Services
Design and engineering, from one team.
We take a product from a rough idea to a live release and keep it running afterwards. Four services, usually combined.
- 01
Mobile apps
iOS and Android apps, designed, built and taken through store review to a live listing, then kept up to date.
- Native or cross-platform, chosen for the product and the budget
- Notifications, widgets, maps and location; accounts and payments where the product needs them
- Store submission, screenshots and listing copy
- Release management and updates as each OS version changes
- 02
Web platforms
Marketing sites, dashboards and web apps that load fast, are structured for search and cost little to run.
- Next.js and React, rendered ahead of time where it helps
- Content you can edit yourself, without a developer
- Technical SEO, structured data and Core Web Vitals as part of the build
- Designed and tested against WCAG 2.2 AA
- 03
AI & automation
Assistants, search and automation grounded in your own content, with citations a user can check.
- Retrieval over your documents, catalogue or knowledge base
- Responses grounded in approved sources, with citations where appropriate
- Evaluated against representative queries before release
- Fallbacks for when there is not enough evidence to answer confidently
- 04
Support & iteration
Monitoring, updates and new releases after launch, on a monthly arrangement with one month's notice.
- Uptime and error monitoring, checked by a person
- OS, framework and dependency updates before they become urgent
- An agreed block of development time each month
- Improvements planned from how people use the product
How it runs
Four stages,
each one you can see.
Whichever service it is, the work runs the same way, and every stage ends with something to look at or use.
- 01
Discover
Agree what to build, who it is for and what it will cost.
- 02
Design
Flows and screens, as a prototype you can try.
- 03
Build
Short iterations, each ending in a working build.
- 04
Launch & iterate
Release, monitoring and the updates that follow.
