Turning health data into
actionable intelligence

Founded in 2019, MD DataVault has grown from a specialist data curation consultancy into one of the UK’s most trusted medical data brokerage platforms — serving pharmaceutical companies, clinical research organisations, academic institutions, and health-tech innovators.

Why we exist

The UK generates some of the richest longitudinal health data in the world. NHS records spanning decades, primary care data from over 60 million registered patients, genomic biobank linkages, and real-world outcome registries. But that data remains largely inaccessible to the organisations that could use it most.

Regulatory barriers, fragmented governance, inconsistent coding, and siloed data systems mean that the journey from “we need data” to “we have data we can actually use” can take months — or fail entirely. MD DataVault was built to change that.

We act as the trusted intermediary: building the relationships with data controllers, investing in the compliance infrastructure, and delivering clean, properly documented datasets so your team can focus on the science, not the paperwork.

What sets us apart

De-identification & Anonymisation

Our multi-stage de-identification pipeline achieves k-anonymity thresholds appropriate to each use case, with full audit trails satisfying ICO and NHS IG requirements.
