Hartz AI

Company Description

Hartz AI is a UK AI consultancy and training provider that helps growing businesses turn AI from a board-level talking point into working systems.

We work with operations, technology and people leaders in organisations of typically 50–250 employees, the stage where AI ambition outpaces internal capacity, and where a stalled pilot costs more than the tools did. Three connected services, used together or on their own:

AI Consultancy. Readiness audits, workflow analysis and prioritised roadmaps with modelled ROI for every initiative, delivered in phases so you can stop, adjust or scale after each stage. Clients typically see 20-30% efficiency gains within 12 months and reach positive ROI in three to six. For leaders who need senior AI judgement without a full-time hire, we offer Fractional CAIO and ongoing advisory, alongside Governance and Responsible AI frameworks that stand up to board, client and regulator scrutiny.

Bespoke AI Solutions. Custom systems built around your workflows with your domain experts in the room, from document processing to multi-agent automation. Typical result: a 40-50% reduction in manual processing time. You own the IP and we transfer the knowledge to your team.

Hartz AI Academy. Role-based, hands-on training that moves teams from cautious to capable, with most people shipping their first working automation inside a week.

We work across professional services, charities, sport, education, real estate and retail.

Our approach is plain English, evidence over hype, and outcomes you can put a number against. We explain our reasoning, document what we build and hand it over. The measure of a good engagement is that you need us less over time, not more.

Founded by Craig Hartzel, Hartz AI is based in London and works with clients across the UK.
