AI can build software. It can't take responsibility for it.
We help startup founders and SMEs make sound technology decisions, build software and AI-enabled workflows that solve real business problems, and stay involved after launch. From a new SaaS product to a painful internal process, we start with the problem, not the tool.
Good technology starts with a clear problem
Too many projects begin with a tool, a trend, or a half-formed feature list. The result is often software that works technically but does not solve the thing the business actually needed.
A founder is left unsure what should be built next. An SME buys another tool and adds another manual step. A supplier delivers the scope and moves on.
We start by understanding the business problem, the people involved, and what a useful outcome looks like. Then we decide whether the answer is better software, automation, AI, an integration, or simply not building anything yet.
How we deliver technology
When we take responsibility for delivery, we work in four clear stages. You know what is being decided, what is being built, where human judgement sits, and what happens after launch.
1. Scope
We define the problem, the people affected, and what success needs to look like before anything gets built.
2. Build
We build the simplest reliable solution that fits the job, whether that is software, an integration, automation, or an AI-enabled workflow.
3. Control
For AI-driven, customer-facing, or commercially sensitive actions, we agree where a person needs to review or approve the outcome.
4. Run
We agree what happens after launch: handover, monitoring, support, improvements, and who owns what. No vague promises and no disappearing act.
What we help you build and improve
For a founder, that might mean getting a product from idea to launch. For an SME, it might mean replacing a messy spreadsheet, connecting existing systems, or fixing a workflow that wastes hours every week.
Bespoke Applications
Web applications built around your users, your workflows and how the business actually runs.
AI-enabled Workflows
Use AI where it genuinely helps: to remove repetitive work, speed up decisions, or handle information more efficiently, with sensible checks around the parts that matter.
Automation & Integrations
Connect the systems you already use so information moves where it should without someone copying, chasing, or checking it by hand.
Internal Operations Tools
Replace the spreadsheet, inbox, or workaround your team quietly depends on with software built around the way the business actually works.
SaaS Product Development
Take a product from idea to launch with clear scope, sensible technical choices, and a build that can keep evolving once real users arrive.
Technical Consulting
Get an independent view on what to build, what to leave alone, which vendors or tools make sense, and where the technical risks really are.
Our Packages
Fast answers, a plan before you build, or an ongoing partner. Start where you are.

Fractional CTO Retainer
from £2,000/mo
Monthly • Senior ownership of technology outcomes • Paid upfront
Senior technical ownership without hiring a full-time CTO. We decide what is worth building, lead the people and systems that deliver it, and stay accountable for whether it actually works.
- We own the roadmap: what gets built, what gets killed, and why
- Architecture and vendor decisions made, and stood behind
- Your developers or agency managed to a standard, with code review
- AI and automation introduced where it pays for itself, refused where it doesn't
- Defined monthly capacity and response times, agreed before we start
Most clients start with a Sprint, then move into the retainer for ongoing ownership.
