signal risk — for your mouth and the diseases it predicts. Built for Southeast Asia.

About us
Reading the mouth to read the body.
Orvana reads the oral microbiome — the bacterial community living in your mouth — and turns it into a risk readout you can act on. We started in Singapore in 2025 because Southeast Asia carries the disease burden and almost none of the early-warning infrastructure.

MissionPrevent disease, by data
VisionSEA's oral-health layer
The problem
Treated after it shows up.
Most chronic disease is caught late. 3.5 billion people live with oral disease, and the bacteria in the mouth — early signals for periodontal, cardiovascular and metabolic disease — are almost never read.
By the time symptoms appear, the cheapest window to intervene has closed. Orvana opens that window earlier, with a saliva sample and AI.
Caught late
Symptoms surface only after the cheapest window to act has already closed.
Siloed care
Dental and medical data rarely connect, so oral warning signs are missed.
Costly downstream
Emergency treatment and complications cost far more than early prevention.
Platform
From saliva to signal.
One integrated pipeline — non-invasive collection, AI reading microbial markers, and a report a clinician or consumer can act on the same day.
Test kit
Non-invasive saliva collection — the entry point to personalised microbiome intelligence.
AI engine
Proprietary models reading thousands of microbial markers in parallel.
Health intelligence
Risk scores and recommendations for individuals and clinicians.
Research
Microbiome data for academic and clinical-trial work.
Clinical pathways
Future diagnostics and therapeutics informed by the data.
Opportunity
A market opening early.
Preventive healthcare, AI diagnostics and the oral microbiome are converging — and Southeast Asia is under-served across all three.
Research
Built on evidence.
Peer-reviewed science, university collaborations, and a roadmap toward clinical-grade diagnostics — not claims ahead of the literature.
Output
Peer-reviewed publications
Contributing original work on the oral microbiome and its systemic links.
Network
University collaborations
Validation and expansion with leading research institutions.
Programmes
Innovation cohorts
Health-tech accelerators and government innovation programmes.
Roadmap
Toward clinical grade
Expanding biomarker databases and AI models toward diagnostic capability.
