Custom GenAI Development
Purpose-built and state-of-the-art generative artificial intelligence (GenAI) solutions to drive growth and innovation.
Design a private, custom-built AI environment
Generative AI (GenAI) tools and platforms are built using large language models (LLMs). This enables them to generate human language. Several well-known GenAI tools are proving highly effective in driving operational efficiency, by automating processes, enhancing decision-making and unlocking new value streams. However, these tools are not typically hosted in a private environment, so sensitive business information could become public.
NashTech custom GenAI development services use LLMs to create a private AI environment tailored to the specific needs of our clients and the use cases that deliver the highest business impact for their organisation. We use advanced technologies including LLMs supported by Retrieval Augmented Generation (RAG), application programming interfaces (APIs), Robotic Process Automation (RPA) and others, to unlock the full potential of GenAI and the vast volume of business data generated by your organisation.
We have also developed a Generative AI Accelerator, which cuts the development time and costs associated with GenAI projects significantly. It can be applied in any industry sector and customised to your use case and goals.
Overcome the barriers to GenAI adoption
Generative AI is a specialist and constantly evolving technology, so many organisations do not have the in-house expertise or resources to test and adopt it.
Developing a solution tailored to an organisation’s specific needs often requires integration with existing systems, which involves multiple technologies and, consequently, a diverse skill set.
Many companies struggle to justify the business case for GenAI solutions due to the difficulty of demonstrating return on investment (ROI).
GenAI is a new and powerful technology, therefore many businesses struggle to realise the range of ways it can be applied or understand and articulate its possibilities and limitations.
Using publicly accessible GenAI solutions and sharing company-specific information can pose significant risks, including potential data breaches.
Deliver the biggest business impact with custom GenAI solutions built for your business needs
Our dedicated generative AI research and development team ensures we keep ahead of technology trends and any updates are tested thoroughly before being rolled out.
Our GenAI team includes architects, developers and professionals skilled in programming languages, as well as consultants and business analysts that align a solution with your strategic goals.
Identify, quantify and demonstrate the business value of your new AI solution with our team helping you to define the appropriate success metrics.
We can create custom demonstrations using our Generative AI Accelerator to visualise the value our GenAI solutions can create for your business so your stakeholders understand its full potential.
A custom-built GenAI solution is privately hosted on your infrastructure, so it is secure by design. NashTech is ISO27001 accredited and apply additional security measures such as encryption and access control.

Case study: Classifying tax notices with document AI
of tax notices
and errors
accuracy achieved for data extraction

Ultimate Kronos Group (UKG) is a provider of workforce management and human resource management services. It was struggling to manage and classify the 400 different types of tax notices being processed and needed an approach like Jaccard Similarity, which identifies differences and similarities between samples. UKG partnered with NashTech and built an automated system using Document AI services, Google Document API and Data Loss Prevention (DLP) so that the data could be mapped and optimised.
Case study: Using AI to predict the likelihood of insurance renewals
customer churn
renewal rates and profitability

This UK insurance company partnered with NashTech to develop a custom tool that predicts the likelihood of customers likely to churn when their policy expires. The predictive tool is based on SageMaker and enables the insurance provider to personalise renewal prices and create targeted retention strategies. By taking a data-driven approach, the business can enhance customer retention and profitability.
Case study: Personalising customer communications at scale
in manual input
in relevance and tone across email types

This marketing business partnered with NashTech to deploy an AI-powered tool that generates high-quality, relevant emails to help it offer personalised communication and maintain its brand voice. It used the retrieval-augmented generation method, advanced LLMs and prompt control tone, style and structure. The client is now able to generate personalised emails to engage its target audience, while boosting engagement and relevancy.
Frequently asked questions
NashTech’s specialist team examines your business processes to identify any challenges or areas where generative AI can make an impact, as well as the data or integrations needed. Next, our team will put together a roadmap including the architecture and delivery plan with realistic timelines. Our team manages the build including development and testing, while also offering ongoing implementation support to ensure the solution works for you.
Our generative AI accelerator is built with Microsoft services including Azure AI services, Azure AI Search, Azure OpenAI Service and more. It is deployed on Microsoft Cloud. However, the solution is platform agnostic, so it can be built using other cloud providers. Primary knowledge is obtained from the OpenAI GPT model, but it can be tailored with your business information such as policies or training.
Generative AI is a powerful technology and its use cases seem endless. We often discuss use cases such as product integration, customer service automation, data analysis, content generation, personalised assistants, call transcript analysis, website chatbots and more.
Pre-built models are not customised using your business information such as training documents or policies – and they don’t keep your private information secure. A custom solution enables you to use LLMs, while ensuring your data is kept private.
A custom GenAI development solution does not need to be expensive. Start small with high-impact use cases such as content generation or transcript analysis and develop a minimum viable product that proves its value. Our generative AI accelerator helps to cut costs associated with development and its architecture is scalable, which eliminates the need for larger investments in infrastructure.
