Data Engineering · Observational Research · Digital Health

Software and data engineering for science & healthcare.

A data and software house. We build the toolchain, the OMOP CDM 5.4 and HL7 FHIR R4 data pipelines and the clinical software that research groups and healthcare providers use to run observational studies - and we sign what we hand over so you can verify it.

Sigil
ABOUT

A data software house

Sigil builds the software, data and AI platform that research groups and healthcare providers use to turn clinical data into evidence. Foundational tooling, data engineering, clinical software and secure delivery - each stage reproducible, auditable and signed.

Eight tool families, listed below. The estate is private, so you cannot count it from outside; under NDA we walk you through the repositories behind whichever family matters to you. Everything we build is handed back as repositories you own and can run yourself.

Connected data network
PLATFORM

One toolchain, end to end

A cohesive platform that carries a study from raw data to a signed deliverable, grouped into the tool families our teams and partners build on. The repositories are private; we walk you through the relevant ones under NDA.

Toolchain & GitOps

Govern the entire software estate as declarative, auditable state across every org and forge.

Data Engineering · OMOP and FHIR

Harmonise EHRs, claims and registries into OMOP CDM 5.4 and HL7 FHIR R4 - without moving the data.

RWE Study Packages

Entire observational studies authored declaratively and executed the same way against any site.

Analytics Platform

OHDSI ATLAS, WebAPI and Achilles deployed as one project. A cohort-authoring assistant is in development.

Dashboards & Visualisation

Population and single-patient clinical views from the same spine - fail-closed, FHIR-native.

Vocabulary & Standards

Source-code to standard-concept mapping with national and local conformance, as overlays.

Signing & Compliance

PAdES PDF signatures, each logged to the public Sigstore Rekor transparency log. Every signed PDF carries a QR to its own log entry, and the verifier is open to anyone.

Agent Fleet & Automation

A governed fleet of headless agents running as CI gates with structured verdicts. A human authorises every merge.

ENGAGEMENT

Ways teams bring us in

Four ways teams bring us in: stand up a platform, run a study, embed engineers, or advise on standards. Everything we build is handed over as repositories you own.

Build your platform

We stand up the foundational toolchain, data layer and GitOps model your teams build on, then hand you the keys.

Run a study, end to end

Fixed-scope engagement. We take the protocol, build the pipeline and the analysis, and hand back the signed report plus every repository used to produce it.

Embed with your team

Our engineers work inside your repositories, on your branches, to your review rules.

Advisory & standards

Architecture, security and interoperability guidance across OMOP CDM, HL7 FHIR, OHDSI and verifiable signing.

PROCESS

Automated, self-testing and secure - by design

01

Deep requirements understanding

Fast, open iteration cycles converge requirements early and keep delivery transparent.

02

Automated by design

Every pipeline is declarative and re-runnable from a clean checkout. Human authorisation gates are explicit, not implicit.

03

Self-testing by design

Tested against synthetic datasets in sandboxed environments before anything touches production data.

04

Secure by design

Least-privilege access and secrets handled as references, never values - from the first commit.

05

Agent-assisted delivery

Headless agents run as CI gates and emit structured verdicts. A human authorises every merge.

06

Handover, not lock-in

You receive the repositories, the pipelines and the deployment manifests. Nothing runs only on our infrastructure.

STANDING

Where we stand in the OMOP ecosystem

Sigil is not an EHDEN-certified SME, not listed on the OHDSI Portugal national node, and not a DARWIN EU data partner. Those are held by organisations, and none of them is held by this one. What is on the record sits next door, and we would rather point at it precisely than borrow it.

Our research partner is on the register

MTG Research & Development Lab is a trained and certified EHDEN SME and is listed as an SME of the Portuguese OHDSI national node. That work is MTG's, not Sigil's.

Our founder built that practice

Tiago Taveira-Gomes founded MTG Research & Development Lab and was interviewed by EHDEN in 2023 on harmonising Portuguese data partners to the OMOP CDM. He brings that experience to Sigil; the certification stayed with MTG.

We build on the OHDSI stack

ATLAS, WebAPI and Achilles deployed as one project, with data landed in OMOP CDM 5.4, and ETL targeting the EHDEN and DARWIN EU network models. That describes our tools, not standing in those networks.

PARTNERS

Partners

Organisations we build with. MTG Research is our research partner and a certified EHDEN SME - the papers above are theirs, not ours.
