What we build

Products and services from one engineering team

We provide end-to-end ClickHouse® database services and build the privacy-focused products that make data work easier.

ClickHouse® database, end to end

Architecture, migration, performance tuning, and 24/7 managed operations on infrastructure you own. We do not hand you a runbook and walk away. We run it alongside your team, from the first cluster to petabyte scale.

CHOps: our ClickHouse® admin tool

We got tired of managing the ClickHouse® database with a patchwork of tools, so we built one. CHOps brings monitoring, query profiling, backups, RBAC, and alerting into a single interface. Free, open-source, self-hosted, and zero agents on your servers.
