Marvin Messenzehl

I'm an AI architect at MVV Energie, the energy company based in Mannheim. I help people make sense of AI: I build prototypes and tooling, enable teams to put it to work, and help the company through its transition to becoming AI-driven.

Before MVV, I was a design engineer at DAYY®, Germany's best design agency, working with brands like Red Bull, Allianz, Volvo, and Isar Aerospace. I cared about the full picture: from the first sketch to the shipped thing.

Before DAYY®, I led design on the RTL+ iOS and tvOS apps. I started with podcast and music features, but over time took on the full scope of their mobile and TV platforms, shaping the experience for millions of users.

I started out on the engineering side. My master's in business informatics at the University of Mannheim led me to building and running the Innovation Lab at SV Informatik. It was a small team exploring new technology trends in insurtech. That's where I fell in love with building digital products.

After that I went freelance, working with companies ranging from early-stage startups to large corporates: LBS Group, Notch.so, enduco, ONVY, Hello Design, SAS, and Instaffo. Alongside that, I teach UX/UI design with Memorisely, helping the next generation of designers find their footing.

Outside of work I'm obsessed with endurance sports, reading, and spending time with my family and friends. I live in the German countryside.
