LangChain, Inc.

LangChain, Inc. is a technology company founded in 2022 by Harrison Chase and Ankush Gola, with its headquarters located in San Francisco, California. The company began as an open-source project launched by Harrison Chase in October 2022 and incorporated as a startup in 2023 to provide frameworks and platforms that support the development of applications powered by large language models. Business/Product Breakdown LangChain, Inc. provides an open-source framework that supplies pre-built agent architecture and model integrations, allowing developers to create and deploy agents with reduced coding effort. Complementing this, LangGraph offers an open-source framework with low-level primitives for constructing custom agent workflows that manage complex, stateful processes. The LangSmith Agent Engineering Platform operates independently of specific frameworks and delivers observability through tracing in TypeScript or Python SDKs to monitor agent steps and interactions. Within LangSmith, the Evaluation component facilitates the creation of test sets from production data, performance scoring via evaluators, and iterative refinement of agent outputs. The Deployment component supports one-click API-based rollout with built-in memory management, automatic scaling, and security features suited to extended agent operations.
