Cavefish — the AI sales coaching company behind EchoDepth.
Cavefish was founded on a single conviction: that emotional presence is the most underused competitive advantage in business — and the most undertrained skill in sales.
Most sales training ignores
the most important variable.
Sales performance research consistently shows that how a rep shows up emotionally — their presence, their composure under pressure, their ability to read a room — determines outcomes more than product knowledge, pricing, or process.
Yet every sales training programme focuses on what to say. Scripts, frameworks, methodologies. None of it trains how to say it. None of it measures whether it lands.
emotional intelligence is the ability to recognise, measure, and deliberately control the emotional signals that influence how decisions are made — in sales, in security, in sport, and across every domain where human judgement determines outcomes.
Cavefish was founded in Cardiff, Wales, in 2023 to close that gap. We built EchoDepth — a multimodal emotion AI platform — to give individuals and organisations objective insight into their emotional impact, and a system for training it.
EchoDepth for Sales is the commercial application of that platform: avatar-led coaching that trains the human side of selling, backed by EchoDepth developed across 13 award-winning applications in finance, defence, sport, and enterprise.
We're currently in early access programme, working with a select group of enterprise sales teams. Request access to join the programme. The results are driving our roadmap.
Powered by EchoDepth
Multimodal emotion AI trained across 6 countries, 14 cultures, and 44 facial Action Units — mapping to VAD (Valence, Arousal, Dominance) in real time.
Principles we build on.
Emotion is trainable
Emotional control is a learnable skill, not a personality trait. With the right feedback loop, anyone can learn to manage their presence deliberately.
Authentic beats performed
Reps who try to fake confidence get detected — by humans and by our system. EchoDepth rewards genuine emotional access, not surface performance.
Objective over anecdotal
Sales coaching has always relied on manager gut feel. EchoDepth gives teams the objective, timestamped emotional data that makes coaching consistent and scalable.
Privacy by design
Session data is used for coaching only. We don't identify, surveil, or store biometric profiles. Reps control their own improvement journey.
Bias-resistant AI
Our models are trained across 6 countries and 14 cultures. Emotional expression varies across backgrounds — EchoDepth is built to work equitably.
