AI follow-up
“What specifically made onboarding feel easier than your previous provider?”
Human-Verified
Survey Intelligence
The depth of an interview. The scale of a survey.
Verified by humans.
Bell & Holmes Survey Intelligence goes deep on every answer. Closed-ended surveys show you the what, rarely the why. So respondents answer by voice, our system probes each one in real time, and real people verify the results before they reach you. The outcome: reliable insight into a market, a product or your customers, at survey speed and scale, in days.
Quality assurance
The hard numbers
Industry-wide, benchmarks indicate that up to 40% of survey responses get thrown away due to bots, duplicates and professional survey-takers. If that reaches your data, you decide on noise. Here is what we remove, stage by stage, before anything reaches you.
Share of responses that cannot be used
- 40%
Industry baseline
Typical post-fieldwork rejection rate across the panel industry, driven by duplicate participation, professional respondents and bot activity.
- <10%
Automated guardrails
Vetted sourcing, identity and IP checks, alongside voice detection and voiceprint analysis. Risky connections are flagged only when two independent providers agree, and same-IP duplicates are blocked outright.
- <1%
Human review
Every interview is reviewed by a person, even when the system raises no flag. A flag is a warning for the project manager, never an automatic rejection. The human decision is always the final one.
- Human-verified data, released to the case team.
Each stage is a subset of the one above it. The automated checks remove the bulk, and the human pass removes what is left.

How it works
Follow a single study end to end: respondents answer by voice, an analyst verifies and codes every response, and you receive the finished report.
Connection identity - the respondent's IP, captured server-side, for VPN/proxy and duplicate-completion checks.
Hashed, survey-scoped fingerprint that spots returning browsers, automation, or cookie-clearing retakes.
Same-survey, same-IP completions are blocked automatically and that IP is barred from future surveys.
Tab switching, leaving the window, active time in the survey, and unusually fast completions.

1. Structured questionnaire
Ratings, NPS and voice open-ends, scripted and QA'd by our team. We design the questions with you, drawing on the context you share and our experience, so each one earns its place and pulls the most from every response.
2. Voice open-ends & AI follow-up questions
Respondents answer out loud, captured and transcribed automatically. The engine probes each answer in real time for specificity and rationale. Follow-ups are driven by the brief we align on with you, not random prompts, so the AI digs into what actually matters for your decision.
3. Expert-verified output
Analysts review, then deliver a clean dataset and synthesis memo. One survey, one finished report. Three steps take a scoped questionnaire all the way to an analyst-verified dataset, usually in a matter of days.

Delivery
Verified dataset, visualizations & synthesis memo.
Every project ships analyst-verified: a clean dataset (raw & tabulated), pre-built visualizations and data maps, and a synthesis memo of the key themes.
What you get
We interviewed practitioners in consulting, private equity and corporate strategy before building this. Six things they said they need — and how you get each one.
You reach the right people
Vetted panels and identity checks put your questions in front of the actual decision-maker, and prove who answered.
You see the why, not just the score
Every open answer is spoken, then probed by AI for specifics: the reasoning behind each rating, at survey scale.
You can trust the sample
Fraud, duplicate and rushed responses are screened out and checked by an analyst, so the numbers hold up in the room.
You get it in days
Survey live within 24 hours, 200+ responses a day, topline in days. Fast enough for a deal or a launch window.
You can map the data yourself
Respondent-level data, clean crosstabs, flexible segments and visibility into fieldwork while it runs.
You get the 'so-what'
We flag anomalies, spell out the commercial implication and name the next question worth testing.
