We use AskNicely in Sales, Sales Support, and Marketing. It gives us a great amount of insight into our customers. We are able to segment the responses in order to see what needs to be fixed and what we need to continue to do.
If you are a subscription-based business AskNicely is a great way to see how well you are performing in the eyes of your customer before the renewal period. Any business that wants to know what customers think and how to improve should be using NPS.
