What LanceDB Does

LanceDB is a San Francisco-based database company founded in late 2021 by Chang She and Lei Xu that builds an open-source vector database and multimodal lakehouse for AI workloads. Its engine is built on the Lance columnar format, designed to store and query vectors alongside the images, video, audio, and documents they were computed from, so teams can run search, analytics, and training data workflows on one system.

LanceDB is a Y Combinator alumnus and raised a $30 million Series A led by Theory Ventures — with participation from CRV, Databricks Ventures, and Runway — bringing total funding to roughly $41 million. The open-source project is widely used as an embedded, serverless alternative to managed vector database services.
