AI-Native Product & Design Leader
The design leader moving closer to the model
I'm Tobias Treppmann, an AI-native product and design leader in Berlin. Fifteen years across complex B2B SaaS, and now Head of Product Design at Bibel TV, a broadcaster mid linear-to-streaming transformation — redesigning the app, shifting the team toward user-centric thinking, and doing it hands-on with AI in the loop.
