An underwriting engine, rebuilt
An unsupported underwriting engine rebuilt into a live, audited platform. The business-critical logic was carried across, then run and supported by the team that wrote it.
How we modernise legacy systemsbuild
Software built around the work your business needs to do.
Custom applications, legacy modernisation, integrations and governed AI. One team from discovery through deployment and support, with UK-hosted options and clear ownership.

How we modernise legacy systemsWe have built AI inference that runs entirely in the United Kingdom for a client. UK-hosted deployment is available. Where a project uses a third-party model provider, we name it and document the data flow before implementation.
How we scope hosting and data flowsAinsley answers questions about DSC and can pass an enquiry to our team. We built the assistant with a kill switch and a logged record of exchanges. It calls a third-party model provider; it is not our example of UK-only processing.
We start with the process and the system you need. That may call for a custom application, an integration or a legacy rebuild. Automation and AI fit where they serve that work.
We design AI systems with approval gates, bounded actions and auditable records. Data flows, model providers, storage locations, retention and subprocessors are documented before implementation.
Web applications, internal tools and APIs; existing platforms modernised while preserving the business logic you rely on. Build is our software discipline. Routine IT changes sit within managed IT.
Applications built around how your business works, including legacy systems rebuilt without losing the hard won logic you depend on, engineered with security in from the first line of code. Our main line of work, and what everything else here plugs into.
Explore custom softwareAI put to work where it earns its place, with approval gates, bounded actions, a kill switch and auditable records, so a person stays in charge of what it may do.
Explore applied AIThe repetitive manual work that takes up your team's week, automated and made reliable, with approval gates and a full audit trail so it stays under control.
Explore workflow automationThe tools you already run, made to work as one, so data flows correctly and your people stop bridging the gaps by hand.
Explore systems integrationWebsites, online stores and web platforms built secure and fast, with SEO and AI-search visibility designed in, hosted and looked after by the team that also runs your IT.
Explore web development30 seconds · Silent explainer. Custom software, automation and integrations.
We review the work your people need to do and the systems involved. Then we design the application, integration or automation around that process.
You see working software during the project. Security, permissions, testing and deployment are part of the work. Where AI is used, its actions and approval gates are agreed.
The team that builds the software can also host, maintain and support it.
Still copying the same data between systems?
We build software, integrations and automation around the way you work. It's scoped separately from managed IT.
First, agree the data, access and what happens when something goes wrong.
Then test the normal flow and the exceptions. Document it, and check the agreed acceptance criteria before handover.
Dead Simple Computing. Tell us where the work gets stuck.
Understand the process, existing business logic, users, dependencies and the result the software must achieve.
Agree the architecture, security, hosting and any AI controls. Approve the scope and plan before implementation.
Review working software early, test the business logic and integrations, and check permissions and audit trails.
Plan the release and handover, with hosting, maintenance and support responsibilities agreed.
We run and secure technology as well as writing software. That informs the way we design a web application, internal tool, API or legacy replacement.
The project includes the decisions needed after launch: hosting, access, monitoring, maintenance and the person responsible when something needs attention.
Bring the process worth automating, the system you need or the legacy platform that needs attention. We will discuss the work, its dependencies and a sensible first scope.
Monday to Friday, 9am to 5.30pm.
