Cosium develops cloud-based software solutions and devices for the healthcare industry. In the few years since its inception in 2003, Cosium has acquired a dominant position as an influencer in software and hardware for customer-facing applications, e.a. optical stores and audition centers, as well as helping to manage from behind the scenes with our Business Intelligence tools and innovative use of leading-edge technologies. Cosium is more than software: we offer a complete ICT outsourcing service, able to support customers from large to small, even distributed in different countries; we offer services to the industry, from 3D representation and applications to custom-designed electronics for optical retail and domiciliary care. Our international team based in Versailles is rapidly expanding to be able to offer our powerful and innovative solutions to more locales, for the benefit of healthcare professionals. Cosium is also an important Open-Source software contributor. The company authored code for many projects including Chromium, Hibernate, Apache Maven, Jenkins, Keycloak and Spring.
