About Weaviate
Weaviate is a Dutch-founded, open-source vector database designed specifically for AI-native applications. It allows developers to store data objects and vector embeddings from their favorite ML-models, and scale seamlessly to billions of data objects. The platform operates as a core infrastructure component for Retrieval Augmented Generation (RAG), enabling AI models to access proprietary and real-time data securely. The service is unique in its deployment flexibility, offering a managed SaaS (Weaviate Cloud), a serverless consumption model, and a robust self-hosted option for organizations with strict data sovereignty requirements. Its architecture combines vector search capabilities with structured filtering, providing a hybrid search experience that is critical for enterprise use cases in fintech, healthcare, and e-commerce. As an open-source project, it provides high transparency and prevents vendor lock-in.
