Clarity, control and traceability for high-stakes change

Lineage Advisory helps financial institutions deliver transformation across data, controls, and regulatory reporting. We focus on the structures that make systems trustworthy at scale: clear definitions, disciplined transformations, traceable lineage, and evidence that stands up to audit. The goal is simple: fewer breaks between Front Office, Operations, Finance and Risk—and fewer late surprises at close or submission.

What we do:

  • Deliver data platforms and operating models that preserve meaning end-to-end

  • Design controls, reconciliations and observability that turn noise into signal

  • Build audit-ready traceability for regulatory reporting and governance

  • Align front-to-back flows: trade → valuation → ledger → risk/reg outputs

  • Run migrations and remediation with dual-runs, equivalence tests and cutover criteria

  • Prototype, automate and productionise solutions into your chosen stack and tooling

How we work

We start with a short diagnostic to map flows, owners, breaks and definitions. We then design the target structure—entities, grains, control points and evidence—before delivering in increments with measurable outcomes. Documentation, runbooks and ownership are part of the delivery, not an afterthought.

Founder bio

Led by Stuart Simpson (FCMA, CGMA) — programme manager and data architect with 20+ years across banking, treasury, payments and regulatory delivery.

Writing & technical examples

He writes regularly on data lineage, financial semantics and regulatory architecture — focusing on how modern data platforms fail quietly in high-trust environments, and how meaning, ownership and control can be restored.
