LangChain, a startup that builds software for creating and managing AI agents, has raised a $300 million Series C round at a valuation of $3 billion. TechCrunch reported the news, saying the company announced the funding on Friday.
CapitalG led the round. Other participants included Singapore's GIC, DFJ Growth, IVP and Sapphire Ventures, according to the report.
The new valuation is more than twice the $1.25 billion figure from about a year ago, when LangChain raised $125 million in a round led by IVP.
LangChain started in 2022 as a widely used open source project. It handled tasks that early large language models struggled with, such as searching the web, calling APIs and working with databases. As the leading AI labs began shipping their own tools that handle those jobs well, LangChain shifted its attention to managing AI agents.
Its main product in this area is LangSmith, software for building and overseeing agents. TechCrunch said the company has found traction with a straightforward pitch: businesses should be able to own their own intelligence. Because of its open source background, LangChain says LangSmith does not tie users to a particular model, cloud or ecosystem, which it presents as a contrast to the major cloud providers and frontier AI labs. The company also says the software keeps agent behavior contained and is easy to use.
The market is crowded. TechCrunch noted that many other startups make similar claims and are also doing well, and it pointed to the newcomer Mintive as one example. LangChain, however, had a head start.
The company now says it has 7,000 LangSmith customers. They include startups such as Harvey, Rippling and Clay, as well as large enterprises such as Nvidia, Toyota and Salesforce.
