ClickHouse is a tech startup that specializes in providing a high-speed, column-oriented database management system. It caters to developers and businesses that handle large-scale data, offering them a solution that is not only easy to use but also easy to manage. The company operates in the data management market, serving a diverse range of clients, including Vantage, Clearbit, and Statsig, among others.

The company's primary product is a database system that is designed to process analytical queries as quickly as possible. Unlike traditional row-oriented databases where data is stored in rows, ClickHouse uses a column-oriented approach where data from the same columns are stored together. This method is more suited to Online Analytical Processing (OLAP) scenarios, making it at least 100 times faster in processing most queries.

ClickHouse's business model is based on providing a free, open-source database system that can be deployed in any environment, whether on a local machine or in the cloud. The company also offers a fully managed ClickHouse service on Amazon Web Services (AWS), Google Cloud Platform (GCP) or Microsoft Azure, which likely serves as a revenue stream. Additionally, the company's system has been praised for its cost-effectiveness, with one client stating that moving to ClickHouse cut their bill in half.

In summary, ClickHouse is a tech startup that offers a fast, efficient, and cost-effective database management system for businesses and developers dealing with large-scale data.
