ClickHouse Raises $400 Million to Cement Its Position as the AI Infrastructure Foundation

ClickHouse Scales for the AI Era

ClickHouse announced the close of its 400 million dollar Series D financing round today, led by Dragoneer Investment Group. This capital injection values the company at approximately 15 billion dollars, reflecting a massive leap from its previous valuation of 6.35 billion. The funds will be used to accelerate the company’s expansion across analytics and artificial intelligence infrastructure on a global scale. In a major strategic move, the company also acquired Langfuse, an open-source platform specializing in Large Language Model observability. This allows ClickHouse to move beyond simple data storage into the realm of AI quality assurance and performance monitoring. Developers can now trace, debug, and evaluate AI applications directly within the platform to ensure accuracy and safety in production environments. To further simplify the developer experience, ClickHouse introduced a native Postgres service in partnership with Ubicloud. This integration allows teams to unify transactional and analytical workloads without the need to manage separate, disconnected database systems. By using native change data capture, users can sync data from Postgres to ClickHouse for nearly instant analytics in just a few clicks.

The company reports a period of sustained growth with its fully managed cloud service, which has seen annual recurring revenue grow more than 250 percent year over year. ClickHouse now serves a customer base that exceeds 3,000 organizations. High-profile clients such as Meta, Sony, and Tesla rely on the platform to power their most demanding, customer-facing production workloads.

Lead investor Dragoneer noted that the shift of AI from experimentation to production places immense pressure on underlying data systems. Christian Jensen, a partner at Dragoneer, remarked that value is accruing to infrastructure companies that sit closest to production. ClickHouse stands out because it delivers the performance and reliability required for AI systems operating at massive scales.

Aaron Katz, CEO of ClickHouse, stated that the additional funding combined with continued product execution positions the company to lead in the AI era. Recent advancements include enhanced support for data lakes like Apache Iceberg and full-text search capabilities for observability use cases. The company remains focused on delivering industry leading price-performance compared to traditional cloud data warehouses.
