Custom software development

Off-the-shelf software makes your business fit its assumptions. We build platforms, internal tools, and SaaS products around how you actually work.

What this includes

Greenfield product builds

New platforms and SaaS products taken from an unclear problem through architecture, build, and launch.

Internal tools and operations software

The systems that replace a spreadsheet held together by one person’s memory, rebuilt with real permissions, audit trails, and reporting.

Legacy modernisation

Incremental replacement of systems that still work but cost too much to change. We migrate without a big-bang rewrite.

APIs and integrations

Connecting the tools you already pay for, so data stops being copied between systems by hand.

Four things that exist when we are done.

  1. A documented architecture you can hand to any engineer

  2. Production deployment with monitoring and alerting

  3. Source code and infrastructure you own outright

  4. Weekly demos against a scope you can hold us to

Financial Compliance / RegTech

Audit prep time reduced by 70%

A real-time compliance monitoring platform built to replace a fragmented spreadsheet-and-email workflow, automating regulatory reporting across 12 jurisdictions and flagging anomalies before they become violations.

Questions we get asked

Ask us something else

Cost tracks scope and risk, not headcount. A focused internal tool is a different order of magnitude from a multi-tenant platform with compliance requirements. We scope in discovery and give a fixed range before any build starts, so you are deciding with real numbers rather than a placeholder.

Most projects reach a usable first release in two to four months, with the first working software in weeks rather than at the end. We run design and engineering in parallel and demo weekly, so progress is visible throughout instead of arriving as one delivery.

Yes. Source code, infrastructure definitions, and documentation are yours. We do not build on a proprietary platform that makes leaving expensive, and we hand over in a state another team could pick up.

We support the launch, monitor production, and continue development as your needs change. Handing over a repository and disappearing is how systems rot. The studio stays engaged unless you would rather take it in-house, in which case we document for that.
