mementor develops and markets digital medical products in sleep medicine and related fields. Founded originally in 2014 in Switzerland by Dr. Noah Lorenz, Alexander Rötger, Jan Kühni, and Daniel Rotzetter, mementor has had its headquarters in Leipzig since January 2020. The company focuses on "Apps on prescription," addressing where conventional patient care reaches its limits, aiming to remove barriers to treatment and provide affected individuals access to evidence-based therapy methods.

mementor's team aims to equip affected individuals with effective digital health tools for the treatment of physical or psychological illnesses. The goal is also to close existing gaps in healthcare provision and actively shape the future of digital medicine. Emphasis is placed on high scientific standards, an evidence-based approach, strict data protection requirements, and patient safety.

Both information security and patient safety are priorities. mementor is certified according to the DIN EN ISO/IEC 27001 standard, fulfilling all associated information security requirements. Their quality management system is certified under DIN EN ISO 13485, demonstrating that all necessary measures are taken to produce high-quality medical products. Compliance with these standards is annually confirmed through internal and external audits to ensure the highest quality and safety.

Since August 2, 2022, mementor DE GmbH is part of ResMed in Germany. This integration benefits both companies by combining expertise to provide more effective and accessible alternative therapies for sleep disorders and to close gaps in care. mementor operates as a distinct business unit within ResMed and serves as a foundation for future digital health developments. The management team includes Dr. Noah Lorenz and Katherina Jekerle (CEO), a senior director and member of ResMed Germany's executive management.

mementor developed the first permanently approved digital health application (DiGA) on prescription for treating sleep onset and maintenance disorders (insomnia) called somnio. It is based on cognitive behavioral therapy for insomnia, personalized to individual needs, and has demonstrated efficacy in randomized scientific studies.
