H&Z Rises to #8 in Lünendonk 2025

Clients trust H&Z for pragmatic transformation, resilient procurement, AI-driven innovation, and ESG with substance, delivering 15% growth in a volatile market.

Why clients choose H&Z

Our growth is not fuelled by market momentum, but by consistently delivering value where it matters. Clients across industrial and mid-sized sectors rely on H&Z to support:

  1. Performance improvement and operational excellence

  2. Resilient supply chains and procurement transformation

  3. Digital innovation through pragmatic use of AI

  4. ESG integration with real substance instead of greenwashing

We see AI as a tool, not a miracle. 

It enhances both internal processes and client projects, creating measurable value. 

However, as Stefan Aichbauer, Managing Partner at H&Z, emphasised in a recent Börsen-Zeitung interview: “The question remains: how long will clients continue to pay for certain deliverables?”
Stefan was referring in particular to research tasks, where AI can significantly accelerate routine work. Yet, this also raises the bar:
Interpersonal skills, contextual judgement and critical thinking will become even more essential especially in areas where trust, nuance and relevance are key to value creation.

Strategic momentum through capability expansion

This rise in the ranking also reflects our expanded capabilities. The integration of Haselhorst Associates has strengthened our restructuring expertise, while H&Z Digital continues to grow rapidly, helping clients transform with scalable technologies.

Thank you to our clients and our team!

Our success is rooted in collaboration. We are grateful to our clients for their trust and to our exceptional team for delivering measurable results with head, heart and hand.
