LlamaIndex, founded in 2023, builds tools for developers and enterprises to create AI agents that work with documents. Its core offering combines an open-source SDK with LlamaParse, an enterprise-grade platform for document parsing, extraction, reasoning, and automation. The company was founded by former Uber research scientists and is backed by Greylock.
The LlamaIndex SDK enables developers to build intelligent agents capable of reading and reasoning over complex documents, adapting to business logic, and scaling to production environments. LlamaAgents extends this into end-to-end document-centric workflows, covering ingestion, extraction, reasoning, and automation. Together, these products support use cases ranging from low-code workflow design to production-scale deployments. The SDK contributes to over 25 million monthly package downloads across the company's products, and LlamaParse has accumulated more than 300,000 users.
LlamaIndex's customer base spans fast-growing AI companies and Fortune 50 enterprises, reflecting a dual focus on developer adoption through open-source tooling and enterprise readiness through its commercial platform. The company's stated mission is to automate knowledge work, beginning with documents.
