About ObsessionDB
Summary
ObsessionDB builds a fully managed, real-time data warehouse for teams running software and AI agents that generate data at high volume. It runs on a proprietary, more efficient fork of ClickHouse with compute-storage separation, keeping p99 query latency flat and cost per query falling as data scales from terabytes to petabytes. It replaces standard managed ClickHouse deployments where query costs balloon as data grows.
Business model
Usage-based pricing with a free tier and credits offered via a cost-audit conversion program.
Go-to-market
Engineering and data teams at companies with large-scale analytics workloads are the buyers; they start via a self-serve free trial or a direct founder call, with a free ClickHouse cost audit used as a top-of-funnel conversion tool.
