About Hartz AI: A UK AI Consultancy Built for SMEs
Not sure who to trust with AI? We understand. Most consultancies talk in jargon and build dependency. Hartz AI does the opposite: plain English, practical skills and a clear goal of making your team self-sufficient.
Hartz AI is a London-based AI consultancy that helps UK SMEs with 10 to 250 employees build real AI capability. Founded by Craig Hartzel, we deliver hands-on training, strategic consultancy, bespoke implementation and governance frameworks. Over 500 professionals trained, 85% of clients self-sufficient within 12 months.
Who we are
Who is Hartz AI and what do we do?
Hartz AI is a UK AI consultancy based in London that helps small and medium-sized businesses adopt artificial intelligence with confidence. Craig Hartzel founded Hartz AI because most SMEs were being left behind — not for lack of ambition, but because AI felt intimidating and advice was buried in jargon.
We work exclusively with UK businesses employing 10 to 250 people. Our clients include professional services firms, charities, sport governing bodies, education providers, real estate agencies and retailers. The common thread is a desire to use AI practically, not just talk about it.
The company is registered as The Hartz Company Limited (Companies House: 03848015) and is ICO registered (Z7605179). We operate from the Wohl Enterprise Hub in London N3 and deliver services on-site and remotely across the United Kingdom.
Why trust Hartz AI
Why should you trust Hartz AI with your AI journey?
Trust starts with transparency. We publish our pricing, share our methodology and measure success by how quickly your team becomes independent. Hartz AI builds capability, not dependency — 85% of our clients run their own AI initiatives within 12 months.
Craig Hartzel founded Hartz AI with a background in psychology and over two decades of business experience. That combination shapes everything we do: we listen before we advise, we teach before we build, and we check understanding before we move on.
We are a Companies House registered business, ICO registered for data protection, and winner of the Work Avenue Micro Business of the Year 2024. Our team includes Rivka Abecasis, who leads AI compliance, and Samuel Kelly, who leads technical development. Every engagement is backed by structured frameworks, not improvised guesswork.
What we offer
What services does Hartz AI provide?
AI Training
Hands-on workshops from half-day introductions to three-day intensive programmes. Your team leaves each session confident enough to use AI tools the same week. Over 500 professionals trained to date.
AI Consultancy
Strategic consultancy and fractional Chief AI Officer services for UK SMEs. From AI readiness audits to roadmapping, we help you move forward with a clear, time-bound plan.
AI Implementation
Bespoke AI solutions built into your existing tools and workflows. Every implementation includes team training and documentation so your people run it independently.
AI Governance
Compliance frameworks aligned with evolving UK AI regulation. Rivka Abecasis leads AI compliance at Hartz AI, helping you use AI responsibly and reduce risk.
Our approach
How does Hartz AI work with clients?
Every engagement starts with listening. We run a free 15-minute discovery call to understand where you are now and what matters to your business. There is no pitch, no pressure and no obligation to continue.
From there, we recommend a starting point that fits your budget and timeline. Most clients begin with a half-day training workshop or an AI readiness audit. Both produce immediate, practical value your team can act on the same week.
As your confidence grows, we scale with you: from workshops to consultancy, from consultancy to implementation, and from implementation to independent AI leadership. The goal is always the same — your team running AI initiatives without us.
