About David

Location: Düsseldorf | Area of Operation: Germany, Netherlands & Belgium
I take on projects in mechanical engineering, technology, and electronics remotely as well as on-site. On-site appointments by arrangement, nationwide and in the Benelux region.

I support technology, industrial, and medium-sized companies in measurably increasing growth, profitability, and operational excellence – as an interim manager, management consultant, or project leader.

With over 14 years of experience in management, consulting, and technical leadership, I take responsibility where companies are facing transformation, scaling, turnaround, or internationalization. My focus is not on concepts, but on implementation, results, and sustainable impact.

What makes me special:

- Ex-Managing Director with full P&L responsibility (up to €70 million in revenue, up to 200 employees)
- Deep technical background combined with entrepreneurial management
- Proven revenue increases up to +35%, turnaround and profitability programs
- International experience (Europe, USA, global sales organizations)

Typical fields of application & added value:

- Interim Management (Managing Director, Operations, Segment or Department Head)
- Growth and Profitability Programs
- Operational Excellence & Restructuring (Processes, Organization, Costs)
- Sales and Marketing Transformation (Lead-oriented systems, global activation)
- Technology & Innovation Strategies (Roadmaps, new markets, digitalization, AI)
- M&A-related projects (Integration, preparation, carve-outs)

Project types & results:

- Development and implementation of growth strategies including market and product diversification
- Turnaround projects with sustainable performance improvement
- Introduction of structured strategy and management systems (e.g., Hoshin Kanri)
- Acceleration of development and decision-making processes
- Professionalization of international sales and organizational structures
