Listen Labs raises $69M after viral billboard hiring stunt to scale AI customer interviews

Listen Labs secured $69 million to scale its AI-powered customer research platform that conducts video interviews and delivers insights in hours rather than weeks. The company addresses significant quality issues in traditional market research, where fraud rates can reach 20% of survey responses, by using AI to verify participant identity and detect suspicious patterns. Microsoft and other enterprise customers report dramatic time savings, though the broader promise of automated product development cycles remains largely theoretical.
