Our LLM Development Process

We follow a structured LLM development pipeline that covers the full model lifecycle, from use-case discovery to deployment. Each phase is delivered through Agile LLM sprints, with 6–8 week sprint-based delivery, Ireland-compliant data handling from day one, and feedback loops built into every sprint for transparent execution.

1. Use-Case Discovery & Planning

We begin by identifying viable use cases and mapping them to model capabilities. This step defines the LLM development pipeline, aligns data goals, and ensures all plans follow Ireland-compliant data handling from day one for safe, reliable delivery.

2. Client-In-The-Loop Prototyping

Each sprint uses client-in-the-loop prototyping for fast feedback and direction checks. We embed user validation into every cycle, creating feedback loops built into every sprint that reduce rework and increase model relevance.

3. Iterative Sprints & Testing

Our Agile LLM sprints deliver quick, tested iterations. Using a 6–8 week sprint-based delivery model, we develop features, validate logic, and ensure model behavior through transparent model testing and explainability in every round.

LLMs Built Around Your Business

From domain-specific training to model fine-tuning and optimisation, we adapt language models to understand your terminology, workflows and requirements while improving accuracy, consistency and performance.

FinTech

Training A Domain-Specific LLM For Financial Services

The Problem:

A financial services company wanted to use an LLM for customer support and internal advisory workflows, but generic models struggled with financial terminology, company policies and the organisation’s preferred response style. The business needed greater accuracy, consistency and control over model behaviour.

Our Solution:

We developed a domain-specific LLM training pipeline using curated financial datasets, company-approved content and example conversations. The model was fine-tuned to understand industry terminology and follow the organisation’s response standards, then evaluated against a dedicated test dataset before deployment.

The Result:

Improved accuracy across financial and domain-specific queries
More consistent responses aligned with company terminology
Reduced reliance on generic model behaviour
Established a repeatable framework for ongoing model evaluation

Professional Services

Fine-Tuning An LLM For Enterprise Knowledge

The Problem:

A professional services organisation wanted an AI assistant that could understand its internal terminology, document structures and specialised workflows. Generic LLMs provided useful answers but lacked the organisation-specific knowledge and consistency required for professional use.

Our Solution:

We fine-tuned an LLM using carefully curated internal datasets, example questions and approved responses. We created evaluation benchmarks to measure accuracy and consistency, then integrated the adapted model into the organisation's AI workflow with controlled access to business information.

The Result:

Improved understanding of organisation-specific terminology
More consistent responses across specialised workflows
Reduced manual effort for routine knowledge-based tasks
Created a structured evaluation process for future model updates

E-commerce & Retail

Optimising An LLM For Customer Support

The Problem:

An online retailer was using a general-purpose LLM to support customer service, but responses varied in tone and accuracy. The model struggled with product-specific questions, returns policies and order-related terminology, resulting in frequent human intervention.

Our Solution:

We fine-tuned the model using historical support conversations, product information and approved response examples. We evaluated the model against common customer scenarios, optimised its response behaviour and introduced guardrails for queries requiring human intervention.

The Result:

More consistent customer support responses
Improved handling of product and policy-related questions
Reduced repetitive workload for support teams
Increased the percentage of queries handled without manual intervention
