Fastest scalable graph-vector database
We are building HelixDB, a database designed to combine graph and vector capabilities in one system. It stores, recalls, and enables reasoning over contextual data for AI agents replacing traditional software. Our product targets engineering, product, and design teams building AI-driven tools that need fast retrieval and complex reasoning on interconnected data.
We live in London, England, and we plan to base the company here after YC as well.
Our team and early users are in London, where we have deep context for the market and can recruit engineers familiar with databases and AI tooling.
