About Sarah
As a Product Professional with many years of experience in Product Experimentation, Data, Product Operations, and Product Management, I help companies not only build digital products but drive them to lasting success. My approach is holistic: I connect technology, culture, and individual enablement.
My Focus:
- Strategy & Ecosystems: Building scalable product ecosystems and sustainable tech stacks.
- Transformation & Culture: Breaking down cultural barriers and establishing an outcome-driven mindset.
- Enablement: Targeted training to close knowledge and application gaps at the individual level.
- Insights: Validation through data (A/B testing, quantitative and qualitative user research) as the foundation for every product decision.
My Experience:
- From dynamic scale-ups to complex enterprises, from e-commerce to mobility — I know the specific challenges of different industries and organizational structures.
- I bring experience from multiple disciplines within product development: Product Management, Experimentation, User Research, Product Operations, Analytics.
- B2C, B2B
- Web, App
My Way of Working:
Data-driven, outcome- and solution-oriented, and sustainable.
My Guiding Principle:
I firmly believe that valid insights and reliable data make the decisive difference, and that the best products emerge in scalable ecosystems where solid knowledge, customer-centricity, and an outcome-driven mindset come together.
