Rethinking Mental Health & Neurology

Ranvier is transforming how we diagnose and treat depression, anxiety, Alzheimer’s, and Parkinson’s by using objective clinical measurement and advanced computational modelling.

TasteDX is the first taste-based screening test for depression. Combined with BioDX, our blood-based biomarker for neurodegenerative risk, we offer scalable tools to detect and monitor brain health with precision. From faster diagnosis to more personalised care, everything we build is designed to improve lives. Whether you are a patient looking for answers, a clinician seeking accuracy, or an investor shaping the future, Ranvier provides the tools to act early and with confidence..

Ranvier is Transforming Care

Ranvier is Transforming Care

1/ We Diagnose Earlier

We identify signals of depression and neurodegeneration up to 10–15 years before symptoms appear. Early detection helps prevent chronic disease, slow progression, and protect long-term quality of life.


2/ We Measure Treatment Response

Ranvier measures how the body reacts to treatment - in real time. A change in taste perception after the first dose can act as a powerful early indicator of whether a therapy is likely to work. This has never been done before.


3/ We Individualise Medicines

Our unique protein biomarkers guide doctors in tailoring to each individual - matching the interventions at cellular level with a high degree of confidence.


A Global Emergency in Mental Health

A Global Emergency in Mental Health

Depression is the most misdiagnosed and undertreated health condition in the world. It affects over 300 million people and is often the first clinical sign of deeper neurological issues such as Alzheimer’s and Parkinson’s. Yet most diagnoses still rely on outdated questionnaires and subjective self-reporting. This gap leaves millions of people without answers or access to timely care. The world needs a new standard for speed, accuracy, and objectivity in mental health. Ranvier is building that standard.
