ABOUT ME

Hi, I'm Hermann.

I've spent over two decades merging product design, usability testing, and experience creation for some of the world's most forward-thinking organizations.

At LEGO, I led award-winning projects like the LEGO House—tested and refined with over 3,000 children and their families—to create unforgettable experiences. I saw kids' eyes light up when a concept truly hit the mark, and learned that no detail is too small when it comes to delighting your audience.

Today, I'm passionate about helping companies create innovative, meaningful products that blend human-centric design with cutting-edge AI. Whether you're refining an existing product or launching something entirely new, I'm here to guide you every step of the way.
