Slow Business: How to? (deutsch)

Die letzten Wochen kam sehr viel Feedback auf meinen Artikel. Zum Teil kamen Gründer mit ihren eigenen Ideen bei denen sie technische Unterstützung oder Rat benötigen, zum Teil haben mir Gründer einfach nur erzählt, woran Sie gerade so arbeiten und wieder andere haben sie sich vor allem für meine eigene Idee interessiert, wie man den […]

Second-system effect

When building products and introducing new technology, I regularly see the second-system effect: A simple, well-functioning system reaches its limits and is then replaced by a much too big, bloated, overengineered system due to exaggerated expectations and exaggerated self-confidence – and everyone is unhappy. 🙂 You may have heard of it. In my practice, for […]

Slow Business & Climate (Tech)

Ich wende mich heute auf Deutsch an euch. Denn ich schreibe diesen Artikel nicht für die große Masse, die ihn über Google findet, sondern für den engsten Teil meines beruflichen Netzwerkes.

So this is a good lever for action biased people in the startup ecosystem. I write this, because I am involved in the launch of a nonprofit initiative (more […]


I did something called the PROTOTYPING.DIRECTORY. It offer tools, templates and inspiration for every situation during a startup / product lifecycle.

Zettel v1.0 – Shopping list prototyping – Google Spreadsheet

It’s Saturday. Saturday we do our weekly shopping. Every week one thing bothers me: The supermarket is sorted differently than the shopping list.
