Customer Satisfaction

You’re hearing from only 15% of your customers.
And missing what matters most.
Customers are telling you how they feel — you just can’t hear it yet.
Frustrated customers have already left. Detractors have already shared their story. Promoters have gone unrecognized. With customer survey response rates as low as 5–15%, you’re only hearing from a fraction of your customers. The rest? Invisible.


- Understand exactly how customers feel as they speak.
- Capture sentiment from every customer voice interaction, not just the 5–15% who answer surveys.
- Trigger live alerts when customer sentiment shifts mid-call.
- Map sentiment shifts to specific conversation moments (pricing discussion, hold time, problem resolution)
- Track how each agent influences customer sentiment throughout calls
