$250M/year Databricks for AI agents
Jan-Erik Asplund
TL;DR: From prompts, tools calls, and traces to evals & cost data, agent telemetry has become the new clickstream, and ClickHouse’s architecture has made it the default observability database for AI companies like Anthropic and OpenAI. Sacra estimates ClickHouse hit $250M ARR in May 2026, up from $160M at the end of 2025. For more, check out our full report and dataset on ClickHouse.
We previously covered ClickHouse in February at $160M ARR as the database for user-facing analytics products & dashboards was getting a foothold in observability.
Key points from our June 2026 update via Sacra AI:
- Built for low-latency queries over extremely large, append-only event datasets like user clicks, pageviews & searches, ClickHouse has become the go-to database for AI agent observability, with customers like using ClickHouse to store, query and debug the explosion in AI agent-generated logging of prompts, tool calls, traces, errors, evals and cost data at 10-20x cheaper than Datadog (NASDAQ:DDOG), which clocks in at $3.67B TTM revenue, up 30% YoY, valued at $83B for a ~23x multiple.
- With top foundation model & AI app layer companies Anthropic ($47B annualized revenue in May 2026), OpenAI ($25B annualized revenue in Feb 2026), Sierra ($200M ARR in May), & Lovable ($500M annualized revenue in May) as customers, ClickHouse has accelerated revenue growth through efficient open-source-to-cloud-hosted funnel and usage expansion on storage & compute, with Sacra estimating ClickHouse hit $250M ARR in May 2026, up from $160M at the end of 2025 (+256% YoY), valued at $15B as of their January Series D (Dragoneer) for a ~94x multiple.
- Through 6 acquisitions in 4 years, ClickHouse has deepened its offering as the agentic AI database via acquisitions of observability platform HyperDX (2025), AI conversation platform LibreChat (2025) & LLM observability platform Langfuse (2026) while adding managed Postgres via PeerDB (2024), mirroring Databricks’s bundling of Neon & Agent Bricks around its data lakehouse ($5.4B annualized revenue in January, +71% YoY, $134B valuation, 26x multiple) and Snowflake’s bundling of Crunchy Data & Observe around its cloud data warehouse ($5B TTM revenue, +31% YoY, $83B valuation, 16.5x multiple).
