Synthetic healthcare data · Medicare Advantage available now

The data that lets healthcare build — without waiting on PHI.

Verism Health builds synthetic patients — then renders their entire data trail. Claims, eligibility, encounters, labs, quality measures, revenue — across every line of business, all from the same AI-generated archetypes. Real data takes months and six figures to license. Ours downloads in a minute, with no privacy review.

The problem

Everyone in healthcare needs data. Almost no one can get it.

To build a risk model, benchmark a population, validate a measure, or demo a product, you need realistic healthcare data. But the real thing is buried under HIPAA, DUAs, and licenses that cost $50k–$250k a year and take months of legal review to touch.

So consultants can't benchmark, startups can't prototype, and data teams can't test until a deal closes. The data exists. The friction is the product we're replacing.

Synthetic data removes the friction — ifyou can trust it matches reality. That's the bar we hold ourselves to.

The archetype engine

One synthetic population. Every record renders from it.

We don't generate disconnected tables. We generate synthetic people — archetypes — with full clinical lives, then render whatever data domain you need from that single coherent source. The same diabetic member produces the claim, the lab, the gap, and the revenue — and they all agree.

1

Generate people

AI builds a library of clinically-coherent patient archetypes — conditions, comorbidities, demographics — grounded in real-world clinical knowledge and published prevalence.

2

Generate journeys

Each member lives out time: enrollment, condition progression, acute episodes, care patterns, and persistence. A diabetic with CHF looks like one — month over month.

3

Render any domain

Those journeys emit whatever you need — claims, eligibility, encounters, labs, quality measures, revenue — for whatever line of business. One source of truth, every record consistent.

One engine, every render target

The data domains the archetypes produce.

Everything joins on member_id. Take the domains you need today — more render from the same people as we expand.

Full product details →

Eligibility & enrollment

Available now

Member-month enrollment, demographics, plan/program, and benefit status — the spine every other domain links to.

Medical claims

Available now

Line-level institutional + professional claims: diagnoses, procedures, settings, allowed/paid, and realistic adjustment chains.

Pharmacy

Available now

NCPDP-grade drug fills with refill chains, benefit phases, formulary tiers, and net-of-rebate economics.

Revenue & payment

Available now

Payer-side revenue the way a plan receives it — capitation, risk scores, and the factors behind every dollar.

Encounters

Expanding

Encounter-level utilization independent of billing — the visit-and-service record health systems and value-based programs run on.

Labs & results

Expanding

Ordered tests with realistic result values trended to each member's conditions — A1c that tracks the diabetic, eGFR that tracks the CKD.

Quality measures

Expanding

Measure-ready numerators, denominators, and gaps (HEDIS-style / Stars) rendered from each member's actual care.

Why you can trust it

We treat fidelity like an eval — and publish the score.

Synthetic data is only worth buying if it matches reality. Every release ships with a credibility audit comparing dozens of metrics against published benchmarks — with citations. If a number drifts, you see it.

Releases, like models

Each version is a better model of reality.

Like language models, our datasets improve with every release. Newer versions model more of the messy truth; older ones are cheaper and lighter. Pick the fidelity your use case needs.

Who it's for

Built for the people blocked by data access.

Consulting & actuarial

Benchmark without a license

Stand up benchmarks, test methodologies, and prep client work without a six-figure data deal you can't expense to a prospect.

Health tech

Build before the data deal closes

Develop and demo on realistic data with zero PHI exposure. Ship the product, then swap in the customer's real data later.

Data science

Train, validate, backtest

A labeled, controllable, reproducible dataset for risk models and pipelines — with the ground truth you never get from real data.
