Niclas Braun.
Building companies.
Questioning what comes next.
I build at the intersection of AI, autonomy and the physical world. Today, that work is 4SI.
What I’m working onWhen software can act in the world, how do we know it should?
At 4SI, I work on physical trust infrastructure: connecting digital decisions to verifiable people, objects and events.
The questions are practical. Is this identity genuine? Is this object authentic? Is this action authorized? My focus is how those answers can remain dependable as AI and quantum computing change the assumptions behind digital security.
