The Story Behind Thios

Peter Bartsch — Founder & Product Designer

From building skateboard ramps as a teenager to designing products for John Deere and scaling FourKites from $3M to $100M ARR — 15+ years of product design shaped a simple belief: everyone deserves well-designed spaces. Thios started with a question: what if building a backyard sauna or office was as straightforward as assembling furniture? Open-source plans, modular hex panels, and a 3D configurator later — here we are. No gatekeepers, no markups, just good design for everyone.
