Lindenbaum is VIER now! The Lindenbaum GmbH in Karlsruhe has been developing its own conferencing solutions since 1999 and operates them for its customers in the Lindenbaum cloud. For our audio conferencing system with integrated application sharing (online meetings), we were awarded the Innovation Prize of the Initiative Mittelstand in 2006. Since then we have developed our platform continuously and in close cooperation with the users. The focus is on quality, ease of use and security of the conferences. Our business conferences convinced the jury of INNOVATIONSPREIS-IT of Initiative Mittelstand once again in 2017. They were awarded the title "BEST OF 2017" in the field of communication. Since 2019 we have offered our Cognitive Voice API, telephony platform and consulting services to companies wishing to integrate a voice bot into their business processes.
