We help UK businesses turn generative AI into practical, secure tools: AI assistants that answer from your own documents, automation that reads and summarises paperwork, content tools with your brand's guardrails, and AI features built into the software you already use.
- Proof of concept in weeks
- Built for UK GDPR
- Model-agnostic
- You own the solution
Generative AI that solves real business problems
Generative AI can draft, summarise, answer questions and extract information from documents in seconds. The challenge is making it accurate, secure and useful inside your business, rather than a demo that never reaches production.
We start with a specific problem, such as slow customer responses, time spent searching documents or manual data entry, and build the smallest AI solution that proves value. Then we connect it to your systems, test it against real questions and roll it out with the right safeguards.
Already using AI tools and want them inside your existing systems? See our AI integration services.

Generative AI development FAQs
What are generative AI development services?
Generative AI development services design, build and integrate AI that creates or works with content, such as text, summaries, answers, images and code. Typical projects include AI assistants, knowledge search over company documents, document processing, content generation and AI features inside existing apps.
How much does generative AI development cost in the UK?
As a guide, a proof of concept typically costs £8,000 to £25,000, a production AI feature or integration £25,000 to £80,000, and a custom generative AI platform £80,000 or more. You'll also pay ongoing model usage and hosting costs, which depend on how much the system is used. Prices exclude VAT.
How long does a generative AI project take?
A proof of concept usually takes 3 to 6 weeks, a production feature 2 to 4 months, and a larger platform 4 months or more, depending on data, integrations and testing.
Is our data safe when using generative AI?
It can be, with the right design. We use business or enterprise model services that don't train on your data by default, UK or EU hosting regions where available, access controls, encryption and logging, and we help you complete a data protection impact assessment where needed under UK GDPR.
Which AI models do you use?
We work with leading models from providers such as OpenAI, Anthropic, Google and Mistral, and open models such as Llama, often through Azure, AWS or Google Cloud. We choose based on accuracy, cost, speed and data requirements for your use case.
How do you stop generative AI giving wrong answers?
We ground answers in your own approved content using retrieval-augmented generation, test against real questions before launch, add guardrails and citations, and keep a human in the loop for important decisions. No AI is perfect, so we design for checking and monitoring.
Do we need to train our own model?
Usually not. Most business use cases work best with an existing model connected to your data. Fine-tuning or custom models make sense only for specialised tasks, high volumes or strict control requirements.
Can you add generative AI to our existing software?
Yes. We can add AI features to existing websites, apps, CRMs and internal systems through APIs, without rebuilding them. See our AI integration services.
