ClickHouse – a leader in real-time analytics, data warehousing, observability, and AI/ML – announced it has raised $350 million in Series C funding. The funding round was led by Khosla Ventures, with participation from new investors BOND, IVP, Battery Ventures, and Bessemer Venture Partners, as well as existing investors including Index Ventures, Lightspeed, GIC, Benchmark, Coatue, FirstMark, and Nebius.
This funding round follows earlier investments of over $300 million, bringing total funding to over $650 million.
The market traction around ClickHouse is based on a fundamental shift as 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. And 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 built from the ground up to meet this demand. And its columnar storage engine enables interactive, analytical queries across massive datasets with minimal latency, which works well for powering AI and ML applications, real-time analytics, cloud data warehousing, and observability workloads.
How the funding will be used: This 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. Along with the financing, ClickHouse has secured a $100 million credit facility led by Stifel and Goldman Sachs.
Momentum: The company has grown by over 300% in the past year and now serves more than 2,000 customers across various industries, including fintech, transportation, consumer, and healthcare. And new customers include Anthropic, Tesla, and Argentina’s Mercado Libre, among others. They join companies like Sony, Meta, Memorial Sloan Kettering, Lyft, and Instacart, as well as AI innovators Sierra, Poolside, Weights & Bases, Langchain, and more.
KEY QUOTES:
“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. 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.”

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.”
