LlamaIndex's open-source data framework has 30M+ downloads and its LlamaCloud platform provides managed data pipelines for enterprise RAG, raising $18M with backing from Sequoia and Jerry Liu as founder.
LlamaIndex provides the data layer for LLM applications — a set of tools for ingesting, structuring, and querying data as context for AI models. Its open-source library has become the standard for building RAG pipelines, with abstractions for document loading, chunking, embedding, and retrieval that integrate with 160+ data sources and all major vector databases. LlamaIndex is complementary to LangChain, focusing on data connectivity while LangChain focuses on agent orchestration.
