The funding round, which was led by Khosla Ventures, follows earlier investments of more than $300m, which means the total funding raised by ClickHouse is approximately $650m.

Participants in the latest funding round include new investors Bond, IVP, Battery Ventures and Bessemer Venture Partners, as well as existing investors Index Ventures, Lightspeed, GIC, Benchmark, Coatue, FirstMark and Nebius.

The funding will be used to support product development, global expansion and partnerships with customers and technology providers.

In addition to this financing, ClickHouse has secured a $100m credit facility led by Stifel and Goldman Sachs.

Aaron Katz, chief executive at ClickHouse, said: “As AI agents proliferate across data-driven applications, observability, data infrastructure and beyond, the demand for agent-facing databases like ClickHouse has reached an inflection point.

“We designed and built ClickHouse from day one to support a broad spectrum of real-time data applications across industries, and our momentum reflects that enterprises are hungry for a platform that can keep up with their scaling ambitions.”

Ethan Choi, partner at Khosla Ventures, added: “We invested in ClickHouse because they’re solving one of the most important infrastructure challenges of this era of AI and agents: enabling real-time data platforms that can support both traditional analytics and the growing demands of AI-native workloads.”
