Listen Labs walks from $1.5 billion round amid Salesforce talks

Listen Labs was co-founded in 2023 by Florian Jüngermann and Alfred Wahlforss, who met while pursuing master's degrees at Harvard. The startup uses voice AI to conduct customer interviews, developing survey questions and packaging the resulting conversations into reports and PowerPoint presentations, similar to traditional human market research. Fortune 500 companies rely on such research to gauge customer needs, but traditional methods are expensive and can take weeks. Listen Labs' technology aims to reduce that time and cost.

The startup's customers include Microsoft, Canva, Anthropic, and Sweetgreen. It competes with Simile, Outset, Keplar, and Aaru. Simile, which predicts human behavior, closed a $200 million Series B at a $2 billion valuation led by Greenoaks in late July, likely setting a benchmark for Listen Labs. Listen Labs was previously valued at $500 million when it announced a $69 million Series B in late January.

Whether Salesforce proceeds with an acquisition may hinge on its willingness to pay a 67-times revenue multiple, which one person with exit experience called potentially too steep. If talks collapse, Listen Labs could return to market targeting $2 billion or higher, according to several VCs. The outcome may shape how AI research startups weigh acquisition interest against venture funding.
