AI that performs in production
I help companies build, advise on and lead AI that performs in production, not just in the demo. Twelve years building it, six of them inside regulated finance, where the bar is highest.
Built and shipped inside
MIT put a number on it: 95% of enterprise GenAI pilots show no measurable P&L impact. The demo is the easy 10%; integration, model risk and audit are the invisible 90%, and clearing it is what I have done for twelve years.

AML/KYC & credit decisioning automated
Manual onboarding replaced end to end across Finland, Sweden and Denmark, through a bank's second line of defence.
Defined and delivered AML/KYC and credit-decision automation across retail and SME segments in Finland, Sweden and Denmark, replacing manual onboarding end to end. Pioneered the compliance-first delivery model the bank adopted organisation-wide. An earlier credit-automation design took SME automation from 5% to 50% and added ~€1M in annual profit.

Annual value from enterprise AI
20,000+ editorial hours a year given back, and a RAG assistant serving 2M+ monthly users.
Led enterprise AI transformation recovering 20,000+ editorial hours a year, including the team working on AI Forge, the group's AI toolbox. Shipped a RAG assistant that lifted session duration 39% for 2M+ monthly users, across 380K+ AI-assisted content events a year.
Acquired
Drove product-market fit to a successful exit
Explainable AI for fixed income, taken from inherited MVP to product-market fit and acquisition by BondIT.
Took an inherited MVP for explainable AI in fixed-income asset management to product-market fit, directly enabling acquisition by BondIT. Explainability treated as a first-class, regulator-ready feature, not an afterthought.

ARR as Head of Product
Built the GPU-compute offering and the partnerships that scaled Germany's first AI cloud 45x.
Owned the product vision and roadmap that scaled ARR 45x. Built the GPU-compute and MLOps offering, forged partnerships with Intel Habana and NVIDIA, and landed the largest enterprise contract at the time (€300K+).
“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.”

03 EU AI Act & ISO 42001
High-risk obligations moved to December 2027. The Article 50 transparency duties went live in August 2026 regardless, and the firms that wait will retrofit a portfolio instead of building to the standard. I get you certification-ready.
