About APPARENS

Jeroen Janssen — Founder Apparens exists because I kept seeing the same pattern — in government, in media, in consulting, in enterprise IT.

Every dependency is tested. Every claim is held to evidence. Apparens is not a traditional consultancy. It is an applied research practice — an ongoing experiment at the frontier of what AI can do for strategic decision-making. What I learn here, I bring back to my work at the Belastingdienst. And once a year, I bring it to the classroom as a guest lecturer in AI strategy and g
