A messaging app is primarily used for exchanging messages and files. A collaboration platform such as mantau goes a step further: it combines communication with shared appointments, documents, forms and organisational workflows. This enables groups not only to communicate with one another, but also to organise their collaboration directly within a single application.

One of mantau’s key features is its decentralised group management. Groups and sub-groups can be organised and managed independently, without every change having to be made by a central IT administration team. The group structure can be adapted at any time. In addition, the platform offers integrated tools for communication and organisation, as well as data protection-compliant operation in German data centres.

mantau is suitable for small groups as well as for larger companies and organisations with numerous departments, teams or sites. Typical areas of application include companies, clubs, associations, church parishes, schools, nurseries, social organisations and local authorities. Thanks to flexible group structures and a range of usage models, mantau can be adapted to meet a variety of organisational requirements.
