Data analytics company ClickHouse has raised $400 million in a Series D funding round led by Dragoneer Investment Group, reaching a valuation of $15 billion. The new funding more than doubles its previous valuation and highlights growing investor interest in infrastructure that supports artificial intelligence applications. Participants in the round also included Bessemer Venture Partners, GIC, Index Ventures, and others.

The financing positions ClickHouse to better compete with established rivals like Snowflake and Databricks in the real-time data analytics and cloud data warehouse market. The company, which develops high-performance database software, has seen its annual recurring revenue grow over 250% year-over-year and serves more than 3,000 cloud customers, including Meta, Sony, and Tesla. Alongside the funding, ClickHouse also announced its acquisition of Langfuse, an open-source LLM observability platform.
