About Thomas

I am an Interim Manager for Product Management, Portfolio Management, Project Management, and Business Development with over 18 years of international experience.
I am the bridge builder between technology and management in intercultural environments, especially in the German-Japanese context.

Companies bring me in during critical phases when leadership gaps arise, strategies are unclear, or complex projects stall. I ensure clarity, speed, and long-term stability in critical areas.

Your benefit: I resolve what is blocked in critical phases: product chaos, intercultural friction, strategy gaps.
- Immediate effectiveness – no long onboarding
- Clarity in product and portfolio strategies
- Accelerated decision-making processes and market launches
- Bridging leadership gaps and stabilizing during change phases
- Intercultural bridge function in global teams

My motto: Resolving Complexity, Delivering Clarity. Getting Things Done.
