Since 2016 exists the partnership between Dirk RossmannGmbH and the Bütema AG. With over 4,300 branches throughout Europe, ROSSMANN is one of the largest European drugstore chains. The collaboration began with a jointly developed app for online inventory management (OBF), which is still in continuous development and is used in all ROSSMANN branches. As of 2021, the cooperation expanded to include digital signage installations. After a successful PoC, the big rollout is currently on the way.
