Key features	Ontology-powered knowledge graphs built from a company's own documents Stated 30%+ accuracy improvement over vector-based RAG on complex knowledge Perseus generates production-ready ontologies from domain data in minutes Built for compliance and traceability in regulated industries Business experts kept in the loop during graph generation	Open-source vector database, free to self-host with full source access Qdrant Cloud managed service with a free tier and usage-based paid plans Purpose-built for semantic search, recommendations, and RAG pipelines $50M Series B raised March 2026 to expand agent-retrieval infrastructure Filterable vector search with payload metadata alongside embeddings
Pros	Traceability and auditability matter for AI used in regulated industries Perseus meaningfully speeds up what is normally a months-long ontology project A named, checkable enterprise case study rather than only a claim	Open-source option gives full control and zero licensing cost for self-hosted deployments Managed cloud tier removes the operational overhead of running vector search infrastructure Free tier on Qdrant Cloud is generous enough for real prototyping, not just a demo
Cons	No public pricing; every engagement starts with a demo or trial request Requires a real implementation project, not a plug-and-play setup Overkill for a small team with a basic internal search need	Self-hosting still requires infrastructure expertise the managed tier is meant to remove Competes in a crowded vector-database field against Pinecone and several open-source alternatives Newer funding means less operating history than some competing vector databases
Company	Lettria, founded 2019	Qdrant, founded 2021
