LlamaIndex is a data framework company founded in 2022 that specializes in connecting large language models to external data sources. The platform enables developers to build retrieval-augmented generation (RAG) applications by indexing, retrieving, and augmenting prompts with relevant documents, databases, and APIs. LlamaIndex provides tools for data ingestion, indexing strategies, and query engines that optimize how LLMs access and process enterprise information. The company's core offering addresses a fundamental limitation of large language models: their training data cutoff and inability to access real-time or proprietary information. LlamaIndex abstracts away the complexity of data integration, offering pre-built connectors to various data sources and multiple retrieval strategies to improve answer relevance and accuracy. Positioned within the broader AI agents and LLM infrastructure category, LlamaIndex competes alongside other data-to-LLM frameworks like LangChain and vector database providers. The platform has gained adoption among developers building enterprise AI applications, particularly those requiring grounding in external knowledge bases. The company has raised $28M in total funding and is currently at Series A stage, with a valuation of Not disclosed. Since its 2022 founding, LlamaIndex has experienced rapid adoption within the RAG application development community, reflecting growing demand for production-grade tools that integrate large language models with enterprise data. LlamaIndex solves the critical problem of efficiently connecting LLMs to external data sources through purpose-built indexing and retrieval infrastructure.
