LangChain announced a $300M Series C at a $3B valuation, led by CapitalG with GIC, DFJ Growth, IVP and Sapphire Ventures participating. CEO Harrison Chase frames the thesis as "every company owning its intelligence": domain-specific agents will become standalone products and reshape internal operations, and companies controlling these systems gain lasting advantages. The commercial engine is LangSmith, a framework-agnostic platform to run, improve, and govern agents, used by 7,000+ organizations including Harvey, Rippling, NVIDIA, Toyota, and Salesforce. Clay monitors hundreds of millions of agent runs monthly on it; Workday cut new-agent deployment time from five months to under a day.
