Pendo.io is a great tool when you need to track the usage of a particular Software your company may utilize. It gives great insight into feature tracking/adoption metrics, and seems to be very flexible in terms of the features it can track. On top of feature tracking, it excels in helping establish "Guides" within your software to help your clients utilize your own tools effectively. Things like NPS tracking also become very simple when using Pendo.io. It is hard to envision scenarios where you wouldn't want to use Pendo.io, provided you're in the software business and interested in the items mentioned above. However, I was not involved in the decision-making process for using this tool, so I am not able to speak to what necessarily is/isn't possible.
