Together. Easy. Organised. mantau!
Common tasks, projects, goals or interests bring people together. Whether in companies, organisations, authorities, associations or groups of private individuals. Wherever groups come together to get things moving, well-functioning communication and smart organisation are required.
This is exactly why we developed the collaboration app mantau, a combination of messenger, secure cloud storage, shared scheduler, universal form & digitalisation tool - and more. Groups, subgroups and roles provide an overview and, as a multi-platform, mantau enables hybrid working. Simple, efficient from anywhere via phone, tablet or laptop. Ideal for collaborative work, ideal for exchanging, coordinating, documenting and saving data and knowledge.
mantau gives every organisation a bright and secure future: perfect collaboration, cohesion and healthy commitment.

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, create serial dates - and all events clearly organised in a shared - yet personal - calendar. And thanks to calendar synchronisation, everything can be brought together.
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.
Ideal addition to e.g. e-mail or WhatsApp groups! If you don't want to move your group to mantau right away, you can share links to files and folders in mantau.
Form & digitization tool for groups
Simply create any digital forms for your groups - without any programming knowledge - e.g. for surveys, polls, appointment scheduling or simply for standard formal requirements, e.g. registration or order forms.
Ideal for efficient collaboration in groups and the digitalization of workflows and processes - especially in larger organizations.
Tip! Also a good addition to email or WhatsApp groups: Simply create mantau forms and share the direct links via these media or chat groups.
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.
