Sven grew up in Cologne, Germany, where he lit small-scale theatre shows after high school, complemented with lighting for movies, advertisements, and music videos.  His subsequent studies of theatrical lighting design in London led him to develop a keen interest in digital technologies and their potential for the live arts

In 2001 he joined up with Dick Straker and his company mesmer to explore and further the use of imagery and projection in the live arts. For the National Theatre, London mesmer provided realization and design services for over 20 productions and established a video department which introduced technologies and techniques that have become de-facto standard today. Together with Straker he also conceived the video system and process that realized the technologically groundbreaking musical The Woman in White in the west end and Broadway in 2004.
