The environmental health intelligence company

Cited health intelligence — environmental health, biomarkers, longevity.
Verified sources, hallucination-free, citation-backed biomedical insight.

A precision, cited health API for digital health platforms, insurers and population-health teams. Send a location and a condition for real-time environmental risk — or a biomarker or longevity signal with no location at all — and the same engine returns the peer-reviewed evidence behind it.

Cited evidence is the trust mechanism.

It turns your platform's data into a reason for users to act.

of chronic disease risk is environmental

70–80% of chronic disease burden is environmental.

The exposome — the totality of environmental exposures across a lifetime — drives the majority of chronic disease risk, yet no platform connected it to cited, usable insight. vasus.ai does — and now extends the same rigour to biomarkers and longevity, with or without the environment.

Rappaport & Smith, Science (2010) — "Environment and disease risks" ↗

The moat is the evidence.

How we compare to the alternatives — vasus.ai always uses verified sources, hallucination-free insight. Every assertion cited. Updated weekly.
