One Question, One Number
Ask customers one question, on a scale from 0 to 10, and NPS turns their answers into one score. Companies subtract the detractors from the promoters and call the result a strategy.
The question is fast to ask and easy to track over time. That is also its limit. A single number cannot hold a complaint, a compliment, and a competitor’s name at the same time. It holds none of them. It holds an average.
What the Research Actually Shows
Frederick Reichheld introduced Net Promoter Score in a 2003 Harvard Business Review article, arguing it predicted revenue growth better than any other metric available.
Four years later, a team of academics tested that claim directly. Timothy Keiningham, Bruce Cooil, Tor Andreassen, and Lerzan Aksoy ran a longitudinal study across multiple industries and published it in the Journal of Marketing.
This does not mean NPS is worthless. Tracking it over time still shows direction. It means the number alone was never the whole picture, and the research says so in writing.
The Comment Nobody Reads
Most NPS surveys include one open text box: “Why did you give that score?” Few companies read every response. Fewer still process them at scale.
That box is where the real signal lives. A detractor’s comment names the exact feature that failed them. A promoter’s comment names the exact reason they stayed. A comment that names a competitor by name is worth more than the score attached to it.
Summarizing that text by hand does not scale past a few hundred responses. Most companies stop reading long before they should.
What a Sentiment Read Adds
Active Pulse reads the same open-ended feedback, support tickets, and reviews your team already collects. It organizes that text into six dimensions instead of one number: product quality perception, customer support experience, price and value perception, brand trust, competitive differentiation, and advocacy signals.
Six numbers instead of one is not the real change. The real change is that each dimension comes with the themes behind it: named pain points, named competitors, and which way each trend is moving.
Where This Falls Short
No system replaces a real conversation between an operator and a customer. A sentiment read tells you where to look. It does not replace the follow-up call.
Themes pulled from text also depend on the volume and honesty of what customers actually wrote. A support queue with ten tickets will not surface a reliable trend. A survey built around a leading question will not either.
