Tell us what needs to work better.
You don’t need a finished specification. Bring us the product you want to build, the process that is slowing your team down, or the system you’re concerned about. We’ll help you understand the options and decide on a useful next step.
Talk it through with us
From the first decision to the next release.
- 01
Understand
We map the users, workflows and systems involved. Together we agree what matters, where the risks are and what to tackle first.
- 02
Build and improve
We deliver in small, reviewable steps. You can try the software, give feedback and see how decisions affect the scope and priorities.
- 03
Run and support
We agree how the application will be monitored, maintained and improved. Support is part of the conversation before launch, not an afterthought.

Insurance platform rebuild
Rubber Ring
Rubber Ring's digital insurance business had outgrown its original platform.
Discover how we rebuilt it on a modern, event-sourced architecture on AWS - a single-table DynamoDB source of truth streamed into a PostgreSQL read model, with containerised React Router 7 and PHP applications on ECS Fargate - and migrated the entire live book in one cutover.
Duwio
Working with Spacesuit Media, we transformed years of experience in image delivery into Duwio - a new SaaS platform for creative professionals, re-engineered from the ground up on AWS.
Built on an AWS well-architected foundation, it enables photographers and agencies to store, tag, search and deliver images seamlessly from anywhere in the world.

The detail behind dependable software.
Security, recovery, running costs and ease of change need attention throughout an application’s life. Our Cloud Excellence Framework gives those decisions a shared structure.
Explore the framework
Web application development
Whether your web application is the product your customers pay for or the system your team works in every day, it has to be fast, secure, and safe to change for years after launch.
API development
Whether an API is the product you sell or the plumbing that keeps your operation moving, it needs to be fast and secure, and safe for your team to change.
Cloud hosting and infrastructure
Business operations software has to be there every time your team opens it. We design the AWS infrastructure underneath it, keep it secure and current, and stay on to watch it long after launch.
Serverless application development
SaaS platform development lives or dies on what happens under load. Serverless applications on AWS scale with the customers using them and cost almost nothing when they are idle, so growth becomes a feature of the architecture rather than a bill you dread.
Legacy application migration and modernisation
Old software that still earns its keep does not need throwing away. We modernise legacy web applications and move them to AWS in careful steps, so the business keeps running while the code underneath it gets better.
Web application support and maintenance
Software does not look after itself. We support and maintain the web applications businesses run on, keeping them patched, monitored and improving, as the same small team that built them and for as long as they are needed.
Security and data privacy
Security is a way of building software rather than a pass you make over it at the end. We design it in, from authentication and encryption to the data protection duties you carry under UK GDPR, and keep it current for as long as we run the system.
User interface and user experience design
A design is only as good as what people can actually do with it. We research the work, prototype the flows, test them with the people who will use the software, and then build what we designed, so the version that ships is the version that was tried.
PHP and Yii development
You already own a working PHP or Yii application. We keep it secure and current, and we tell you honestly whether it is worth maintaining, modernising, migrating or leaving well alone.
SaaS application and digital product development
We build SaaS platforms and digital products with the people who will run them, from the first working version through multi-tenancy, billing and scale. It runs in your own AWS account, and you are never locked in.
Mobile app development
Whether it is a product people download or a tool your team uses on site, a mobile app has to feel native, keep working when the signal drops, and survive the next OS update.
