AI product leader · Berlin
I have spent twelve years in AI and machine learning, taking AI products from concept to production at Danske Bank, Scorable, Genesis Cloud and Ringier. I also build in the open, run the Berlin chapter of the Agentic AI Foundation, and speak about what it takes to ship.

Speaking
My talks are about the other ninety: evaluation, governance, infrastructure and the people who have to sign AI off. For product, data and engineering audiences, at conferences, meetups and on podcasts.

Profile
In banking, asset management, AI infrastructure and media.


“Stefan is one of the brightest guys I've worked with. He went often beyond his role as product manager to also get his hands dirty in operations and architecture, and took on communicating complex and sometimes difficult messages to executives, and orchestrating complex operations, often dealing with compliance, with stakeholders across multiple organizations.”
“Stefan is an expert in Artificial Intelligence and High-Performance Computing, and a remarkable professional. His expertise spanned both software and hardware, going way beyond the level of depth I would typically expect from a Product Manager. He was always reliable, consistently meeting our milestones, and I genuinely enjoyed working with Stefan and his team.”
