ClickHouse is a privately owned company headquartered in the US. Founded in 2021, the company has approximately 130 employees. Functioning as a software development firm, ClickHouse developed an open-source column-oriented database management system for online analytical processing, allowing users to generate analytical reports using SQL queries in real-time.
ClickHouse recently introduced a new solution accelerator for media publishers on March 12, 2026, enabling real-time editorial analytics in conjunction with Snowplow, offering a faster alternative to traditional overnight reporting stacks. On the same day, the company detailed its robust capabilities for parsing various date and datetime formats, including Unix timestamps, numeric dates, and ISO 8601 strings, and explained the Time to Live (TTL) feature, which provides granular control over data lifecycles for automatic record deletion, historical data aggregation, and sensitive field anonymization. Earlier on March 12, the "What's new in ClickStack. February '26" update highlighted the external API for ClickHouse Cloud, which has become essential for enterprises managing dashboards and alerts at scale and has been available in open source. This followed a March 11 session detailing the new inverted index mechanism, designed to significantly improve the performance of full-text search queries in production workloads by complementing existing skipping index mechanisms.
