Pinecone — Vector Databases Platform
Vector DatabasesLayer 2FreemiumWhat is Pinecone?
Pinecone is the most widely used managed vector database, purpose-built for similarity search and retrieval-augmented generation (RAG). Founded in 2019 by Dr. Edo Liberty, former Head of Amazon AI Labs at AWS, Pinecone offers serverless and pod-based architectures supporting billions of vectors with single-digit millisecond query latency.
The platform provides metadata filtering, namespaces, and hybrid search combining dense and sparse vectors. Its managed service eliminates infrastructure complexity, making it the go-to choice for teams building semantic search, recommendation engines, and RAG-powered AI applications.
Headquartered in New York City with 138 employees, Pinecone has raised $138M in total funding including a $100M Series B at a $750M valuation. The company serves over 4,000 customers and is rated 4.7/5 on G2.

Using Pinecone with Respan
Respan complements Pinecone by providing observability into the full RAG pipeline. While Pinecone handles vector storage and retrieval, Respan monitors the quality of retrieved contexts, evaluates LLM response accuracy, and tracks end-to-end RAG performance.
- ✓Monitor RAG retrieval quality from Pinecone queries
- ✓Evaluate whether retrieved contexts improve LLM responses
- ✓Track Pinecone query latency and costs in production
- ✓Identify retrieval gaps and optimize embedding strategies
