Software Development Palo Alto, California 201–500 employees Founded 2021 Privately Held

ClickHouse operates a dual-revenue model: an open-source columnar database (widely deployed) and a managed cloud service (ClickHouse Cloud). The hiring mix is heavily engineering-focused (107 of 224 roles), with cloud positioning and serverless product work dominating active projects—suggesting the company is scaling its managed offering while addressing support team bottlenecks and incident-management load. Tech stack (Go, Python, C++, Kubernetes) reflects a mature infrastructure company; adoption of PostgreSQL, GCP, and Azure hints at expanding cloud-native infrastructure.
