It's all about the group
Group administrators are the designers of the group. As an administrator, you create your group(s) and add the features "Messages", "Events", "Files", "Requests" etc. as required.
This is very simple - and can also be adapted later.

Subgroups - structure, overview and order
Within groups, any number of further groups can be created. Regardless if you need the same or different members and depending on the purpose: person or topic related.
Group administrators create these subgroups (groups-in-groups), choose appropriate group names and assign members. Subgroups can be rearranged at any time. mantau supports constantly changing organisations with many projects.
This way you can chat topic related and clearly assigned. You can store files similar to the way you are used to from the conventional file manager.

The implementation of mantau at DRK-Sozialwerk Bernkastel-Wittlich marks significant progress in our internal and external communication, but also in the digitalisation of the company. Thanks to the software solution, we can optimally network our 560 employees, digitalise important workflows and processes and efficiently fulfil our documentation obligations. The collaboration between us and EXEC during the implementation is great and a lot of fun for everyone. We are very satisfied.
Mr. Matthias C. Hommerding
DRK-Sozialwerk Bernkastel-Wittlich gGmbH, Authorised signatory and deputy managing director, commercial management
The mantau app serves as an effective communication medium for the Goethe-Schule Höhr-Grenzhausen. It enables a quick and uncomplicated exchange between teachers, parents and extracurricular cooperation partners. Functions such as message transmission, form creation and feedback optimize the flow of information.
The user-friendly interface ensures that everyone involved can easily access important information, making communication transparent and efficient. mantau thus supports educational work and promotes active cooperation within the school.
We started with the organisation of the First Communion in Wachtberg, which was a complete success! Since December, we have therefore extended the use of mantau to all interested parishioners and provide information about current events or the progress of our merger into the Meckenheim-Wachtberg pastoral unit, for example. With mantau, we are close to the parishioners and their desire to strengthen the community.
As a daycare centre, we were looking for a suitable communication platform for parents, educators, the team and the provider for a long time. We found all this in mantau! The APP is ‘child's play’.
Thanks to the quick help and good co-operation with EXEC, problems and stumbling blocks are solved in a solution-oriented manner. Now we have more time for the important things again:
PLAYING, LAUGHING, SINGING + EXPLORING WITH OUR KITA KIDS!
We have been using mantau since the founding phase of our cooperative to communicate with all stakeholders, exchange documents and hold video conferences. Since inframeta eG began its operational work and formed teams for product development, marketing, sales and support, mantau has helped us to organise structured, seamless and audit-proof project communication. In addition, mantau saves us from having to store redundant documents. Communication within the Executive Board and the Supervisory Board is also easily handled via mantau. In a next step, we will recommend mantau to our cooperative members as a communication tool for infrastructure construction projects.
With mantau, the municipality of Wirscheid has created a modern communication channel for its citizens. It allows us to reach many households reliably and quickly, particularly in a timely manner. We also use the app for our collaboration within the local council. For example, we used it to organise the elections and coordinate tasks relating to photo shoots, flyer creation and distribution in the town. Everyone got involved - and it was a great way to make work easier for us organisers. We are delighted - and the response from the residents has been consistently positive.
It was important for us to find a communication platform for our association work that was easy to use and at the same time compliant with data protection laws. We were able to create association groups and sub-groups very well. The organised file storage within the groups is very practical and enables us to easily organise recurring events. In addition, we particularly like to use the appointment function with the option to cancel or add events. It's great that the support is always easy to reach and reacts immediately when we have questions.
After receiving the green light from the local council, the extraordinarily extensive and rapid help from EXEC employees enabled me to promote the platform to our residents through publications and flyers, and the number of users has been growing steadily ever since. In addition to groups for citizen information, the local council, committees and working groups, we also offer our booking plan in mantau along with a form for renting our barbecue hut. This makes my voluntary work easier, as I can respond to enquiries from anywhere via my smartphone. I can only recommend mantau. We will continue to expand it in our community and I'm sure it will inspire many new users, young and old alike.
inframeta eG helps to further digitize municipal civil engineering projects. And for us, infraMessage is the key tool for proactively informing residents about construction sites. Tailored to specific target groups and delivered at the right time, infraMessage sends push notifications—for example, about when a house connection will be installed or when the water supply will be shut off. Very specific, important information. Since we had already been using mantau for our cooperative, it quickly became clear that we could also offer an infraMessage solution using mantau’s features. The cost of a white-label solution is much, much lower for us than developing our own. That’s why we’re very happy to have found a cost-effective white-label solution.
We are active with different groups in the association and with mantau we are able to get the different communication streams under control. We use the app for our daily board work and for planning the carnival season with a total of 5 major events. It is very helpful for everyone to be able to network with just one app in such a large association with almost 500 members.
A great example that saved us a lot of work was the order form for our parade costumes: everyone could use it to select their costume in their size and order it internally, and the app then gave us the finished shopping list. mantau also works very well for our dance groups. The currently more than 150 dancers in 8 groups have replaced their WhatsApp groups, now plan their training sessions in mantau and use it to organize their annual show dance tournament together.
Mr. Christoph Fohr
Karnevalsfreunde Blau-Gold Ransbach-Baumbach e.V., President
We are pleased that we have found a suitable solution with mantau, which helps all our groups including helpers, parents, coaches and trainers with coordination, appointments and communication about our work, so that we can concentrate on the essentials.
In addition to our website and social media presence, we use mantau to organise our diverse collaboration in groups.
We use a news channel to inform our parishioners about the many events, programmes, activities and gatherings at our church locations.
As a pastoral team, we use the various opportunities to communicate with people and involve them.
Mr Pastor Xavier Manickathan
Katholische Kirchengemeinde St. Peter und Paul im Kannenbäckerland, Head pastor
We use the app to organise a large part of our pastoral work. It is also a modern working platform for our confirmands and the parents of the communion children.
Everything is possible, from registration forms to group chats. This noticeably reduces the workload in the parish office.
Mrs Manuela Dickob
Katholische Kirchengemeinde St. Peter und Paul im Kannenbäckerland, Parish secretary, central parish office
We use mantau in the parish council for our committee work, e.g. for inviting participants with feedback options, providing minutes and collecting topics.
mantau is a very good project app for organising our numerous events.
Mr Dr. Florian Dittrich
Katholische Kirchengemeinde St. Peter und Paul im Kannenbäckerland, Chairman of the parish council
We now have tablets and smartphones in every children's group.
mantau ensures that information is passed on reliably and at short notice. Because things usually have to happen quickly, e.g. when a message arrives in the morning before the start and we have to reorganise quickly.
It was very important to me that it could be customised to our daycare centre. And that I was able to set it up myself - without IT specialists - in a short space of time.
The group diary is particularly important for swimming training. Parents can see all the dates at a glance. The coaches always know how many children will be attending the training session thanks to the acceptances and cancellations. Short-term changes and notifications of all kinds can be distributed to everyone at the click of a button via the messages.
Mr. Frank Friedrich
DLRG - Deutsche Lebens-Rettungs-Gesellschaft Ortsgruppe Ransbach-Baumbach e.V., Press and Public Relations Manager
The use of mantau works great. For example, it has simplified the organisation of the team meeting enormously (with one click you could see how many people had agreed to attend and plan the meal accordingly), the schedule is in one central place for everyone to read and the possibility to synchronise the appointments with the calendar from the mobile phone inspires many.

