Pinecone

Pinecone is a fully managed vector database built for AI, giving agents and applications fast, accurate retrieval where writes are instantly searchable and indexing is automatic with no tuning required. It's aimed at developers and enterprise teams building RAG pipelines and production AI apps, and it differentiates on retrieval cost and latency that stay flat as data scales — plus its Nexus layer, which compiles enterprise data into governed knowledge to cut tokens and answer in a single query. Enterprise buyers get governed access (SSO, RBAC, CMEK), compliance certifications, and uptime/support SLAs.
