Case Study

Turning compliance from a cost centre into a data product.

March 2026 · Banking & Fintech
Overview

A regional bank was reviewing 40,000 documents a month by hand across three product lines. We built a document intelligence layer that reads, classifies, and escalates — cutting review load by 38% without adding headcount.

01 · Context

The situation on arrival.

Compliance headcount had grown 4× in three years while transaction volume grew 11×. Every new product launch required a linear increase in reviewers, making the unit economics of growth progressively worse.

Regulators had also flagged inconsistency between reviewers as an emerging concern — different analysts were reaching different conclusions on structurally similar files.

02 · Approach

How we structured the work.

We began with a two-week readiness assessment covering data quality, document taxonomy, and reviewer decision patterns. Rather than automating the review outright, we designed a triage architecture: the model handles classification and routing, humans retain all adjudication authority.

This kept the bank comfortably inside its regulatory perimeter while removing the highest-volume, lowest-judgement work from senior desks.

The goal was never to remove the human from compliance. It was to stop spending senior judgement on document sorting.
03 · What we built

Systems now in production.

  • A RAG-based document classification pipeline over the bank's existing document store.
  • A confidence-scored routing engine that escalates ambiguous cases to senior reviewers.
  • An audit trail capturing every model decision and human override, plus a governance dashboard for the compliance committee.
04 · Outcome

What changed for the client.

Manual review load fell 38% within two quarters. Reviewer-to-reviewer consistency improved measurably.

The bank launched its next product line without adding compliance headcount for the first time in its history.
