Trusted by organisations that cannot afford to get software wrong

What we do

Two services, two different starting points

Building something new and keeping something existing alive are different jobs, with different risks and different contracts. We run them as separate services.

New software

App and web app development

For organisations that need software built: a new product, a customer or internal portal, or a replacement for an application that no longer fits.

How it works

1Discovery: we work out what you need and what it should achieve.
2Scope and price: deliverables, milestones and payment stages agreed in writing.
3Build: delivered milestone by milestone, with a demo you sign off at each one.
4Launch: we take it live and, if you want, keep supporting it afterwards.

Typical projects

Customer portals and business platforms
Internal tools that replace spreadsheets and manual steps
Mobile apps for iOS and Android
Replacing an outdated application

Existing software

Support for existing software

For organisations that depend on software someone else built, and need a partner to keep it running, fix it when it breaks and keep it up to date.

How it works

1Assessment: we review the code, hosting and risks before you commit.
2Takeover plan: access, documentation and urgent fixes, in agreed order.
3Support plan: monitoring and maintenance, with incidents picked up 24/7.
4Ongoing: incidents handled and updates applied under the agreed plan.

FAQ

Common questions

Can you work on software another company or developer built?

Yes. That is what our support service is for. We start with an assessment of the code, hosting and documentation, so we both know what we are taking on before you sign a support agreement.

How do fixed-price development projects work?

We agree the scope, deliverables, milestones and payment schedule before development begins. The price covers that agreed scope. If you want something outside it, we estimate the change and only start once you approve it.

What if I am not ready to commit to a project or a support plan?

Start with a fixed-scope assessment, code review or AI Discovery. Each ends with a written result you keep, whether or not you continue with us.

Do you also build AI features?

Yes. AI agents, voice agents and AI-assisted search are part of what we build, as part of an app project or on their own. AI Discovery helps you find where AI is worth it before anything is built.
