LangChain was founded in 2022 as an open-source project initially created by machine learning engineer Harrison Chase. With the arrival of the AI era, the company quickly rose to prominence, solving some of the challenges in early large language model (LLM) application development, such as web search, API calls, and database interactions. In April 2023, Chase launched LangChain as a startup and successfully secured a $10 million seed funding from Benchmark. Shortly after, he completed a $25 million Series A round led by Sequoia, at which time LangChain's valuation had reached $200 million.
As the infrastructure for advanced models continues to grow, LangChain has gradually developed into a platform for building AI agents. In addition to announcing its unicorn status, the company also released updates for all its major products, including its agent-building tool LangChain, the orchestration and context/memory tool LangGraph, and the testing/observability tool LangSmith. LangChain still maintains high popularity among open-source developers, with over 118,000 stars and 194,000 forks on GitHub.
