Listen Labs has raised 69M USD in Series B funding after going viral with a billboard displaying AI tokens that led to a coding challenge. The startup uses AI to conduct customer interviews in hours instead of weeks, replacing traditional market research that takes months. Clients include Microsoft, Sweetgreen and MrBeast's company. The 500M USD valuation comes nine months after launch with revenue up 15x. https://venturebeat.com/technology/listen-labs-raises-usd69m-after-viral-billboard-hiring-stunt-to-scale-ai #AIagent #AI #GenAI #WorkforceDisruption #ListenLabs
