After Valuation Talks in May, ClickHouse Lands $350 Million at $6.35 Billion

ClickHouse has spent the last decade optimizing for speed. That focus on performance, not extensibility has made it one of the most widely adopted systems for real-time analytical workloads. Now, it’s also one of the most highly valued.

After reports in May that it was in advanced talks to raise capital at a $6 billion valuation, ClickHouse has now confirmed a $350 million Series C at a valuation of $6.35 billion. The round was led by Khosla Ventures, with participation from BOND, Battery Ventures, Bessemer Venture Partners, and IVP, alongside existing investors Index Ventures, Lightspeed, Benchmark, Coatue, FirstMark, Nebius, and GIC. It also secured a $100 million credit facility from Stifel and Goldman Sachs, bringing total funding to more than $650 million.

ClickHouse, the column-oriented database, originally developed at Yandex in 2009, was built to solve a clear problem on how to process complex analytical queries at high speed, across massive datasets, without unnecessary overhead. It remained focused on that core for more than a decade. Then, as companies began turning to real-time telemetry, observability, and machine-driven systems, ClickHouse became the kind of infrastructure that more teams realized they needed.

The company says the capital will be used to scale its cloud product, expand global operations, and strengthen customer partnerships. It has also begun to grow its capabilities through acquisition, adding HyperDX, focused on observability, and PeerDB, which replicates Postgres data into ClickHouse with minimal latency.
