According to LangChain Blog:

LangChain announced that it has raised $300 million in Series C funding at a valuation of $3 billion, led by CapitalG with participation from GIC, DFJ Growth, IVP, and Sapphire Ventures. The company believes that AI agents will transform the economy, and every enterprise will need to control its own intelligence, data, and infrastructure to build competitive advantages.

To capture this market, LangChain highlights its LangSmith platform, which serves over 7,000 organizations—including Fortune 500 enterprises like NVIDIA and Toyota as well as startups like Harvey. LangSmith is structured around three core pillars: Agent Runtime (infrastructure and architecture for running agents), Agent Improvement (testing, monitoring, and automated optimization), and Agent Governance (centralized control over models, tools, and sensitive data). The company also announced an upcoming release event scheduled for Friday, November 20th, to introduce new platform capabilities.
