Investment Thesis
Listen Labs uses AI to conduct thousands of voice-based customer interviews simultaneously, transforming how companies do market research and gather product insights. The platform automates qualitative research at quantitative scale, giving product and strategy teams deep customer understanding in hours instead of weeks.
Founded in 2023 by Alfred Wahlforss and Florian Juengermann, Listen Labs raised $27M across its seed and Series A rounds led by Sequoia's Bryan Schreier. The company subsequently raised a $69M Series B in January 2026 led by Ribbit Capital, bringing total funding to approximately $100M.
Traditional market research through surveys and focus groups is slow, expensive, and plagued by low response rates and self-reporting bias, leaving product teams making decisions on stale or shallow insights.
Listen Labs uses AI-moderated voice interviews at scale, conducting thousands of natural conversations simultaneously to extract qualitative depth at quantitative scale — something that was physically impossible before.
Brands spend $80B+ annually on market research and are desperate for faster, richer signal; Listen Labs collapses weeks of fieldwork into hours while capturing emotional nuance that surveys miss entirely.
Conversational AI has crossed the uncanny valley for conducting natural-sounding interviews, and enterprises are under intense pressure to shorten product development cycles with real customer voice data.
