AI-powered healthcare data platform

Your digital twin.
Always yours.

Upload your medical documents. HealthTwin turns them into one unified, validated health record — structured to the clinical standard, owned by you.

Conservative by design — never invents clinical data
The problem

Built to be stored. Not to reach you.

Your history is real. It's just scattered across hospitals, labs, and portals that were never designed to hand it back to you — as loose PDFs, printouts, and logins you don't remember.

Confirmed across 40+ interviews with patients and physicians
How it works

From loose document to living record, in three steps.

No endless forms. Upload what you already have — HealthTwin does the structuring.

1

You upload a document

A lab PDF, a photo of a printed result, an imaging report — whatever you have on hand.

2

It gets structured and validated

Specialized agents extract the data, map it to the FHIR clinical standard, and validate every result before it's stored.

3

Your record, always on hand

A clear, longitudinal view of your health — ready to understand, compare, and share whenever you decide.

Why now

The law already opened the door. Almost no one walks through it.

Two things are converging: the right to your records exists today, and the cost of turning those records into structured data just collapsed.

In effect today

You already have the legal key

Under HIPAA's Right of Access, any U.S. provider or health plan must give you a copy of your records within 30 days, in the format you ask for, for a limited fee.

45 CFR § 164.524
January 2027

Payers are forced to open up

CMS-0057-F requires impacted payers to expose patient data through FHIR R4 APIs — turning a manual request into a direct connection.

CMS-0057-F Final Rule
Where it lands

HealthTwin is the destination

We're building the place all that newly freed data arrives — structured, validated, and owned by the patient rather than by whoever generated it.

Patient-owned by design
Security and trust

Conservative by design.

We don't treat your medical history as text to be summarized. Every value passes validation before it becomes part of your record.

Never invents clinical dataIf a value can't be validated with certainty, it isn't stored.
Traceable to the sourceEvery value keeps its link back to the original document.
You decide what gets sharedNothing leaves your account without your explicit authorization.

Built on clinical data standards

FHIR R4 HL7 Encrypted

HealthTwin structures your information in FHIR R4 — the clinical interoperability standard U.S. regulation will require payers to support starting in 2027. Your record is genuinely yours, and it works with any system that needs it.

HealthTwin is not a medical device, and our handling of health data goes beyond what HIPAA legally requires — we voluntarily apply HIPAA-level security safeguards and design our privacy practices to the higher standard set by GDPR.

In one line

HealthTwin is an AI-powered healthcare data platform.

Which is the long way of saying: every document you've ever been handed becomes one record — read by AI, checked against the clinical standard, and owned by you instead of by whoever printed it.

What you can do with it

One record. Everything it makes possible.

Not another portal to log into. The one place your history actually belongs to you.

See what changed

Compare results across years, not appointments. Trends you'd never spot in separate PDFs become obvious in one timeline.

Share on your terms

A clean, structured summary ready for any doctor — without digging through folders or forwarding a dozen attachments.

Arrive prepared

Walk into any visit with your full history, instead of reconstructing it from memory while someone waits.

Keep it when things change

Switch doctors, insurers, or countries. Your record doesn't live in their system — it lives in yours.

Plans

Start free. Grow when you need to.

Your core health record stays protected, even if you never pay a cent.

Where we are

Built in four months. Running, not rendered.

An AI-native company building clinical infrastructure. We'd rather show you the state of the system than describe it.

System and traction status

Updated continuously
Clinical pipeline
Hermes, our multi-agent orchestrator, runs every document end to end: classification, image-quality check, extraction, FHIR R4 mapping, validation, timeline construction, and alert detection — with gates between each stage.
Live
Validation gate
Before any finding becomes a FHIR resource it passes semantic validation — filtering negations and uncertainty — then a structural gate. If it doesn't validate, it isn't stored.
Live
AI layer
Hybrid by design: cloud models on Azure AI Foundry handle clinical orchestration, while a local model on our own infrastructure handles in-app chat and sensitive tasks — sensitive data doesn't have to leave our environment.
Live
Infrastructure
Deployed on Microsoft Azure, with Azure Health Data Services as our standards-compliant FHIR R4 repository. Row-level security at the database, token-based doctor access with expiration and revocation.
Live
Engineering
AI-native from day one. One technical co-founder, working with AI-assisted development, ships at the pace of a much larger team. Every line of product code is written in-house — no outside contractors, no licensing entanglements.
By design
Early cohort
First users onboarded and actively building their unified timelines. We're opening access gradually as we harden the flow.
Onboarding
Problem research
40+ interviews with patients, physicians, and domain experts confirmed that manual record retrieval is broken.
Validated
Next milestone
Broader validation with a larger cohort — measuring retention and how much users would miss HealthTwin if it disappeared.
