Meet the Team
Behind Your AI Success
We're a passionate team of AI experts, educators, and strategists united by one mission: making AI accessible, practical, and empowering for UK SMEs.
Why We Started Hartz AI
It all started with a simple observation: UK SMEs were being left behind in the AI revolution. Not because they lacked ambition, but because AI felt intimidating, complex, and out of reach.
We saw brilliant businesses struggling with jargon-filled consultants who created dependency, or being overwhelmed by online courses that offered no real support. We knew there had to be a better way.
So we created Hartz AI - a different kind of AI partner. One that speaks plain English, builds your capability, celebrates your independence, and measures success by your confidence, not our billable hours.
"We believe every UK SME deserves access to AI that empowers, not intimidates. That's why we do what we do."
