AI, without the hype

AI Development That Delivers Business Value

We build AI agents and integrate AI into business software where there is a clear use case. We also use AI-assisted tools in development, with experienced engineers reviewing the work. The aim is useful automation, not AI for its own sake.

Where AI Pays Off

  • Repetitive work: sorting enquiries, processing documents and updating records.
  • Knowledge search: finding answers across approved company documents and policies.
  • First drafts: preparing summaries, reports and responses for human review.
  • Software delivery: AI-assisted coding and testing, reviewed by engineers.

Where It Needs Care

  • Accuracy: AI can produce incorrect answers and needs suitable checks.
  • Data privacy: what is shared with providers, where it is processed and UK GDPR.
  • Running costs: model usage and infrastructure expenses can rise with demand.
  • Provider dependence: model capabilities, pricing and terms can change.

How We Handle It

  • Human approval for consequential actions and customer-facing decisions.
  • Testing against representative business scenarios before release.
  • Appropriate access controls and clear data-processing arrangements.
  • Architecture and usage monitoring designed to retain practical flexibility.

FAQ

Questions UK Clients Ask First

Didn’t find yours? Ask us directly and we’ll discuss the technical and commercial details.

How much does custom software or AI development cost?

Costs depend on the scope, integrations, security requirements, team and delivery model. A focused AI pilot, MVP and complex platform require different levels of work. We review your requirements before proposing an estimate or team rate.

Can you build AI agents and integrate AI into existing software?

Yes. We develop AI agents, LLM integrations, retrieval-based knowledge search and workflow automation for existing applications. Feasibility depends on your systems, APIs, data access and the actions the solution needs to perform.

Will the team work in UK hours?

We agree the required overlap with UK working hours during project planning, including meetings, sprint reviews and communication expectations.

Who owns the code and intellectual property?

Source-code ownership, IP transfer, repository access and handover arrangements are set out in the contract before work begins.

How quickly can you start?

The start date depends on the scope, specialist skills and team availability. After the initial discussion, we can confirm a realistic mobilisation and delivery plan.

Do you sign NDAs and consider UK GDPR?

We can discuss an NDA before receiving confidential information. For relevant projects, we assess data flows, access permissions, provider arrangements and applicable UK GDPR obligations.

Do we actually need AI, or would automation work better?

Not always. Rule-based automation can be simpler and more predictable for structured tasks. AI is useful when work involves unstructured documents, natural language or information retrieval. We recommend the approach that fits the process.

Is our data safe if we use AI?

AI data protection depends on the architecture and providers selected. We assess what data is processed, where it goes, who can access it and whether human approval or additional safeguards are needed. No AI system should be described as risk-free.
