A university spin off, Custom8, participated in a large open innovation project with some 10 partners (research institutes and companies). The project was partly subsidized by a governmental organization and named NXT_SLEEP. The aim of the project was to investigate an innovative way to monitor sleep disorders that can be done remotely (not necessarily in a hospital setting). A working prototype was realized as a result. Custom8 gained essential expertise that was relevant for further product development and management purposes. However, no joint commercialization took place with the other partners at the end of the project.
