Our mission
Millions are navigating chronic pathogen conditions and post-infectious syndromes that mainstream medicine is still learning to name. The average patient sees 10+ doctors across 4+ years before finding answers. That's not care — that's a maze.
ClearMark Health was born from that maze. Built by patients who lived it, backed by the researchers decoding it, and designed for people whose energy is too precious to waste on a broken system.
Patient-Led
Founded by patients, for patients. Every feature reflects lived experience.
Research-Backed
Six active research priorities tracking the latest breakthroughs.
Compassion-Driven
Community-funded research and a compassion fund for therapies insurance won't cover.
Privacy-First
Your health data belongs to you. Always.
Our programs
ClearMark Health runs three interconnected programs — a patient registry for real-world data, community-funded pilot studies, and research translation for patients and providers.
Symptom tracking, care export, and anonymized data that helps researchers understand chronic pathogen conditions at scale.
Protein biomarker pilot with Attomarker/University of Exeter ($8,500 raised) and customized tragus nerve stimulation research with Vagustim ($7,227 raised).
Recruiting 30 participants to evaluate biomarkers implicated in post-viral illness and establish research-based phenotypes.
How it works
Log symptoms with simple sliders — not paperwork. AI identifies patterns, correlations, and trends you'd miss on your own.
Every relevant study, translated into language you can actually use. Ask questions, get answers — no PhD required.

Research priorities
We track the latest research across every major mechanism driving chronic symptoms in post-infectious syndromes — and translate it into language you can use.
Research into how damaged cells and energy production failures drive chronic symptoms.
Understanding how dormant infections reactivate and contribute to chronic pathogen conditions.
Investigating how viral remnants persist in the body long after acute infection.
Mapping the immune system's misdirected attacks that underlie many chronic symptoms in post-infectious syndromes.
Examining how toxic metal exposure amplifies inflammation and cellular damage.
Exploring the gut-immune connection and how restoring microbial balance aids recovery.
The platform
Every feature built with brain fog, fatigue, and information overload in mind.
Log symptoms with simple sliders, not complicated forms. Our AI identifies correlations between symptoms, triggers, and treatments — surfacing patterns that would take months to notice on your own.
Complex academic studies, translated into clear language you can act on. Ask follow-up questions about any paper and get answers tailored to your understanding — no medical degree required.
