What Rosenxt does

Rosenxt is a privately held Swiss technology group founded in 2023 by Hermann Rosen as a spin-off from the ROSEN Group, bundling former new-ventures activity around sensor, robotics, AI, and advanced-materials technologies for harsh-environment infrastructure. The company develops and operates solutions across four business fields: critical infrastructure integrity (subsea structures, offshore engineering structures, water-line integrity), performance optimization (AI-driven upstream reservoir optimization, EMAT clamp-on multiphase flowmeters, smart-manufacturing MES software, certification and auditing), systems and components (autonomous underwater vehicles, advanced offshore wind components including the patented Xelcor polyurethane slip joint, RoCoat wear-resistant coatings, and industrial diagnostic systems for rail, metal, and oil and gas), and a consumer watersports line through the Aerofoils partnership. It employs approximately 500 people across 16+ locations in Switzerland, Germany, the Netherlands, the UK, the USA, Canada, and Vietnam, anchored by a 110,000-square-meter flagship manufacturing site in Wietmarschen-Lohne. Revenue is generated through a mix of professional services (asset integrity management, structural health monitoring), hardware and components sales (AUVs, NDT systems, coatings, flow sensors), outcome-based managed services (Optimization as a Service tied to production uplift), and recurring software subscriptions (InQu MES), sold via direct enterprise field-sales engagement with operators of subsea, offshore, water, energy, mining, and industrial-manufacturing assets.
