Bespoke AI Solutions For UK SMEs

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.

UK businesses invested £16.7 billion in AI in 2023 (DSIT), yet most off-the-shelf tools fail to address the specific processes that differentiate your business. Hartz AI builds tailored AI for business teams that need more than generic solutions.

Private and secure by designBuilt around your workflows and tools

In the UK, Hartz AI provides genuinely customised enterprise AI transformation consultancy, building bespoke solutions around your existing workflows, systems and team capability rather than applying generic templates. Led by Craig Hartzel, Hartz AI combines psychology-informed change management with hands-on implementation, tailoring training, tooling and governance frameworks to each SME's specific processes, data and goals. Bespoke AI solutions from Hartz AI are custom-built AI implementations, designed around a specific UK SME's workflows, data and objectives rather than off-the-shelf tools, delivered alongside training and governance support.

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.

What Do We Mean By Bespoke AI Solutions?

Bespoke AI solutions are custom-designed systems that use AI to support or automate parts of your business in a way generic tools cannot achieve. Custom AI development in the UK means building around your data, your workflows, and your regulatory constraints.

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.

Who 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.

How Do Bespoke AI Solutions Fit Into Your AI Journey?

Bespoke builds should not be the first thing you do with AI. They work best when they are the result of learning, strategy, and early implementation work. Here is how bespoke AI development connects with the rest of your Hartz AI journey.

The sequencing is not just our opinion. 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.

Step 1

Understand And Explore

Build shared understanding and confidence across teams with AI training and workshops.

AI Training
Step 2

Diagnose And Plan

Use AI consultancy to understand your readiness, risk, and where custom solutions make sense.

AI Consultancy
Step 3

Implement And Optimise

Start with practical implementation projects and small automations to prove value and refine ideas.

Step 4

Build Bespoke And Embed

When the need is clear, move into bespoke AI systems supported by internal champions and leadership.

What Results Do Organisations See from Bespoke AI Investment?

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.

  • 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.

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 start from £10,000 excluding 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.

FAQs About Bespoke AI Solutions

What Do People Ask About Bespoke AI Solutions?

These questions cover how we think about custom AI systems, how they are scoped, and how they connect with training and consultancy.

No. Part of scoping a bespoke AI solution involves understanding what is realistic with the data and systems you have now. We assess data readiness during discovery and advise on what preparation is needed. Many successful projects start with imperfect data and improve over time.
Standard implementation focuses on configuring and connecting existing tools. Bespoke AI development involves designing and building systems unique to your organisation. They may use standard components, but the architecture, integration, and governance are specific to your requirements and workflows.Learn about AI implementation →
Our goal is to build systems your teams can understand and operate over time. We provide documentation, training, and can establish AI champion programmes internally. For complex builds, we can agree an ongoing support arrangement, but we do not aim to create dependence.Explore AI champion programmes →
The best starting point is usually a short consultancy engagement where we explore potential use cases, assess readiness, and agree what success looks like. From there, we decide together whether a bespoke solution is the right move and how to scope it practically.Start with consultancy →
Costs depend on the complexity and scope of the build. Bespoke AI builds at Hartz AI start from £10,000 excluding VAT, with the final figure set by the number of integrations, the state of your data and the governance work required. Discovery always comes first, so you understand costs before committing.Book a discovery call →
Yes. Bespoke does not always mean expensive. Many UK SMEs start with a single custom AI tool that solves a specific problem, then expand as they see results. The key is scoping the build to match your budget and priorities rather than trying to automate everything at once.Book a discovery call →
A bespoke software solution is a system designed and built for one organisation rather than sold as a standard product. Bespoke AI applies the same idea: the underlying models may be off the shelf, but the workflows, data connections, interface and governance are built around how your business actually operates.
The 30% rule is a rule of thumb that roughly 30% of an AI project is the technology and the remaining 70% is data, process and people. It is not a formal standard, but it matches what we see in practice: bespoke AI succeeds or fails on change management, not on model choice.See how AI training builds the other 70% →
Follow four steps: assess where you are with AI today, plan a practical roadmap, build with your team, then sustain the capability internally. Many teams create their own simple tools with custom GPTs or no-code platforms. Bespoke development earns its place when the tool must connect securely to your systems and data.Start with an AI readiness assessment →
Yes, and for simple jobs you should. Custom GPTs, no-code automation platforms and spreadsheet add-ins let a trained team build useful tools in an afternoon. Bespoke development earns its place when a tool needs secure access to internal data, an audit trail, or integration with systems no-code platforms cannot reach.Learn to build your own tools with AI training →
Yes, plenty. Hartz AI is one of them: a London-based AI consultancy operating UK-wide, registered at Companies House as The Hartz Company Limited (03848015), specialising in training, consultancy and bespoke AI builds for SMEs with 10 to 250 employees. Founder Craig Hartzel brings psychology expertise to the human side of adoption.
