How a regulated EU financial services firm cut KYC onboarding from 5 days to 1.2 — without an EU AI Act audit headache

A regulated EU mid-market financial services firm — around 400 employees, serving SME and retail clients across multiple member states — engaged Arqmetrica for a 90-Day AI Value Sprint to identify, prototype, and ship a single ROI-positive AI use case under documented EU AI Act controls.

At a glance

Industry: Regulated financial services
Company size: ~400 employees · multi-country EU operations
Engagement type: 90-Day AI Value Sprint — diagnose, prototype, deploy
Headline outcome: KYC onboarding cycle time cut 76% with audit-ready EU AI Act documentation from day 1

By the numbers

What the engagement produced

76%: reduction in median time-to-onboard
4 FTE: ops capacity reallocated to higher-value review
0.9%: final error rate (vs 3.2% baseline)
€480k: annualised value vs €90k engagement cost

The challenge

Customer onboarding was a known bottleneck. KYC document review took roughly five working days per new client, required six to eight ops staff, and produced a 12% drop-off rate during onboarding. Multiple AI vendor pitches over the previous eighteen months had stalled at the same wall: none could clearly answer where their solution sat under EU AI Act risk classifications, the compliance team rejected vendor-led pilots that didn't include documented human oversight, and there was no internal framework for evaluating ROI against regulatory risk in parallel.

What we built together

Deliverable 1
Use case prioritisation against EU AI Act classification
Diagnosed twelve candidate AI use cases across operations and compliance. Each scored against feasibility, ROI, and EU AI Act risk classification. KYC document review emerged as the priority: high-volume, well-bounded, limited-risk under Article 6.
Deliverable 2
Production-grade prototype with audit trail built in
A vendor-neutral pipeline combining the firm's existing document management system with a GenAI extraction layer. Article 14 human-oversight checkpoints built in from day 1; Article 11 technical documentation maintained throughout; full audit trail. No proprietary lock-in.
Deliverable 3
4-week shadow deployment, then phased production rollout
Ran AI extraction in shadow mode (humans still reviewed everything) for four weeks to calibrate confidence thresholds against the firm's actual risk appetite. Production rollout configured human-in-the-loop for any extraction with confidence below 92% — measured, defensible, audit-ready.

The outcome

The Value Sprint left the firm with a calibrated production system, a defensible governance posture (already audit-ready under EU AI Act), and a documented framework they're now applying to two further candidate use cases without us. The Arqmetrica engagement ended at 90 days; the capability stayed.

What leadership said

“We had been told for two years that AI would solve our KYC bottleneck. The pilots that came before always died at the compliance gate. This was the first that didn't.”
