ClickHouse, Inc. develops ClickHouse, an open-source columnar database for real-time analytics, engineered for millisecond queries on billions of rows.
ClickHouse, Inc. builds ClickHouse, an open-source columnar database for real-time analytics. The system is engineered for extreme query performance on fresh data, with infrastructure that processes billions of rows in milliseconds. Engineering trade-offs are made at a fine grain: the company describes its optimisations as measured in bytes and nanoseconds, in order to save petabytes of storage and seconds of query time.
The work spans columnar database internals, real-time analytics, data analytics infrastructure, query optimisation and open-source software development. ClickHouse serves the broader data analytics and database infrastructure fields, where speed and accessibility of data are treated as foundational requirements. Engineers and open-source contributors work on pushing performance boundaries under tight constraints, with an emphasis on practical problem-solving.
ClickHouse, Inc. is a distributed organisation. The team is spread across more than 10 countries, and the company treats timezone differences as a strength rather than a limitation. Diverse perspectives are seen as a driver of innovation, and the operating model rests on a high-trust culture in which people are relied upon to do the work needed to achieve shared goals.
