Technology. Automation. Growth.
Practical technology for ambitious businesses.
We design and build custom software, including systems that must not lose an order or a payment, and AI that takes repetitive work off your team, with people in control.

What we work on
Three areas of work that often meet.
Software needs to stay reliable as the business grows, an automation usually needs an integration, and a campaign needs a landing page and tracking that work. You can compare all five services on the Services page.
Custom Software & Systems Engineering
Web and mobile applications, B2B platforms, backend systems and payment integrations, for when standard tools stop fitting the way you work. We plan for failure from the first design.
AI & Business Automation
We map how a process runs today, then automate the parts that follow clear rules and connect the systems involved. Where AI drafts a reply, someone on your team decides whether to send it.
Digital Marketing & Growth
Google Ads, landing pages and analytics, starting with tracking that shows which enquiries each campaign brings in. Meta Ads too, if you use it.
Independent engineering review
Architecture & Reliability Audit for systems already in production.
You may be seeing events that go missing between services, payments recorded twice, timeouts that appear only under load, or two systems that disagree about the same order. An independent review shows which risks are serious and which to deal with first.
The audit ends with a written report your team can act on, and a session to go through it together. It identifies and prioritises risk; fixing what it finds is separate work, which your team can do, or we can.
Where systems fail
Retries, timeouts, queues and data that must stay consistent.
What to fix first
Risks rated by likelihood and impact, each with its evidence.
A plan you can use
A realistic roadmap, sized to your team's capacity.
How we work
Find out what is happening, then change what is worth changing.
- 01
Understand
We start with how things work today: the system, the process, or what your ad account records.
- 02
Plan
For larger work we suggest a scoped first step, such as an audit or a process assessment, before quoting for the whole project.
- 03
Build
Software is built in stages, with regular demonstrations of working software. New campaigns go live only after you approve them.
- 04
Support
After launch, we can monitor and support the automations we build.
