02About
I was born in 1997 in Ostfildern near Stuttgart and registered my first business at 17 – I’ve been self-employed ever since. Today I run heyhey., a creator management agency that brings creators and brands together.
What drives me is less about titles than about how things work: how does a company actually run, where does it get stuck, and what happens when you make it better? I’ve built most of our processes myself – increasingly with AI as a tool, not a buzzword.
Right now I’m looking for a new challenge: insight into fields I don’t know yet, and companies I get to understand from the inside.
03What I do
01
Creator management
heyhey.: creators, brands, campaigns – and everything that needs organising in between.
02
Processes & AI
Understanding workflows, simplifying them and automating them with AI tools. From an internal operating system down to a small script.
03
New paths
Open to projects, mandates and conversations in fields I don't know yet – especially where companies are being made fit again.
