Weaviate

Weaviate is an open-source vector database for building AI-native applications. It helps developers store embeddings, run semantic and hybrid search, connect data to LLMs, and build RAG systems, recommendation engines, knowledge bases, and agent workflows. The platform is useful for SaaS founders and technical teams that need retrieval infrastructure for AI products. Weaviate can be used as a managed cloud service or self-hosted depending on security, scale, and deployment needs. Its AI-native search capabilities make it a strong foundation for applications that need to find relevant context before generating answers. Developers can use Weaviate for semantic search, hybrid keyword-vector search, multimodal retrieval, generative search, and integrations with model providers and data pipelines. This makes it relevant for internal copilots, support automation, research tools, discovery products, and enterprise knowledge systems. For FutureStack, Weaviate fits the developer and founder audience because vector search is essential for serious AI products. It is best positioned as a flexible vector database for teams building production RAG, search, and AI agent systems.
