LangChain has raised a $300 million Series C funding round led by CapitalG. The funding values the AI agent software company at $3 billion.
LangChain’s funding round also includes GIC, DFJ Growth, IVP and Sapphire Ventures. The company plans to expand its workforce, improve infrastructure and grow its engineering, sales and marketing teams.
LangChain began as an open-source project in 2022, helping large language models search the web, call APIs and interact with databases. It has since shifted its focus towards managing AI agents. Its paid LangSmith platform lets developers test agents, track performance and find faults after deployment.
LangChain says LangSmith has 7,000 customers, including Harvey, Rippling, Nvidia and Toyota. LangChain also says it is not trying to lock users into a particular model, cloud or ecosystem. For companies building with AI, that makes provider choice a central part of its pitch, alongside the tools needed to keep agents working after launch.
The committed funding gives builders a better-capitalised supplier for AI agent development and management tools.
LangSmith’s testing and monitoring features show why builders must select tools for ongoing operation, not just initial agent development.
LangChain’s stated intention to avoid lock-in is relevant to teams concerned about provider dependence, but does not establish technical portability or freedom from lock-in.
