Workday VenturesIVPLangChain provides the open agent engineering platform and open source frameworks teams need to build, control and own their agent intelligence. Its commercial product, LangSmith, gives companies control over models, context and deployment for testing, debugging and observability, while its open source LangGraph gives developers low-level control to build reliable, production-grade agents; a newer harness called Deep Agents targets autonomous, long-horizon tasks.
Harrison Chase started LangChain as a side project in late 2022 and, after ChatGPT launched, co-founded the company with Ankush Gola in early 2023. Headquartered in San Francisco with offices in New York, Boston and Amsterdam, LangChain now works with 35% of the Fortune 500, has passed 1 billion open source downloads, and ingests over 1 billion events per day on LangSmith.
