mantau! The group manager.
Because the future of engagement is digital.
The app for organisations, associations and initiatives
Together. Easy. Organised. mantau!
Common interests, projects and goals is what brings people together. No matter if it is only a small group, an association with a voluntary or full time basis or a widely ramified decentralised organisation with thousands of members. Whenever groups come together to get things moving, they need well-functioning communication and smart organisation.
That's exactly why we developed the app mantau. A combination of messenger, secure cloud storage, shared calendar and more. Groups and roles provide an overview and as a multi-platform, mantau enables hybrid working. Simple, efficient from anywhere via phone, tablet or desktop PC. Ideal for heterogeneous groups, ideal for sharing, coordinating and storing data and knowledge.
By using mantau you create what gives your organisation a solid and secure future: team spirit and a healthy engagement.
Everything you need for your group(s). The group manager mantau!
Where several apps have been used for different purposes, mantau provides a single solution. For everyone.
Create groups, structure and tailor them to your needs.
mantau groups have members and features. Features like a calender or a data box can be added individually if needed. So every information is stored where it should be.
Within groups, subgroups can be created, depending on function and purpose. Whether for subsets of the people in the main group, (individual teams, departments, …. ). Or for topics or projects. You can even change the structure later or rearrange groups completely.
Messages: Chat, group chat, newsletter
Write in groups or just one-to-one, just as you are used to from other messenger-apps. In mantau these chats are structured and topic related. Use mantau messaging across any device or platform. mantau is also ideal for reaching out to large groups by sending newsletters.
All chats in mantau respect the members' privacy: personal data, such as phone number or e-mail address, are never revealed.
Security made in Germany.
Events - in the shared calendar
Coordinate events in the group, invite people, give responses to invitations - and all events are well-arranged in the shared - yet personal - calendar. You can automatically synchronise all calendar entries of your mantau groups with the local calendar on your mobile device.
Files - in the common data box
Store all documents, images, audios, and videos of your group in one place. Always available for all members. Simple as a file manager and always with sufficient storage volume. And of course securely stored in a German data center.
Create forms for the group - without programming knowledge
Simply create any digital forms for your group, e.g. for surveys, polls, feedback, data queries, date coordination or simply for common formal requirements of individual participants, e.g. registration forms or internal orders.
Digitising forms is an important part of a modern organisation. They regulate processes, request important data, record information and create an overview.
Video conferencing - for your group(s)
Completely integrated in mantau, a web conference can be started easily and conveniently. Whether for the whole group, simply for two, spontaneously or by creating an event as videoconference.
