01 / Challenge

Compliance onboarding was a chain of email attachments and manual review queues. Applications took nine days on average and a third were abandoned midway.

02 / Our approach

We modelled the entire onboarding journey as a state machine, then built a customer-facing application flow and an internal review console on top of the same engine.

03 / UX / UI

The applicant experience was reduced to five short steps with resumable progress. Reviewers received a dense, keyboard-driven console designed for hundreds of decisions per day.

04 / Technology architecture

A Go service orchestrates KYC providers, document storage and decisioning with full audit trails. Every state transition is immutable and replayable for regulators.

05 / Development

Built with contract-first APIs so web and internal tooling progressed in parallel, with load testing against three years of projected volume before launch.

Client testimonial

The audit trail alone paid for the project. Our regulator review went from a three-week exercise to an afternoon.
