ClickHouse raised $400 million in a Series D round led by Dragoneer Investment Group, with participation from Bessemer Venture Partners, GIC, Index Ventures, Khosla Ventures, Lightspeed Venture Partners, accounts advised by T. Rowe Price Associates, Inc., and WCM Investment Management.
The latest investment round follows a period of sustained, accelerating growth for ClickHouse. ClickHouse reported that more than 3,000 customers now use its fully-managed service, ClickHouse Cloud, and its annual recurring revenue grew more than 250 percent year over year.
The company said it has onboarded more than a dozen of customers, including Capital One, Lovable, Decagon, Polymarket, Airwallex, Meta, Sony, Tesla, Cursor, and other AI companies.
“ClickHouse was built to deliver exceptional performance and cost efficiency for the most demanding data workloads, and this momentum validates that strategy,” Aaron Katz, the CEO of ClickHouse, said in a statement. Katz said the company is adding support for unified transactional and analytical workloads and expanding into LLM observability so developers can evaluate the quality and behavior of AI outputs in production.
As part of its expansion, ClickHouse also announced the acquisition of Langfuse, an open-source LLM observability platform. “We built Langfuse on ClickHouse because LLM observability and evaluation is fundamentally a data problem,” Marc Klingen, the CEO of Langfuse, said. Klingen said the combined team will focus on faster ingestion, deeper evaluation, and quicker feedback from production issues.
ClickHouse also revealed a new enterprise-grade Postgres service that integrates directly with its analytics platform. The company said the service allows users to sync transactional data into ClickHouse and run analytics up to 100 times faster. The cloud-based service is built in partnership with Ubicloud. “Together, we’re delivering an integrated stack that removes complexity for teams,” Umur Cubukcu, co-CEO and co-founder of Ubicloud, said.
Alongside the fresh funding and acquisition, ClickHouse said it continues to expand globally. The company said it entered the Japanese market through a partnership with Japan Cloud and announced a partnership with Microsoft Azure focused on OneLake. ClickHouse said it also hosted user events across North America, Europe, Asia, and Australia over the past year.
The company said it plans to use the new capital to accelerate product development, expand its cloud offering, and grow its role as a unified data and AI observability platform.
