ClickHouse raises $400M Series D led by Dragoneer to accelerate expansion across analytics and AI infrastructure

ClickHouse, a leader in real-time analytics and data warehousing, has announced a $400 million Series D financing led by Dragoneer Investment Group, which will support its expansion into LLM observability and the introduction of a native Postgres service. This development comes as ClickHouse experiences rapid growth, with its customer base expanding to over 3,000 and annual recurring revenue growing by more than 250% year over year. The company has acquired Langfuse, an open-source LLM observability platform, to enhance AI application monitoring, ensuring outputs are accurate and aligned with user intent. Additionally, ClickHouse has partnered with Ubicloud to offer an integrated data stack combining high-performance analytics with transactional capabilities, making it easier for developers to build AI applications. This strategic move positions ClickHouse as a unified data platform leader, capable of handling both transactional and analytical workloads, while continuing its global expansion and strengthening its ecosystem.
