Benefits of TenFour

Content Management

Content is at the heart of your presentation, marketing or advertising projects. That is exactly why we built TenFour around content. The popular intuitive user interface of the Content Management System can be fully customised to your wished and requirements, thus allowing you to quickly modify or create contributions or presentations even when the hustle and bustle of your daily routine are at its peak. TenFour’s modular structure allows you to add or remove functions or modules. With TenFour you are perfectly flexible and independent – now as well as in the future.

Present and entertain

Apart from the time-tested Content Management System, the individual modules are at the core of TenFour. They present your visitors, guests and customers the content of your choice at a predetermined time. You decide in advance or even spontaneously which content is to be shown on which screen. The content may range from product presentations via live video to votings and games. Of course, we continue developing new modules all the time that integrate the latest social media trends or improve the presentation of your products and services.

Content everywhere

Presentation and Content Management Systems are often bulky and inflexible. We have been aiming at showing you the widest range possible of functions with regard to your content. TenFour allows you, for example, to load your indoor screens, your website and your online shop – all from one system and with a single maintenance effort. Apart from the broad social media integration that monitors your channels and searches any given channel for search tags, TenFour also allows you to share your content in almost all social networks.

We love software, especially if it works well. But even after the successful completion of many projects, our customers were often left with the desire to be able to edit elements and add content themselves. Systems that meet these requirements have been around since the 1990s, but programming them is far more complex than most people think.

TenFour had its baptism of fire in the studios of the German TV station ARD, which are known for their high technological standards. For this project further features were added to TenFour until the current level of performance was reached. Due to the resulting range of functions TenFour can be used in the most varied fields. Be it broadcast or shopping mall, with TenFour operation and data management of each installation are as easy as pie and ensure independent working.

This is the reason why we developed something that ideally takes our customers‘ needs into consideration – our content tool TenFour, whose name stands for successful communication. Our Content Management System can handle the most varied visual output devices and the modules can be expanded incrementally thus increasing the customers‘ independence.
