Vector database.

Equity grants at Weaviate typically include incentive stock options (ISOs) and non-qualified stock options (NSOs).

Bob van Luijt, Etienne Dilocker, and Micha Verhagen founded Weaviate in Amsterdam in 2019 to build a vector database designed natively for machine learning workloads rather than adapted from a relational or document store. Weaviate stores objects alongside their vector embeddings, supports multiple vectorization modules, including OpenAI, Cohere, and Hugging Face integrations, and exposes a GraphQL and REST API. The company raised a $50 million Series B in April 2023 led by Index Ventures, then a further $50 million Series C in October 2025 led by Battery Ventures.
