San Francisco-based ClickHouse, an open-source columnar database company, has raised $400 million in a new funding round led by Dragoneer Investment Group, with participation from Bessemer Venture Partners, GIC, Index Ventures and Khosla Ventures, among others.
In a news release on Friday, ClickHouse announced it now serves more than 3,000 customers through its managed offering, ClickHouse Cloud. CEO Aaron Katz said the new funding will support the development of unified transactional and analytical workloads, enabling developers to build AI-powered applications on a more robust and scalable data platform.
The funding will also allow ClickHouse to expand into large language model observability, giving AI application developers tools to assess the quality, performance and behavior of AI outputs as they move systems into production.
Alongside the new funding, ClickHouse announced its acquisition of Langfuse, an open-source LLM observability platform, as it continues to expand its global presence. Over the past year, ClickHouse has hosted user events across the United States and internationally in cities including Amsterdam, Sydney and Bengaluru.
