Our work

Real outcomes for organisations that chose independence

We work under confidentiality, so these case studies are anonymised. The substance is real: owned, self-hosted systems delivered to organisations that decided not to depend on mainstream platforms.

Private banking/Ireland

An owned operations platform for a private bank

Replacing nine subscription tools with a single self-hosted system that models the bank's real workflows.

The challenge

The bank's middle office ran on nine separate SaaS tools that did not talk to each other. Staff reconciled data between them by hand, sensitive client records were spread across external services, and the annual subscription cost kept climbing.

Our approach

We mapped every operational flow over a structured discovery phase, then built a single platform around the bank's actual processes. We replaced the stack one function at a time, so operations never paused, and deployed entirely within the bank's own infrastructure.

The outcome

The bank now runs its middle office on one owned system, with every client record held inside its own perimeter and a complete audit trail of every action. Reconciliation that once took days is now continuous.

Logistics/the Gulf

Self-hosted analytics for a regional logistics group

A reporting system that keeps operational data inside the group's own environment.

The challenge

The group needed live operational analytics but could not send shipment and customer data to an external analytics platform under its data residency obligations.

Our approach

We built a self-hosted warehouse and pipeline that draws from the group's existing systems, and designed dashboards around the specific decisions its operations team makes daily. Nothing leaves the group's environment.

The outcome

Operations leaders now have live reporting on their own infrastructure, with full lineage and no data egress to third parties. The group owns the pipelines and can extend the models without external help.

Advisory/North Africa

A bespoke client portal for a boutique advisory firm

A branded portal that reflects the firm's character and keeps client documents in its own environment.

The challenge

The firm relied on a white-label portal that looked like everyone else's and stored sensitive client documents on a third-party service. It wanted an interface that reflected its institutional character and kept records in-house.

Our approach

We designed and built a portal around the precise set of actions the firm's clients need, integrated with the firm's identity system, and held all documents within the firm's own environment.

The outcome

The firm now presents a portal that carries its own brand and tone, with client documents held inside its perimeter and a self-service experience that has reduced routine support requests.
