LLM development company in the UK
Senior engineers on your morning and lunchtime hours, UK GDPR built in, and a fixed price before we start.
Clarigo Infotech is an LLM development company that builds custom applications on large language models such as OpenAI GPT, Anthropic Claude, Google Gemini and open-source models like Llama. We design the prompts, retrieval, tools and guardrails, connect the model to your data and systems, and run it in production with monitoring, evaluation and cost control.
UK businesses most often hire us for AI automation for service businesses, logistics software and fast MVPs for startups.

A written scope and quote after a free call, so the budget is settled before any work starts.
UK GDPR and data protection
UK or EU hosting, data processing agreements and privacy built into the design.
Weekly progress you can see
Working software every week and access to the code from day one.
Support after launch
The same team stays on with guaranteed response times, not a hand-off to strangers.
What we build with LLMs
Custom LLM applications
Assistants, copilots and internal tools built around your workflows, not a generic chat window.
LLM integration
Add GPT, Claude or Gemini to your existing product through secure, well-tested APIs.
Open-source and private models
Deploy Llama and other open models on your own cloud when data must stay in-house.
Fine-tuning and evaluation
Tune models on your examples and measure accuracy with test sets before and after launch.
Guardrails and safety
Input and output filtering, PII masking, grounding checks and human review where needed.
Cost and latency optimisation
Model routing, caching and prompt design that keep responses fast and bills predictable.
How we approach LLM development
Choosing the right model
There is no single best model. We compare OpenAI, Claude, Gemini and open-source options on your real tasks for accuracy, speed, cost and data handling, and design the app so the model can be swapped later without a rewrite.
Grounded in your data
Most business value comes from connecting the model to your documents, databases and tools. We use retrieval (RAG), function calling and agents so answers come from your information and actions happen in your systems.
Built for production, not demos
We add evaluation test sets, logging, monitoring, rate limits, fallbacks and cost alerts from day one, so the app keeps working well after launch and you can see exactly what it is doing.
Security and compliance
Data minimisation, encryption, access control and providers configured not to train on your data. For healthcare we build to HIPAA requirements with BAAs in place for any service that touches PHI.
How we work with UK clients
Time-zone overlap
UK and Indian working days overlap by around four to five hours every day, so your team is online for stand-ups, calls and quick decisions during your morning and early afternoon.
UK GDPR
We design products to UK GDPR principles: data minimisation, clear consent, access controls, encryption and data stored in the UK or EU when you need it. We sign NDAs and data processing agreements before work starts.
Billing
Invoices in British pounds (GBP) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Built for UK's key sectors
Financial services and fintech
London banks and challengers need secure, FCA-compliant digital products. AI here usually means faster reporting, fewer manual steps and better customer replies.
Professional services
Law and consulting firms automate document-heavy workflows. We start with one costly process and automate it end to end.
Retail and e-commerce
High online shopping adoption makes store performance decisive. We build AI agents, assistants and automation around these workflows.
Creative industries
Media and agencies adopt generative AI for content production. AI here usually means faster reporting, fewer manual steps and better customer replies.
