LangChain Hits $3B Valuation on $300M Series C Led by CapitalG

Agent management startup LangChain has raised a $300 million Series C at a $3 billion valuation, with CapitalG leading and Singapore's GIC, DFJ Growth, IVP, and Sapphire Ventures participating, TechCrunch reported Friday.

The number the piece underlines is the step-up. The new valuation is "more than double its $1.25 billion valuation" from roughly a year earlier, when the company raised $125 million.

LangChain's primary product is LangSmith, which TechCrunch calls agent creation and management software built on a vendor-neutral approach, one that "avoids locking users into particular models, clouds, or ecosystems." The company reports 7,000 LangSmith customers, naming Harvey, Rippling, and Clay among startups, with Nvidia, Toyota, and Salesforce on the enterprise side.

LangChain started in 2022 as an open-source initiative aimed at the limits of early large language models: web searches, API calls, database interactions. As model capabilities advanced, the product moved up a layer, toward managing the agents sitting on top.

It lands amid a long run of funding alerts, 441 of which we have tracked in the last 90 days.
