A UK lender's loan-decisioning loop, rebuilt with dual-geo delivery.

London-based UK lender, ~£80M loan book. London-led FCA strategy. Manila-built decisioning agents. The case study no pure-UK and no pure-PH AI firm could deliver.

THE PROBLEM

36 hours to decide a £20k SME loan. Three competitors did it in 90 seconds.

The client is a UK-based specialist lender with an ~£80M loan book, focused on SME working-capital facilities. Underwriting was 60% manual: spreadsheet-based affordability, two underwriter reviews, manual risk scoring, manual document checks. Median application-to-decision latency was 36 hours. Conversion from approved-to-funded had been declining for six consecutive quarters because applicants who waited 36 hours had already accepted offers from challenger competitors who decided in 90 seconds.

The structural challenge: the client could not just "automate decisioning". Every model had to be FCA-auditable. Adverse decisions had to come with explainable reasoning. The data sources included Companies House feeds, Open Banking transaction histories, and proprietary repayment data — each with different residency and consent constraints.

WHY DUAL-GEO MATTERED HERE

A pure-UK firm would have been too expensive. A pure-PH firm would have failed the FCA review.

A pure-UK consultancy quoted £1.4M for the build alone, with no commitment on go-live date. A pure-PH offshore shop quoted £210k, but the lender's Compliance Director declined — the offshore team had no FCA-adjacent prior work and could not articulate what an SM&CR-aligned model card looked like.

Xamun's structure resolved both. Two London-based partners (one from financial services background) held FCA-side strategy, model governance and Compliance Director-facing artefacts. The Manila Software Factory held the engineering build. The dual-geo loop closed weekly between London and Manila — and the client's Compliance Director sat in on UK-side governance reviews every other Friday.

THE APPROACH

Five 21-day cycles. London ↔ Manila weekly.

XI · WEEK 0–2 · LONDON

Diagnose + FCA framing

XI mapped the existing decisioning workflow against FCA conduct-risk principles. Model governance framework drafted. Explainability requirements documented.

CYCLE 1 · MANILA

Data ingestion

Open Banking, Companies House and internal repayment data integrated. Data residency stayed UK-side (Azure UK South); engineering ran against synthetic mirrors in PH.

CYCLE 2 · MANILA

Affordability + risk model

Gradient-boosted affordability model + LLM-driven document parser. Every decision produced a structured reasoning trace and a model-card-aware audit log.

CYCLE 3 · MANILA

Underwriter copilot

For the ~22% of applications outside automated tolerance, a human-in-the-loop dashboard surfaced the AI's reasoning and let the underwriter override + record why.

CYCLE 4 · MANILA

Integration + shadow run

Decisioning agent ran in shadow mode for 3 weeks alongside the existing manual workflow. London team compared decisions; gaps reviewed weekly.

CYCLE 5 · LONDON-LED

FCA submission + go-live

Model documentation, governance pack and go-live signoff. PlayStudio dashboards live for Compliance Director on day one.

THE OUTCOMES

What actually moved.

DECISION LATENCY
36 hours → 11 minutes

Median application-to-decision. P95 stayed under 22 minutes including manual reviews.

CONVERSION
+18% app-to-fund

Conversion uplift attributable to decision speed. £14.4M incremental funded volume in Q1 post-launch.

RISK
In-band default rate

90-day default rate held within the lender's pre-set FCA tolerance band. No risk drift over the first 6 months.

FCA-AUDITABILITY
100% explainable

Every decision produces a structured reasoning trace. Compliance Director can audit any record end-to-end.

WHAT THIS COST

£196k total. Roughly 1/7 of the pure-UK quote.

Five 21-day cycles, a London-led XI Discovery, and a 6-week embed phase. Total contracted value: ~£196k. The pure-UK consultancy quote for the equivalent build was £1.4M with no go-live commitment. The pure-PH offshore quote was £210k but failed Compliance Director review. Xamun's £196k delivered the build AND the FCA-aware artefacts the Compliance Director needed to defend it.

Payback against the £14.4M incremental Q1 funded volume: weeks, not quarters.

UK regulated business. Offshore-shy. Talk to us anyway.
