On May 27, 2026, ClickHouse, Inc. opened its second annual user conference, "Open House 2026", showcasing remarkable advancements and growth within the company. This quarter has been pivotal, highlighted by a series of announcements that underscore ClickHouse's rapidly expanding influence in the data analytics landscape.
One of the most impressive achievements is ClickHouse's annual recurring revenue (ARR), which has skyrocketed more than threefold from the previous year, reaching over $250 million. Since January 2026, the company has acquired more than 1,000 new customers, bringing the total client base to over 4,000.
Prominent among the new and expanding users are noted industry players like Anthropic, Meta, Cursor, Sony, Tesla, as well as newcomers such as Capital One and Lovable. The widespread adoption of ClickHouse by major enterprises like Visa, Cisco, and Shopify highlights its role as a foundational element in modern data architecture.
Aaron Katz, CEO of ClickHouse, emphasized that the recent surge in demand for high-performance and cost-effective AI processing is evident. The growth from 3,000 customers in January to over 4,000 within just one quarter signals that the evolution in data infrastructure isn't a fleeting trend, but rather a transformative shift in how businesses leverage data. The announcements made during this week are designed to solidify ClickHouse's competitive edge as AI transitions from experimental phases to mainstream operations.
Launch of ClickHouse Agents with Claude Integration
In a significant move toward integrating AI into data analytics, ClickHouse introduced "ClickHouse Agents", a fully managed analytical service supported by Anthropic's Claude. This innovative no-code agent builder allows any user to easily define, construct, and deploy AI agents based on ClickHouse data.
These agents come equipped with essential features such as a chat interface, a sandboxed code interpreter, shared artifacts, skill management, memory functions, and multi-agent workflows. Additionally, ClickHouse Agents naturally integrate with third-party systems and AWS Agent Registry, empowering organizations to utilize their data comprehensively.
ClickHouse is also investing in other AI-oriented products, including Managed Postgres, which seamlessly ties ClickHouse’s analytics capabilities with transaction state management, thus facilitating high throughput analytics for AI applications. Moreover, Managed ClickStack, an observability service to monitor infrastructure and model training, is now fully managed, providing greater accuracy and tracking capabilities for AI agent outputs.
Introduction of CostBench Benchmarking Tool
To help clients navigate the intricate landscape of AI workloads that demand high concurrency and low latency, ClickHouse has launched "CostBench," an open benchmarking tool. This enables businesses to directly compare actual computation pricing models across various vendors applied to the same analytical workloads. The benchmarking results have shown ClickHouse Cloud to maintain "high-speed and low-cost" performance across diverse data scales, significantly outperforming close competitors.
Launch of Official Partner Program "House Mates"
In a bid to strengthen its ecosystem, ClickHouse announced the launch of its inaugural official partner program, "House Mates." This program includes over 25 tech partners and more than 35 service/channel partners from six continents. The new community will offer built-in integration environments and proven implementation expertise to customers.
The program categorizes partners into three types: service, channel, and technology, each further classified into tiers: prime, accelerate, and ignite. Leveraging deep ties with AWS, Microsoft, and Google Cloud, the program aims to expand its reach throughout the ecosystem.
