ClickHouse, a real-time analytics and data warehousing company, announced that it has raised $400 million in Series D financing led by Dragoneer Investment Group, with participation from several major institutional and venture investors. Founded in 2012, the company provides a high-performance platform used for analytics, observability, and AI-driven workloads.
The financing follows strong growth in ClickHouse Cloud and has reported over 250% year-over-year ARR growth. Recent customer adoption and expansions include Capital One, Airwallex, Polymarket, and Decagon, adding to an existing base that includes Meta, Sony, and Tesla. “ClickHouse was built to deliver exceptional performance and cost efficiency for the most demanding data workloads, and this momentum validates that strategy,” said Aaron Katz, CEO of ClickHouse.
The funding coincides with major product and strategic developments. ClickHouse announced the acquisition of Langfuse, an open-source LLM observability platform, and introduced an integrated enterprise Postgres service designed for unified transactional and analytical workloads.
Christian Jensen, Partner at Dragoneer Investment Group, said that ClickHouse offers the performance, operational efficiency, and dependable infrastructure necessary for large-scale AI deployments. Marc Klingen, CEO of Langfuse, added, “Now, as one team, we can deliver a tighter end-to-end product, from faster ingestion to deeper evaluation.”
