People & Culture
Your engagement survey says 7.2. People keep leaving. Here is why.
Culture surveys systematically underestimate negative affect. Employees moderate their language when leadership behaviour is involved. EchoDepth analyses the emotional signal beneath the text — surfacing masked dissatisfaction, flagging text-emotion divergence, and producing board-ready culture health reports from data you already collect.

Employee engagement vs employee sentiment
Engagement is what employees are willing to tell you. Sentiment is what they actually feel. The gap is where retention risk hides.

The pre-exit emotional pattern surfaces in survey data 8–16 weeks before any behavioural indicator appears.

Read →The Problem with Traditional Research
Your participants are performing, not responding.
Every traditional research method puts the observer effect at its centre. The moment people know they're being studied, the data is compromised.
Traditional methods — what you get
- Social desirability bias — participants answer what they think researchers want to hear, not what they actually feel
- The articulation gap — people simply cannot accurately describe their emotional responses in words
- Post-rationalisation — conscious reflection after stimulus exposure distorts and rewrites emotional memory
- Peer pressure in groups — dominant voices suppress minority responses; groupthink contaminates qualitative data
- Recall bias — post-session surveys ask people to remember how they felt, not how they actually felt
- Geographic lock-in — facility-based research limits participant diversity and drives up cost
- No moment-to-moment data — you get a rating at the end, not a signal throughout

EchoDepth Insight — what you get instead
- Involuntary physiological signal — facial Action Units cannot be consciously controlled; they reveal genuine response
- No articulation required — VAD scores are computed from behaviour, not language
- Real-time, in-stimulus capture — emotional data is recorded at the moment of exposure, not recalled afterwards
- Individual, not group — every participant is analysed independently; no peer contamination
- Remote delivery — global participant access from any device with a camera
- Moment-to-moment timeline — see exactly when and where emotional response peaks and drops during the stimulus
- Quantified, comparable output — VAD scores enable statistical analysis, segment comparison and longitudinal tracking
How EchoDepth Insight Works
Four stages. One session. Truth throughout.
Recruit & brief
Participants join remotely via any device with a camera. Consent is captured digitally. No facility. No travel. Global access.
Expose & capture
Stimuli — concepts, packaging, messaging, video, or interview questions — are delivered in-session. EchoDepth captures 44 facial Action Units continuously throughout exposure.
Score & flag
VAD scores are computed in real time. Key moments — emotional peaks, drops, surprise signals — are automatically flagged with timestamps. Moment-to-moment emotion curves are generated per stimulus.
Report & recommend
Structured session reports with emotion timelines, group aggregates, segment comparisons and confidence scores. From insight to marketing recommendation in a single workflow.

People & Culture
EchoDepth is the people and culture intelligence platform that reveals what employees actually feel — not just what they report. Dual-layer emotional analysis surfaces masked dissatisfaction, flags text-emotion divergence, and produces board-ready culture health reports.

"The gap between what consumers say in research and what they do in market has always been the central problem of insights. EchoDepth measures the signal that language cannot — the involuntary physiological response that drives behaviour."
EchoDepth Insight does not claim to read minds. It measures Valence, Arousal and Dominance — the three quantifiable dimensions of emotional state — at the moment of stimulus exposure. Read our ethics approach →
