Most SaaS platforms have at least half a dozen of analytics tools to measure every single behavior. But most don't actually engage the client directly using a customer sentiment framework, like Net Promoter Score. This type of feedback is crucial for company growth.

The Net Promoter Score (NPS) is probably the best and most researched customer feedback metric.
