The nervous system of your care
journey.
An architecture designed as a living organism: capture signals, model decisions, act with consent, secure every transmission. Palantir-inspired, redesigned for European healthcare.
Decision-first, not data-first. You at the centre — not your data.
Data, Logic, Action, Security.
Four interconnected dimensions running through the whole system. None is bolt-on: every one is woven into the architecture.
Data
A semantic layer, not a silo
Your health data unified through FHIR R4 (clinical) + OMOP (research). Whatever the source — lab, hospital, pharmacy, national health record — they speak one language.
Logic
Your rules, readable and auditable
Granular consents, sharing policies, predictive scores, orchestrations — all logic is explicit, modifiable, never a black box.
Action
You act, the system executes
Six patient verbs. Every action is a signed, traced, reversible event with cryptographic proof admissible in court.
Security
Security runs through everything
End-to-end encryption, key on your device, immutable consent ledger, verifiable audit trail. Not a layer added on top — a thread woven through every dimension.
Six actions. You, at the centre.
Most health platforms list features. We prefer to list what you can do.
Share
Granular access — by data, by professional, by duration. You choose exactly what Dr. Smith sees.
“I share my lab results with the cardiologist in Lyon, for 30 days, read-only.”
Revoke
One tap, and access stops. Revocation is recorded on the ledger — admissible even in court.
“I revoke access for the insurer I just left — instant effect, proof archived.”
Donate
Contribute to research on a specific condition. Anonymous donation, revocable, full control.
“I donate my diabetes data to the CNRS national registry — anonymised, revocable for life.”
Export
One click, and you get your passport in signed FHIR R4 format. Portable across Europe — no permission needed.
“I download my full record before a long trip to the United States.”
Bequeath
Designate the person who will inherit governance of your data in case of incapacity or death.
“I appoint my daughter as digital executor — multi-jurisdiction, European family law.”
Delegate
Hand management of your data to a relative or carer, with a precise, time-bound mandate.
“During my hospital stay, my partner can accept urgent shares — but cannot edit my history.”
A closed feedback loop, not an open tunnel.
Patient → Clinician → AI → Ledger → Patient. Every link feeds the next, every action is returned to the patient — readable, verifiable, revocable.
Patient
The patient emits a signal — symptom, measurement, sharing consent, donation to research.
Clinician
The professional receives the signal in context (FHIR), acts, prescribes, observes, returns a traced decision.
Predictive AI
AI analyses the trajectory, suggests alert thresholds, protocols, relevant research cohorts — always reviewable by a human.
Ledger
The HMAC ledger anchored to Bitcoin (OpenTimestamps) seals every consent, revocation, donation — immutable proof, admissible to patient and third parties.
This loop turns a static medical record into a living care journey. The patient is not the end of the chain — they are its centre.
No vendor lock-in. FR/EU stack, open-source.
We build exclusively on international standards and European or neutral open-source bricks. No dependency on a US or Asian vendor on the critical layer.
Open-source · TypeScript

Open-source · Vercel
Next.js + React 19
Modern React front-end framework. App Router, Server Components, native performance. Patient, doctor, admin, landing apps.
Open-source · PostgreSQL Global Group
PostgreSQL
Reference relational database, ACID, proven at scale. Stores our encrypted data + Prisma metadata.
Open-source · BSD
Redis
Cache + real-time pub/sub + BullMQ queues. Notifications, sessions, secure messaging throughput.
Hosting · France · HDS
OVHcloud HDS
Health-Data-Hosting (HDS) certified provider, sovereign French infrastructure, GDPR + Ségur compliant. No health data ever leaves the EU.
Standard · HL7 international
FHIR R4 + OMOP
Open multi-vendor interoperability models. Real portability guarantee to any HIS or research registry.
Every critical component is open-source or standardised. If needed, you (or we) can rebuild elsewhere without rewriting the business layer.
An architecture designed to put you in charge of your health.
