Bespoke AI Solutions Built Around Your Business
When off-the-shelf tools are not enough, Hartz AI designs and builds bespoke AI solutions that fit your workflows, data, and teams. Private GPTs, custom AI tools, automation systems and more, created specifically for how your organisation works.
Can we build a custom AI solution specifically for your business? Yes, when a custom build is the right answer. We first check whether an existing tool would do the job, and only build when it would not.
A bespoke AI solution is an AI system designed and built for one organisation's workflows, data and rules rather than bought off the shelf. Hartz AI builds them for UK businesses with your team: private assistants, workflow automation and insight tools, delivered with training and governance so your people can run the system themselves.
Is a bespoke AI solution what you actually need?
Not every organisation needs bespoke AI development. Custom AI systems are usually the right move if:
- You have unique processes that generic tools cannot handle well.
- You need AI that works with your data, systems, and governance requirements.
- You want long term advantage, not just parity with everyone else using the same tools.
- You already understand AI basics and want to move beyond experimentation.
If you are still at the stage of getting teams comfortable with AI, it might be better to start with training or consultancy and then move into bespoke builds later.

Bespoke AI Solutions
What is a bespoke AI solution?
A bespoke AI solution is a custom-designed system that uses AI to support or automate part of your business in a way generic tools cannot. Custom AI development in the UK means building around your data, your workflows and your regulatory obligations. Hartz AI is led by Craig Hartzel, who brings psychology-informed change management to the human side of every build.
A bespoke AI solution is worth building only when an off-the-shelf tool cannot reach the data, systems or rules the work depends on.
On what adopters spend, the executive summary of the Department for Digital, Culture, Media & Sport report AI activity in UK businesses states: “In 2020, the 432,000 companies in the UK who have already adopted AI, spent a total of £16.7 billion on AI technologies.”
Spending on AI is not the same as getting value from it, so Hartz AI checks whether an existing tool would do the job before proposing a custom build.
Security and governance are designed in from the start. Our builds follow the secure-by-design principles set out in the NCSC Guidelines for secure AI system development, so access, data handling and monitoring are agreed before any model touches your information.
At Hartz AI, bespoke solutions can include:
- Private GPT style assistants that live inside your organisation and know your context.
- Custom workflows that connect AI models to your internal tools and processes.
- Internal tools that help teams search, summarise, or act on your data more intelligently.
- Automation systems that remove manual steps and reduce repetitive work.
The goal is not to build something flashy. The goal is to build something that meaningfully improves how you operate and gives you an edge that is hard to copy.
Discuss a bespoke AI ideaWho bespoke AI solutions are for
Bespoke AI work is best suited to organisations that:
- Already see clear, repeatable processes that are good candidates for automation or augmentation.
- Have teams who are comfortable with AI concepts and want to move beyond basic prompts.
- Need AI systems that respect specific compliance, security, or governance rules.
- Care about building capability, not just buying another tool.
If you are not sure whether you need something bespoke, consultancy is often the best first step. We can help you work out whether a custom build is justified.
Start with AI consultancyWhat types of custom AI tools can you build for a UK business?
Every build is unique, but most bespoke AI projects for SMEs fall into a few practical patterns. Here are the most common types of custom AI tools we create to help you build AI for your company.
Private GPT style assistants
AI assistants that understand your policies, language, and processes, available only to your teams.
- Internal knowledge assistants for staff.
- Support assistants that help answer complex, context heavy questions.
- Guided tools that help team members follow best practice processes.
AI powered workflow automation
Systems that use AI to route, summarise, transform, or act on information so your team can focus on higher value work.
- Automated document processing and summarisation.
- Lead triage or case routing based on natural language inputs.
- Internal workflows that reduce manual copy paste or repetitive checks.
AI driven data and insight tools
Tools that help you query, explore, and understand your data in natural language so you can make better decisions faster.
- Internal search across documents, notes, or knowledge bases.
- Dashboards that combine AI summaries with key metrics.
- Decision support tools that surface the information leaders need most.

How does Hartz AI build a bespoke AI solution?
Every bespoke build follows the same four steps. A custom system is the result of understanding and planning, not the first thing we reach for.
The AI Playbook for the UK Government tells teams to understand the problem, the data and the limitations of AI before committing to a build. We apply the same order of operations to SME projects.
- ASSESS
Understand where you are with AI today
We look at your processes, data, systems and team skills to find where a custom build would genuinely help, and where an existing tool would do the job.
AI consultancy - PLAN
Create a practical AI roadmap
We agree scope, costs, success measures and governance in writing before any build work begins.
AI governance - BUILD
Implement AI solutions with your team
We build alongside your people, so the team that will run the system understands how it works from the first day.
AI implementation - SUSTAIN
Embed AI capability for the long term
We hand over documentation, training and internal champions, so your organisation can run and improve the system on its own.

What results do organisations see from bespoke AI?
Tailored AI for business is not about doing something flashy with new technology. It is about building strong, durable advantages into how your organisation works. AI solutions for your business should deliver measurable value, not just novelty.
The UK regulates AI through existing sector regulators rather than one central AI law, an approach set out in the government's pro-innovation approach to AI regulation white paper. That is why governance has to be shaped around your sector, your data and your obligations rather than copied from a template.
Capability matters as much as the code. 85% of clients are self-sufficient in AI within 12 months (Hartz AI client outcomes), because we build alongside your team and hand over documentation and training rather than creating dependence on us.
Hartz AI builds bespoke AI solutions alongside the client’s own team, so the organisation can run the system without relying on Hartz AI.
- Better fit between your tools and your reality, because the system is designed around you.
- Higher efficiency as manual, repetitive work is reduced or removed.
- More reliable decisions when AI helps surface and structure information in context.
- Competitive differentiation that does not disappear the moment a new public tool is released.
How we work
- Capability over dependency: build your team's skills, not reliance on us
- Plain English always: no jargon, no buzzwords
- Evidence before action: data-driven decisions, stats must have sources
- Responsible by default: governance and ethics built into every engagement
Is a bespoke build the right next step?
A bespoke AI solution is usually the right move if:
- You can clearly describe the process or problem you want to improve.
- You have tried off the shelf tools and hit their limits.
- You are ready to invest in something that needs careful design and change management.
- You want your internal capability to grow alongside the system, not be dependent on it.
Bespoke AI builds at Hartz AI are from £10,000 + VAT. A smaller AI Automation Sprint is from £3,000 + VAT and a pilot or proof of concept from £7,500 + VAT. Scope, timescales and cost are agreed in writing after discovery, before any build work begins.
If you are not sure whether you are at that stage yet, a short consultancy engagement can help you decide.
