ClickHouse ACV Doubling With Enterprise Deployments

The main signal is that ClickHouse is not just adding logos, it is moving upmarket fast enough that each new customer is consuming much more database than the last cohort. ARR rose from about $45M at the end of 2024 to $160M at the end of 2025, while paying customers grew from over 1,000 in June 2024 to more than 3,000 by January 2026, which points to much larger workloads landing in ClickHouse Cloud as enterprises move real time analytics, logs, and AI retrieval into production.

• ClickHouse Cloud charges on usage, with storage priced per TB and compute priced per unit hour, so ACV expands when customers store more event data, run more queries, or keep bigger clusters online. That makes larger enterprise deployments show up directly as bigger contracts over time.

• The customer examples fit that pattern. AstraZeneca uses ClickHouse for petabyte scale health data and compliance sensitive AI retrieval, and a Firebolt product manager describes ClickHouse as strong for very fast, high concurrency analytics where BigQuery and Databricks become slower or more expensive for ad hoc workloads.

• This is different from Snowflake and Databricks, which are already massive platforms with broader warehouse and lakehouse scope. ClickHouse is winning narrower, latency sensitive workloads first, but the spending ramps quickly once a team routes user facing analytics, observability, or AI event streams through it.

From here, the next leg is deeper standardization inside big accounts. As ClickHouse closes enterprise feature gaps and converts more open source users to cloud, revenue should keep compounding faster than customer count, because the biggest buyers are turning it from a point solution into core infrastructure for production analytics and AI data paths.
