This combined funding will be used to scale product development, support global expansion, and deepen partnerships with customers and technology providers building the next wave of AI-native applications.

They join companies such as Sony, Meta, Memorial Sloan Kettering, Lyft, and Instacart, as well as AI innovators Sierra, Poolside, Weights & Bases, Langchain, and more.
“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. The future of analytics isn’t just dashboards. It’s intelligent agents that interpret data, trigger workflows, and power real-time decisions,” said Aaron Katz, CEO of ClickHouse. “But AI is just one driver. 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.”
“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,” said Ethan Choi, Partner at Khosla Ventures. “As AI reshapes every industry, the ability to deliver fast, scalable, and cost-efficient analytics is becoming foundational, ClickHouse is poised to become the default engine for next-generation intelligent data products.”
The market traction around ClickHouse is rooted in a fundamental shift: enterprises are no longer just building dashboards or batch reports—they are building real-time, intelligent data platforms that must serve both human and AI agents. Since AI agents can generate queries much faster and at a higher rate than human analysts, agent-facing databases must support low-latency, interactive analytical queries at an increasingly high throughput.
ClickHouse was designed from the ground up to meet this demand. Its high-performance, columnar storage engine enables interactive, analytical queries across massive datasets with minimal latency—perfect for powering AI and ML applications, real-time analytics, cloud data warehousing, and observability workloads.
