LangChain Raises $300M at $3B Valuation

LangChain has raised $300 million in a Series C round led by CapitalG, valuing the AI agent startup at $3 billion, more than double its $1.25 billion valuation from a year ago. Founded in 2022 as an open source project, LangChain now focuses on AI agent creation and management through its LangSmith platform, which it says avoids locking users into specific models or clouds. The company claims 7,000 LangSmith customers, including Harvey, Rippling, Nvidia, Toyota, and Salesforce. Other investors in the round include GIC, DFJ Growth, IVP, and Sapphire Ventures.
