Announcing our $10M seed round led by Benchmark

LangChain is a framework designed to help developers build applications powered by language models, offering both Python and TypeScript packages. Initially launched as an open-source side project, LangChain has rapidly grown into a community-driven endeavor with over 350 contributors, attracting significant attention and support. It provides modular abstractions and components, such as integrations with various model providers, document loaders, and vector databases, allowing developers to build data-aware and agentic applications. Recognizing the need for further development and tooling to enhance production capabilities, LangChain recently secured $10 million in seed funding led by Benchmark to expand its offerings and support the growing community. The framework aims to simplify the creation of high-value applications by bridging the gap between prototyping and production, continuing its open-source ethos while focusing on empowering developers to innovate.
