Thoughts.
Essays on product, AI and automation — and what changes when a Product Owner can build, not just manage.
How AI changes Product Ownership
AIFrom writing tickets to designing the systems that write them. What stays, what goes.
Stakeholders don’t want tickets, they want outcomes
ProductWhy the best product conversations start with the problem to solve, not the ticket to write.
Data beats opinions — most of the time
DataWhere analytics should make the call, and where product judgment has to take over.
Why product people should build more
SaaSShipping small tools yourself changes how you write requirements, estimate and decide.
When product people open their own PRs
DevHow AI could help product people turn ideas into working pull requests — and what that changes between product and engineering.
Where I think I’m wrong
MetaThe honest counter-arguments to everything else here. The objections to my own positions I don’t have clean answers to.
about
About me.
I’m a Product Owner from Hamburg with a strong interest in AI, automation and SaaS. I enjoy building systems that reduce repetitive work, make teams faster and turn messy processes into clear digital products and internal tools.
My path into product ran through online marketing, corporate communications and e-commerce, followed by an MBA in Data & Business Analytics at Hamburg Media School and a stint as a tech project manager in London. I entered product management by co-developing an eHealth app, and today I work across editorial and transactional products at Axel Springer Tech.
Outside of my day-to-day product work, I experiment with personal SaaS ideas, AI-assisted workflows and tools that help me think, plan and build better.
