Rebuilding a Digital Bank's Technology Cost Base

Consolidating three engineering hubs into one and renegotiating top vendor deals cut a digital bank's technology cost per customer by roughly a third.

01 The Problem

The operating constraint behind the numbers

The digital subsidiary of a regional bank scaled customers rapidly while technology costs scaled faster. Engineering teams were fragmented across three locations, platforms inherited from the parent duplicated each other, and the largest vendor contracts had been signed in a hurry during launch.

03 The Kingswell Response

What changed in the management system

Consolidate engineering into one hub

The three engineering locations were consolidated into one hub with a defined capability charter.

Rationalise overlapping platforms

Overlapping platforms inherited from the parent were rationalised onto a target architecture.

Introduce AI assisted development tooling

AI assisted development tooling was introduced to lift engineering productivity.

Renegotiate largest vendor agreements

The five largest vendor agreements were renegotiated from a position of consolidated demand.

04 What Remained

The management system installed

Consolidated engineering hub with a defined capability charter

Target architecture for rationalised platforms

AI assisted development tooling

05 The Result

What the organisation could do next

A technology cost and architecture diagnostic set the fact base. The three engineering locations were consolidated into one hub with a defined capability charter, overlapping platforms were rationalised onto a target architecture, AI assisted development tooling was introduced to lift engineering productivity, and the five largest vendor agreements were renegotiated from a position of consolidated demand. Technology cost per active customer fell by roughly a third within a year while release frequency improved, and the hub model became the parent bank's template for two later ventures.
