Commercial & operational leadership · AI Manager (IHK)

Commercial substance. AI judgement.

Commercial and operational leadership in the industrial Mittelstand: structure for growth, controlling, ERP, proven cost reduction. As a certified AI Manager (IHK), I say where AI genuinely pays off in a business — and where it just burns money.

Profile

What drives me.

I take companies to the next level of commercial maturity: reliable numbers, clean processes and a team that comes along. Most recently I proved it as managing director: a third less fixed cost, four ERP rollouts, reporting and liquidity management built myself.

My foundation: more than 30 years in the industrial Mittelstand, strategic purchasing, operations, supply chain and commercial management, from the shop floor to the managing director's desk. Since 2020 I have deliberately taken on build-up and change mandates in mid-sized companies.

I lead with head and heart and negotiate hard but fair: a down-to-earth sparring partner for the management at eye level, close to the people all the way to the shop floor. As a certified AI Manager (IHK) I use new technology and AI with judgement, where it genuinely makes the business more efficient.
