ObsessionDB provides fully managed hosting for ClickHouse, the data warehouse software used for analytics and demanding AI workloads. Backed by Y Combinator, the company runs its service on AWS, Google Cloud, and Azure across public regions, with compute and storage separated to help maintain query speed as data grows while reducing costs. Its cache-mesh architecture keeps frequently queried data on NVMe storage, while S3 provides durable storage outside the query path.

The platform is designed for high-volume, parallel workloads, including AI agents, and offers isolated compute, detailed query logging, and usage-based compute pricing rather than per-query fees. ObsessionDB also supports MCP clients and agent tools for database and pipeline operations. Customers can access a free developer tier, request a cost audit, or use pricing tools to compare estimated costs. For production deployments, the company offers migration engineering, workload benchmarking, enterprise SLAs, point-in-time recovery, SSO and granular access controls, private networking, dedicated compute, and 24/7 support.
