Products that make
Patient Histories Computable.
MedModels builds software for complex, longitudinal medical data - synthesis, harmonization, interoperability. Our flagship, the Patient Synthesizer, generates privacy-compliant synthetic cohorts inside your own environment.
Working with health insurers, hospitals, medical data owners and pharmaceutical companies.
The data we work with
A patient is a sequence, not a row.
One patient history is a chain of encounters. Each encounter carries its own coded diagnoses, procedures, and medications, and each of them is anchored in time. MedRecord keeps that structure intact — this is one anonymised example.

System Architecture
One foundation, many paths.
MedRecord is the shared substrate. Built on the open-source library GraphRecords, it defines how longitudinal medical data is stored and accessed — so every product above it speaks the same language. Hover a node to trace its path; select one to read more.

Why a shared record
MedRecord earns its place at the centre.
Longitudinal by design
Patient histories are stored as connected events over time — not flattened tables — so temporal structure is never lost.
Scalable and open
A Rust backend under a Python interface, built on the open-source GraphRecords library, with full code transparency.
One data model, every product
Synthesis, harmonization, and interoperability all read and write the same representation — no lossy hand-offs.