FAQ: mantau features
mantau combines several key collaboration features: a messaging service for communication, cloud storage for files, a team calendar for events, video conferencing for meetings, as well as forms, tasks and role and permissions management for structured organisation.
The messenger enables one-to-one and group chats within teams, projects or organisations. Messages are organised by group and can also be used for structured communication, sharing information or as a newsletter service.
Cloud storage is used for the centralised storage and organisation of files within groups. Documents, images and files can be shared, stored in a structured manner and managed using defined access rights. This creates a shared, version-controlled database.
The team calendar enables the joint planning and management of events within groups. Users can create events send invitations, manage acceptances and cancellations, and synchronise appointments with other calendars.
Yes. In many organisations, mantau replaces a number of standalone solutions such as messaging apps, cloud storage services, calendar tools and video conferencing systems. All these functions are integrated into a single platform and interconnected, enabling work processes to be managed centrally.
The collaboration features are suitable for businesses, clubs, associations, social organisations, schools, local authorities and project groups. They are designed to support structured communication and collaboration in a variety of organisational contexts.
Yes. mantau is developed in Germany and operated in certified German data centres. The platform relies on encrypted data transmission, controlled access rights and data protection-friendly processes. This makes mantau particularly suitable for organisations that have high standards regarding data protection and digital sovereignty.
