The company, based in San Francisco, uses an ‘AI interviewer tool’ to survey participants, and then creates reports, themes, highlight reels and decks.

Ribbit Capital led the Series B funding round, with participation from Evantic and existing investors Sequoia Capital, Conviction and Pear VC. The financing adds to the $27m the company raised in its Series A in 2025.

To date, the platform has interviewed over one million people, with interviews based on a panel of around 30 million people, according to the company.

Listen Labs was founded by Florian Juengermann and Alfred Wahlforss, who worked together to develop an AI avatar app when they were students at Harvard University.

Microsoft, AI software Perplexity and restaurant chain Sweetgreen are among Listen Labs’ customers. Jonathan Neman, chief executive at Sweetgreen, said the brand has used Listen to identify insights on customers’ struggle to consume enough protein daily. Neman said: "That insight has inspired us to create more protein-forward menu options, like the Protein Bowl, and continues to guide how we test future offerings."

Alfred Wahlforss, co-founder and chief executive, Listen Labs, said: "Teams that use Listen bring the customer into every decision, from marketing to product."
