Bespoke workflow and back-office systems, built for the way you work
When off-the-shelf does not fit, we build. End-to-end serverless systems on AWS: mobile-first, secure and scalable.

When off-the-shelf does not fit
Packaged software works until your process stops matching its assumptions. Then teams fill the gaps with spreadsheets, email and re-keying, and control and audit trails suffer.
We design and build systems around your actual process, from B2B incentive platforms processing thousands of claims to case management for regulated industries, on serverless AWS architecture that scales with demand and leaves no servers to manage.
What we build
Workflow and case management
Cases, tasks, approvals and escalations modelled on how your team really works, with every action recorded.
Claims and incentive platforms
B2B rewards and incentive schemes that take in, validate and process high volumes of claims.
Customer and partner portals
Mobile-first portals that let customers, partners and staff submit, track and act without phoning or emailing.
Document-centric processes
Systems with document capture and AI extraction built in, so information arrives as data. See document automation.
Integration and APIs
Connections to the systems you already run, so data moves once and stays consistent.
Reporting and audit
Dashboards and audit trails that show what happened, when and by whom, for operations and regulators alike.
How we build
Serverless on AWS
Lambda, Step Functions, Fargate and event-driven design: resilient, cost-efficient and nothing to patch. See serverless computing.
Security first
Least-privilege access, encryption and audit trails from day one, for regulated environments.
Supported after launch
We document what we build, train your people, and stay accountable for it with ongoing support and optimisation.

Frequently asked questions
When does bespoke software make more sense than an off-the-shelf product?
When your process is a source of advantage or regulation shapes it closely, when packaged products need heavy customisation, or when teams are already working around a product with spreadsheets and email.
Why build on serverless AWS?
Serverless systems scale automatically with demand, you pay only for what runs, and there are no servers to patch or maintain. That keeps running costs and operational overhead low as usage grows.
Do you support systems after launch?
Yes. Ongoing support and optimisation is part of how we work; our responsibility does not end at go-live.
How do we get started?
With a 30-minute discovery call, followed by a discovery and process assessment that maps your process, systems and constraints before we propose a design.
