Marketing, product, and research teams can put a concept, name, price, announcement, or campaign in front of more than 100 digital twins and get open-ended answers in seconds. Listen Twins builds each one as a one-to-one model of a real person from an in-depth interview, then validates it against that person. Every response includes the twin's reasoning, a confidence score, and the interview quote behind the claim. The twins are modeled from the same kind of interviews Listen Labs already runs for brands. AI moderators recruit from a network of more than 50 million participants and conduct those conversations in more than 120 languages, for companies including Microsoft, Anthropic, and Sweetgreen. Co-founder Alfred Wahlforss, who posted the launch, described Twins as a way to check an idea with buyers before shipping it, such as whether a launch video would make them book a demo, and said it is especially useful when the audience is small or hard to reach. When a twin lacks enough signal, it says it does not know, and teams can send any finding back to real participants to check. Wahlforss and Florian Juengermann co-founded the San Francisco company in 2023 after meeting at Harvard. On September 29, 2026, Salesforce signed an agreement to acquire Listen Labs. Wahlforss said he will remain CEO and Juengermann will remain CTO, with the team continuing inside Salesforce AI Labs once the deal closes.
