Agent-managed startup LangChain has raised $300 million in Series C at a $3 billion valuation led by CapitalG, with participation from investors including Singapore’s GIC, DFJ Growth, IVP, and Sapphire Ventures, the company announced on Friday.
This is more than double the $1.25 billion valuation it received when it raised $125 million led by IVP about a year ago.
LangChain started in 2022 as a popular open source project that handles the kinds of tasks that early-stage LLMs found difficult, such as searching the web, calling APIs, and interacting with databases. LangChain shifted its focus to managing AI agents as Frontier AI Labs provided a harness that could successfully perform these tasks. The company seems to have made a breakthrough in this competitive field with a simple message: let businesses own their own intelligence.
The company, which has open source roots, says its agent creation and management software, LangSmith, doesn’t try to lock users into a particular model, cloud, or ecosystem, unlike the big clouds and Frontier AI Labs. LangSmith also includes agent behavior and promises to be easy to use.
To be sure, there are plenty of other successful startups touting similar benefits these days (newcomer Mintive being a great example). But LangChain has had a head start and now claims to have 7,000 LangSmith customers, including major startups like Harvey, Ripling, and Clay, as well as companies like Nvidia, Toyota, and Salesforce.
