About HelixDB
Summary
HelixDB builds a combined graph and vector database that gives AI agents persistent memory, connected knowledge, and grounded retrieval in a single system. It replaces the patchwork of separate vector stores, graph databases, and search indexes that developers otherwise stitch together to support agent workflows. Customers range from dev-tool teams linking code, docs, and incidents to enterprises grounding AI answers in permissioned company records.
Business model
A free tier plus paid enterprise plans.
Go-to-market
Developer teams and enterprises adopt HelixDB directly, with a self-serve sign-up path and a separate enterprise track for larger deployments.

The fastest & most scalable graph-vector database on the market
As AI agents replace traditional software, they need a way to store, recall, and reason over contextual data. HelixDB gives them all of that in one system. We’re building the knowledge infrastructure every AI agent will depend on.
