AI agent startup LangChain raised $300 million in a Series C round led by CapitalG, more than doubling its valuation from $1.25 billion about a year ago.
AI agent startup LangChain has raised $300 million in a Series C round at a $3 billion valuation, the company announced on Friday. CapitalG led the round, with participation from Singapore’s GIC, DFJ Growth, IVP, and Sapphire Ventures.
The valuation is more than double the $1.25 billion valuation LangChain set about a year ago, when it raised $125 million in a round led by IVP.
LangChain began in 2022 as a popular open source project that handled tasks early-stage LLMs found difficult, like searching the web, calling APIs, and interacting with databases. As frontier AI labs delivered harnesses that now competently do those tasks, LangChain turned its focus toward managing AI agents.
The startup says its agent creation and management software, LangSmith, is not trying to lock users into any particular model, cloud, or ecosystem, unlike the major clouds or frontier AI labs. It also promises that LangSmith will contain agent behavior and is easy to use.
LangChain now claims 7,000 LangSmith customers, including big-name startups like Harvey, Rippling, and Clay, and enterprises like Nvidia, Toyota, and Salesforce.
The round more than doubles LangChain’s valuation in roughly a year, underscoring heavy investment in AI agent tooling as companies move agents into production.
