There’s valuable feedback about your product and your business hidden beneath the surface.

Above the water sits the easily visible feedback: metrics you’re collecting in analytics tools, NPS survey responses, customer complaints, angry Twitter rants—and hopefully a few vocal evangelists. Often, this vocal and visible group is the squeaky wheel that gets the grease and gratitude and drives change. The problem is that this type of feedback is simply the most accessible rather than representing the reality of how people feel about your product.

– Slow page load
– Too many emails
– Confusing CVS import
