MoodMetrics, a UK startup founded at the University of Bath in 2024, is revolutionizing financial markets by decoding emotional undercurrents in central bank communications using its platform and Hume's Expression Measurement API. The company provides early indicators of sentiment shifts that impact financial markets through multimodal emotion analysis, including speech patterns, vocal tone, and micro-expressions. By integrating the API, MoodMetrics detects subtle emotional cues missed by traditional models, helping investment banks, retail banks, and hedge funds anticipate market movements with greater precision, resulting in a 67% prediction accuracy in a proof-of-concept following a Jerome Powell FOMC speech. The solution has been recognized through awards such as the Santander UK University Startup Grant and a Sparkies Award nomination, and its technology is becoming indispensable for competitive advantage in emotion-aware investing.
