Evidence built

The federal insider
your evidence needs.

Most RWE consultants advise from the outside. Nyaradzo Longinaker, PhD, MS spent a decade building the analytics that govern CMS programs, CDC demonstration projects, and Medicaid reform — before bringing that institutional knowledge to the commercial side at Elevance Health. The result is evidence designed to survive the scrutiny of the reviewers who matter most.

Three ways we
can work together

01
Evidence Strategy & RWE Design
We architect real-world evidence studies using claims, EHR, and geospatial data — designed from day one to meet federal evidentiary bars, not just commercial payer standards.
02
AI/ML Audit & Equity Review
Independent evaluation of health AI tools against TRIPOD-AI, PROBAST, DECIDE-AI, and federal governance frameworks — with mandatory equity performance review across subpopulations.
03
Federal Market Entry Advisory
We position digital health products for CMS innovation models, Medicare coverage pathways, and federal contract vehicles — leveraging a decade of inside knowledge.

Indexed scholarship
as foundation,
not afterthought.

Calibrate Health's credibility is anchored in peer-reviewed research. Our principal scientist has published in JAMA, AJPH, and the Cochrane Database — and is actively contributing to the scholarly literature on AI governance and health equity in federal programs.

"Accurate for whom, validated against what standard, and defensible in front of which reviewer. That is what federal-grade evidence looks like."

Who we work with

✔  We work with
Digital health companies scaling toward CMS or payer market entry
Health systems evaluating AI vendor evidence before procurement

Organizations where equity is a design principle, not a checkbox
✘  Not the right fit if
You need a vanity audit that confirms what you already believe
Results are needed in 48 hours regardless of data quality
You treat health equity as branding rather than methodology
You want to outsource strategic thinking without collaboration
