The most important features at a glance

Single chats

Exchange conversations with one another through single or group chats. Your conversation content and files always stay in a secure environment. Your conversations take place in a setting that is inaccessible to others. In addition to #Channels, you have another opportunity to communicate with colleagues quickly and easily via stashcat®!


The #Channel feature allows you to create your own channels for each area of ​​your business. #Channels are indicated with a rhombus and can be found via the search function. The #Channel feature allows you to easily communicate with groups or teams.

File storage

At stashcat®, each user receives their own file storage in which files can be stored, retrieved and used at any time. So each user has his files always available on each connected device and can share them on request with other users or even share external links with non-members.

Not only every user, but also #Channels and conversations have their own file storage in which you can find and use stored files directly via the search function.

Internal directory

Based on the user base of your company, a directory is created - no constant availability or transfer of mobile phone numbers. If available, your organization can also be connected to an existing LDAP or Active Directory. All user accounts are displayed regularly updated in the directory.


Economic espionage, sabotage and data theft have to be taken serious, but sadly they are seen as underestimate danger of our everyday life. That's why stashcat®'s personal mission is to provide you with a data protection compliant, secure and stable communications solution. Your data and documents are transmitted end-to-end encrypted on encrypted servers across all transmission paths.

The module makes it possible to find appointments for meetings or to conduct evaluations and small surveys. The appointment inquiry as well as the question-and-answer survey can be individually integrated into the daily work routine. Users are notified directly about the creation and the results can then be exported in a PDF file.


The organization of appointments via the calendar module can be used flexibly. In addition to public and private appointments, appointments can also be shared in the channel. The module supports your daily routine with features such as the ability to accept and reject inquiries, the synchronization with the local calendar of your device and a filter system for an easy coordination of your appointments. This provides you with an overview of upcoming meetings, customer appointments or corporate events.


Upon request, we adapt logo, colors, names and appearance completely to your corporate design.
