Until now, visitors to public events who wanted to stay up to date had to gather the necessary information from a wide variety of sources; providers had to go to great lengths to communicate dates and possible changes. The Wiesbaden-based start-up Calovo now offers the first portal for creating and publishing dynamic calendars and event series. For example, a Bundesliga club can use it to provide its fans with an up-to-date match schedule at all times. In addition to the dates, further information or links can also be integrated.
