For research & insights teams
Qualitative depth, at the scale of a survey.
Surveys scale but stay shallow; interviews go deep but don't scale. Tadeus runs hundreds of moderated voice conversations in parallel, probing, following up, and synthesising, so you get the why behind the numbers without the scheduling and transcription tax.

To fielded depth, not weeks of recruiting and calls
Synthesised
Themes out, not a transcript backlog to code
The research trade-off
Depth or scale. You shouldn't have to choose.
Qualitative research is where the real insight lives, but the method has always capped it: every interview needs a moderator, a calendar slot, and hours of analysis. So teams default to surveys and lose the why.
Interviews don't scale
A skilled moderator can only run so many sessions, so sample sizes stay small.
Scheduling kills momentum
Recruiting and calendars stretch a study over weeks before a single insight lands.
Surveys lose the why
Closed questions get the what but never the reasoning behind the answer.
Moderation drifts
Across many sessions and moderators, consistency and probing quality vary.
Analysis is the bottleneck
Transcribing and coding interviews is slow, expensive, and where insight goes to wait.
Languages cap reach
Multi-market qualitative means more local moderators and harder comparability.
How it works
A moderator that runs in parallel.
Tadeus is the interviewer. It designs depth into every conversation and runs as many as you need at once.
- 01
Design the interview guide
Set your topics, prompts, and the depth you want. Do it once, for the whole study.
- 02
Field hundreds at once
Participants complete a real moderated voice interview on their own time, in their language.
- 03
The agent probes like a moderator
It asks why, follows interesting threads, and pushes past surface answers consistently.
- 04
Synthesis happens as you go
Themes, quotes, and patterns are structured in real time, with no transcription backlog.
- 05
Read the why behind the what
Get qualitative insight at a sample size that actually moves a decision.
What the research team gets
More interviews, deeper answers.
Qualitative research without the operational ceiling: depth, scale, and speed in the same study.
Real moderated interviews
Probing, branching conversations, not a survey wearing a voice interface.
Depth at scale
Run hundreds in parallel to get qualitative insight at quantitative sample sizes.
Synthesis built in
Themes and quotes are structured as interviews complete, with no coding backlog.
Field in hours, not weeks
Skip recruiting calendars and run a full study in a fraction of the time.
Multi-market by default
Interview natively in every language with comparable output across markets.
Compliant by design
Voice only, no audio retained, no emotion inference, clear of the EU AI Act line.
Built to break the qual/quant trade-off.

Built for regulated workplaces
Compliant by design, not by disclaimer.
The EU AI Act prohibits emotion inference in the workplace from February 2025. Tadeus was built clear of that line from day one, so the hardest question an enterprise buyer asks is already answered.
No audio retained
We work from the transcript. Raw audio is never stored.
No video or faces
Voice only. No facial biometrics, nothing the camera captures.
Comprehension, not emotion
We read what was said, not feelings inferred from how it sounded.
Configurable by region
Region-gated controls so EU deployments stay clear of the AI Act line.
GDPR-aligned · We do not train models on your data · Data encrypted in transit and at rest
FAQ
Questions teams ask us first.
How does Tadeus deliver qualitative depth at scale?
It runs hundreds of moderated voice interviews in parallel, probing, following up, and synthesising in real time, so you get the why behind the numbers at survey-level sample sizes.
Is it a real interview or just a voice survey?
A real moderated interview. The agent asks why, follows interesting threads, and pushes past surface answers consistently across every session, not a fixed script with a voice interface.
How fast can we field a study?
Hours, not weeks. No recruiting calendars or scheduling, and synthesis happens as interviews complete, so there is no transcription backlog to code.
Is it compliant?
Voice only, no audio retained, and no emotion inferred from voice, clear of the EU AI Act line.
Get the why behind the numbers, at the scale you need.
