Fourth Vital ^Company

Fourth Vital is building the earliest physiological warning layer for kidney disease.

Chronic kidney disease affects over 850 million people globally and entered the global top-10 causes of death in 2023. Yet 90% of patients remain unaware until irreversible decline is already underway. Conventional lab tests detect damage after irreversible decline has already begun.

Fourth Vital converts an upstream cellular distress signal into continuous AI-driven kidney-risk intelligence embedded within CKD and cardio-renal workflows.

The company is in live IRB-approved in-clinic data collection at a leading hospital kidney unit in Canada and expanding to additional sites.

We are raising a $1.25M Pre-Seed SAFE to scale data collection and prepare initial RUO deployment.
