Stephan Schenk is the designer-turned-entrepreneur behind Stapelstein, the German startup that is redefining children’s play through vibrant, ultra-light “stacking stones” made from 100 % recyclable EPP. Inspired by a childhood spent in a family of educators, Stephan set out to get kids moving in the classroom; what began as a dynamic chair concept in 2016 quickly evolved into an open-ended play system that lets children (and adults) build, balance, sort, and imagine without limits.
