– How many communication channels do you use every day?

Imagine a communication platform with multiple communication paths – regardless of the device you use.

– Can you trust your communication channels for security and privacy?

Do you know in which location or country your data is centrally stored and who potentially has access to your data?

– What are your past expenses when it comes to your communication platforms?

Do you know all the costs involved, including software licenses, software subscriptions, service costs and maintenance fees, etc.?

– How was your experience with your previous communication solutions during the increased requirements of the 20/21 pandemic?

Were you satisfied with the ease of use, speed, stability – and did you have a positive overall experience with all applications working together?

– How would you rate productivity in terms of communication needs?

How much time and effort is required to collect all the data from the various communication channels – as well as when using the various work tools?
