With over 15 years of experience in audio production, Flo has completed numerous creative projects — always with a keen sense of quality, emotion and impact. One focus of his work is on auditory marketing opportunities: “Audio is more than just a trend — it moves people and strengthens brands.”

As Product Owner, Flo is responsible for the HEAROOZ children's podcast portfolio. He manages strategic development and is the central point of contact for all content-related, technical and conceptual issues.

In doing so, he combines creative ideas with clear strategic thinking — with the aim of creating high-quality and entertaining audio formats for families.
