ClickHouse, a real-time analytics and database management company, has secured a $400 million Series D funding round, led by Dragoneer Investment Group, resulting in a $15 billion valuation.

The investment underscores strong demand for real-time data solutions, particularly from companies pushing into AI and large-scale analytics, positioning ClickHouse alongside competitors like Databricks and Snowflake. The firm’s recent acquisition of open-source platform Langfuse — used for monitoring large language models (LLMs) — reflects the growing importance of observability in AI workflows. ClickHouse’s technology is now widely adopted by major enterprise clients, and the valuation marks one of the most significant funding achievements in the database sector in recent years.
