What does HydraDB do?

HydraDB is a GraphDB solution built on object storage, designed to provide a cost-effective and ultra-fast foundation for modern AI workloads. It allows developers to manage and connect vast amounts of data efficiently, serving as the underlying infrastructure for various AI applications.

The platform enables the creation of ontologies, agent memory systems, and comprehensive company brains. It integrates with popular tools like Slack, Notion, GitHub, and Gmail, ingesting data to form a structured web of information. Key features include git-style temporal versioning for memory, ensuring accurate recall of data at any point in time, and robust entity resolution to prevent duplicate memory records.

Engineers and AI developers can use HydraDB to build sophisticated AI agents that operate with precise, structured knowledge rather than raw text. It is ideal for teams looking to own their memory layer, maintain data within their stack, and power AI agents at scale by providing a rich context infrastructure.
