Talk to thousands.
By Tuesday.
Voice CSAT, NPS, and qualitative research at the scale of email surveys — with response rates closer to a live interviewer. Branching questions, full verbatims, structured outputs.
Email surveys are dying.
Voice surveys aren't.
Voice gets answers email forms don't — open-text quality, real sentiment, the casual “honestly, the thing that bugged me…” you'll never read on a form.
Higher response rates
Email CSAT typically lands around 8%. Voice surveys tend to land far higher — closer to a live interviewer than a form.
Richer open-text
People say more than they type. Spoken verbatims are usually longer and more candid than anything you read on a form.
Branching logic
Promoters get one follow-up, detractors get a different one. No “if you said no, please answer…”
Real-time analysis
Themes auto-clustered as responses arrive. You don't wait for a research deliverable.
Theme analysis
that doesn't wait for Monday.
We cluster verbatims into themes in real time and hand them over through post-call analytics. The first 100 calls give you the headline; the first 1,000 give you statistical confidence.
Programs Convexa
customers run monthly.
From post-interaction CSAT to longitudinal panels, our team designs and manages every kind of voice research programme — including healthcare outcome panels and insurance claim follow-ups — so your insights team gets results, not a tool to run.
CSAT after every call
90-second voice survey within 4 hours of close. Branching follow-ups by NPS score, themes clustered live.
Relationship NPS
Quarterly NPS to your customer base. Three-question survey: score, reason, top-of-mind improvement.
Patient outcome panels
Recurring 4-week voice check-ins for patients on a new treatment. Structured outcomes + qualitative verbatim.
Sales win-loss interviews
Convexa calls lost-deal prospects 7 days post-close, asks why, attributes themes back into your CRM.
Concept testing & pricing
Read a one-sentence concept, capture open response, ask three structured probes. 200 responses overnight.
Employee pulse
Inbound number employees can call to leave a 60-second voice memo. Themes surface anonymously.
“A quarterly NPS that used to be a six-week project now ships in days — and the verbatims are richer.”
Pair it with these.
