About
Learned in goal. Proven in business.
I played goalkeeper at professional level in Austria, second division. The position teaches you things no MBA does. You stand alone. Every mistake is visible. You decide in milliseconds, with incomplete information, under pressure. And then you get up and do it again.
That mindset is what I brought into entrepreneurship in 2000. And never left.
26 years of building KEEPERsport: e-commerce, product development, brand building, retail, marketing, European expansion. I have built webshops, developed products, entered new markets, built teams, and made the decisions that keep a company moving forward for over two decades. No single speciality. That is the point.
What moves me is not the title. It is the work. The 1% improvements that compound over years. The decisions that are uncomfortable but necessary. The conviction that niche markets can scale, if you are patient enough and sharp enough to outmanoeuvre the big players.
I think in scenarios, not in headlines. I am sceptical of simple answers to complex questions. And I have a strong bias for action over endless discussion.
Long-term investor in digital assets and capital markets. I believe in decentralisation as a structural shift, not a trend.
For the last two years AI has become my operational infrastructure. Not a trend to follow. A tool that compounds.
Family man. Father of two. Based in Austria.

Orchestrating, not operating.
The goalkeeper orchestrates the entire defence. He reads the game before it happens, sets the wall, decides under pressure with incomplete information in real time. That is exactly the shift happening in my work right now. I am no longer the operator. I am the Product Architect, orchestrating agents.
Something flipped in late 2025. The way we build software, run operations, communicate, research. It changed. Not gradually. A phase shift. And it is just the beginning.
What occupies me: Building AI-native operations at KEEPERsport. Code generation, operations, customer communication. AI writes. We review. We ship. Things that used to take weeks collapse into a day.
At home, I run my own AI assistant on my own hardware. It manages our family calendar, reminders, logistics, home systems. Persistent, autonomous, under my control. One goal: automate everything that does not require a human decision.
What I believe: A small, sharp, AI-native team can outperform a traditional department of fifty. That is not a prediction. For me, it is already reality.
My take.
I write about AI, business and KEEPERsport. Not from theory. From the middle of it.

Just listened to the new podcast with Andrej Karpathy. 66 minutes. Couldn't stop. One line hit me hardest: "I haven't typed a line of code since December." Not because he stopped building. Because the way we build changed. Permanently.
