What Cavefish does
Cavefish Ltd is a Cardiff, Wales-based private company founded in 2023 that has built EchoDepth, a multi-modal communication intelligence platform. EchoDepth analyses video, audio, text transcripts, and images using the FACS (Facial Action Coding System) framework with a 44-Action-Unit decoder, combined with linguistic credibility mapping (hedging detection), vocal pitch/pace/hesitation analysis, and AI-generated coaching notes. Outputs include a Communication Confidence Score (0–100), per-second Credibility Signal timelines, Engagement Risk assessments, and board-ready PDF reports, with sub-200ms inference latency and on-device processing available for data-sensitive deployments.
The platform is anchored on a core multi-modal analysis engine supplemented by a suite of vertical sub-brands: EchoDepth Sales (enterprise sales coaching), EchoDepth Insight (consultancy message testing), EchoDepth Sports, EchoDepth Fintec, EchoDefence, EchoGrant, Attune, and LI Photo Score. The technology stack integrates foundation models from Anthropic, OpenAI, and Mistral, with proprietary cultural calibration across 14 cohorts in 6 countries. The company is Welsh Government backed, ICO registered (ZB915633), UK GDPR compliant, and an FCA Regulatory Sandbox participant, and has accumulated 13 industry awards since 2023.
Cavefish operates a freemium-to-enterprise commercial funnel: free sample analysis (one content submission, full scored report, no commitment) → pilot programmes from £1,500/month → enterprise software licensing with API and dashboard integration → on-premise or private cloud deployment for regulated environments. Target customer segments are enterprise sales teams, finance and investor relations functions, regulated industries (Consumer Duty evidence, audit trails), and consultancies/agencies seeking an objective evidence layer for client work. The company is very small (1–10 employees), has no disclosed revenue or institutional funding rounds, and runs primarily on Welsh Government backing and pilot-stage customer revenue.

Cavefish competitors and assessment
Company assessmentBroad incumbents
- Uniphore: Enterprise conversation AI and analytics platform covering sales, service, and compliance. Comparable to EchoDepth across sales coaching and regulated comms use cases, with broader reach and deeper enterprise penetration.
- Smart Eye (Affectiva): Acquired Affectiva to build a portfolio spanning automotive DMS, emotion AI, and media analytics. Comparable to EchoDepth in its FACS-based facial action analysis and emotion inference capabilities, but at much larger scale.
- Microsoft Dynamics 365 Sales / Viva Sales: Microsoft's enterprise CRM and sales intelligence offering, increasingly embedding conversation AI capabilities. Comparable to EchoDepth Sales as a broad incumbent that could bundle similar functionality into existing enterprise agreements.
Direct peers
- Chorus.ai (ZoomInfo): Conversation analytics that scores sales meetings and surface coaching moments. Overlaps with EchoDepth's enterprise sales coaching and discovery-call analysis use cases, with a larger installed base.
- HireVue: Video interview assessment platform using facial-expression and linguistic analysis to score candidate delivery. Strongest methodological overlap with EchoDepth's FACS-based video delivery scoring.
- Cresta: Real-time sales coaching and conversation intelligence platform. Comparable to EchoDepth in using AI to analyse delivery, sentiment, and engagement signals on customer calls.
- Gong: Conversation intelligence platform for sales teams that records, transcribes, and analyses customer calls to surface deal-risk and coaching signals. Directly comparable to EchoDepth Sales for sales-demo and discovery-call analysis use cases.
- Behavox: Communications surveillance and compliance analytics for regulated financial services, including voice, email, and chat. Directly comparable to EchoDepth's Regulated Industries use case (FCA Consumer Duty evidence, audit trails).
Emerging players
- Hume AI: Foundation models for emotional and paralinguistic understanding of voice and expression. Comparable to EchoDepth's emotion/sentiment and vocal-tract delivery analysis on a model-API basis.
- Realeyes: Emotion AI using computer vision (FACS-aligned) to score attention and emotional response in advertising and video content. Comparable to EchoDepth's FACS-based credibility and engagement scoring for message testing.
