We build the software that OMOP CDM 5.4 pipelines, run on.
A software house. Our engineers embed with your team, build in your repositories, and hand everything over - code, pipelines, manifests - signed, and logged to a public transparency log you can check yourself.
We are a data software house
Sigil is a software company. We design, build and ship the tooling, pipelines and clinical software that turn healthcare data into evidence - as engineering, not as a service bureau. Studies and research are carried by our expertise hubs; what we build is the software they - and you - run on.
Eight tool families, around one spine. The estate is private, so you cannot count it from outside; under NDA we walk you through whichever family matters to you. Everything is handed over as repositories you own and can run yourself.
Signed, checkable handover
Every deliverable PDF carries a PAdES signature logged to the public Rekor transparency log. Verify it in your browser, no account needed.
Data that never has to move
Pipelines built to run where the data lives - EHRs, claims and registries harmonised to OMOP CDM 5.4 and HL7 FHIR R4 without extraction.
Forward-deployed engineers
Our engineers work inside your repositories, on your branches, to your review rules, until your team runs the stack without us.
Eight families, one spine
The software we build, grouped into eight tool families. The repositories are private; under NDA we walk you through whichever ones matter to you.
Toolchain & GitOps
Your whole software estate as declarative, auditable state - every org, every forge, one model.
Data Engineering · OMOP and FHIR
EHRs, claims and registries harmonised into OMOP CDM 5.4 and HL7 FHIR R4 - without moving the data.
Study-Package Tooling
Observational studies as declarative packages: authored once, executed identically against any site. The running of them is a hub activity; the tooling is ours.
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, shipped 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.
How we work with you
A software house, forward-deployed. We build in your repositories and hand over everything - and where the work needs domain depth, the right hub joins in.
Embed our engineers
Sigil engineers join your team in your repositories, on your branches, to your review rules - building your platform with you, not for you from a distance.
Build your platform
We stand up the toolchain, data layer and GitOps model your teams build on, and hand over the keys - repositories, manifests and docs.
Ship a study package
We build the pipeline and the analysis tooling for one study, as declarative packages. The study itself runs with the MTG hub or your researchers; you keep every repository that produced it.
Advise on standards
Architecture and interoperability guidance across OMOP CDM, HL7 FHIR, OHDSI and verifiable signing.
How we build
Read the problem
Requirements converge in open iteration cycles, in writing, before anything is built.
Model the data
Source schemas mapped to OMOP CDM 5.4 or HL7 FHIR R4, with the vocabulary decisions recorded as code.
Build in the open
Declarative pipelines, re-runnable from a clean checkout, reviewed in your repository - not in our heads.
Battle-test
Sandboxed runs against synthetic data and failure scenarios before anything touches production.
Sign and hand over
Deliverables signed with PAdES and logged to Rekor, then handed over as repositories you own.
From the hubs
Research carried by the expertise hubs, not by Sigil. These papers are MTG's and its collaborators'; we build the software such work runs on, and we say so precisely.
Novel Molecule design with POWGAN, a Policy-Optimized Wasserstein Generative Adversarial Networks
A policy-optimized Wasserstein GAN for de novo molecule design, extending reinforcement-learning-guided generative modelling. Preprint, not yet peer-reviewed. University of Porto.
MedGAN: optimized generative adversarial network with graph convolutional networks for novel molecule design
A generative adversarial network coupled with graph convolutional networks for de novo molecule design, demonstrating deep generative modelling for drug discovery.
Secur-e-Health Project: Towards Federated Learning for Smart Pediatric Care
A federated-learning architecture for smart paediatric care, training models across institutions while the data never leaves its source. MTG Research and Development Lab, with CINTESIS@RISE and GECAD.
Six people
Small by design, forward-deployed by default: a physician-founder, three software engineers, an operations lead and a strategic advisor. When an engagement needs domain depth, the matching hub adds its people to ours.

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 sit with the hubs; we would rather point at them precisely than borrow them.
The MTG hub 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.
Expertise hubs
Separate companies, each carrying domain depth Sigil does not claim as its own. When your engagement needs research, patient outcomes, value-based care, sovereign AI or zero-trust infrastructure, the matching hub pairs with our engineers; when it does not, we build without it.
Medipal
Personalised patient follow-up and patient-reported outcomes (PROMs).
Latest from the workbench
Dated, checkable entries - not a press release. The repositories are private; the verifier and the log are not.
The signature verifier is public
Anyone can check a signed PDF against its Rekor transparency-log entry, in their own browser. No account, and no record kept of what you check.
DARWIN EU network-model ETL cycle
lypto-darwineu, our ETL targeting the DARWIN EU network model, shipped its July maintenance cycle.
EHDEN network-model ETL cycle
lypto-ehden completed its June cycle against the EHDEN network model.

Tell us what you need built
A pipeline, a platform, a product. If you also need the study run, the MTG hub joins the engagement - say so and we will bring them.
