Who we are
Work on ClickHouse began in 2009 with the vision of being the fastest OLAP database on earth. We are the creators of the popular open-source column-oriented database management system which allows users to generate analytical reports using SQL queries in real-time. We understand that data grows in real time and we believe that results should be fast, very fast
Mindfully distributed
ClickHouse is proud to have employees in over 10 countries. We believe that diverse and distributed workplaces working inclusively are an essential advantage. We work together to make collaboration a strength across timezone differences, languages, and cultures.
While we’re in different places, we all have the same goals, and we trust each other to do the work needed to achieve them. Being distributed isn’t a way of doing business. It’s a mindset which we leverage intentionally to build a truly global company.
