ClickHouse, Inc. has successfully raised $350 million in Series C financing, announced on May 29, 2025, to enhance its capabilities in real-time analytics and data warehousing, bringing its total funding to over $650 million.

Notable new clients such as Anthropic, Tesla, and Mercado Libre have joined existing customers like Sony, Meta, and Instacart, showcasing ClickHouse's expanding market presence.

The announcement of the funding coincided with ClickHouse's inaugural user conference, which focused on building data products tailored to the evolving demands of AI applications.

As the market shifts from traditional dashboards to intelligent data platforms, there is a growing demand for agent-facing databases that support real-time data interpretation and decision-making.
