AI agent startup LangChain hits $3B valuation

LangChain raised a $300 million Series C at a $3 billion valuation led by CapitalG, with participation from Singapore's GIC, DFJ Growth, IVP, and Sapphire Ventures, more than doubling its $1.25 billion valuation from about a year ago. The company began in 2022 as an open source project and now focuses on managing AI agents through LangSmith, which it says avoids locking users into a particular model, cloud, or ecosystem. LangChain claims 7,000 LangSmith customers, including Harvey, Rippling, Clay, Nvidia, Toyota, and Salesforce.
