Product @ClickhouseDB, fmr @getArctype (acq. ClickHouse), crossed the world by motorcycle in a past life. All opinions are my own. 🇺🇸 🇰🇬 🇨🇳

One of the most-requested ClickHouse Cloud features just hit public beta: executable UDFs.

Write a Python function, zip it, deploy it to your cluster, call it like a built-in. A single DDL statement binds your Python to the data layer.

Next month marks 10 years of @ClickHouseDB as an open source project and we are thrilled to welcome our community at our annual user conference today in San Francisco.

To everyone who contributed code, filed an issue, or ran ClickHouse in production from the beginning: thank you.

Today, we’re proud to share that ClickHouse has over 4,000 customers, passed $250M in ARR, and is trusted by teams like @AnthropicAI, @OpenAI, @cursor_ai, @Lovable, @vercel and many more building the future of AI.

In this post, I cover the milestone, what we’re shipping, and what comes next:

Both OpenAI and Anthropic are now using ClickHouse for observability.

Clickhouse has the potential to become as big as Databricks, which is currenty valued at $134 billion.

$NBIS owns 25% of Clickhouse.

How can you be bearish on $NBIS?

[Ren @ren_stocks]

$NBIS JPMorgan’s observability expert flagged OpenAI moving logs to ClickHouse (28% owned by $NBIS) as a notable defection from Datadog at hyperscale.

OpenAI defects from Datadog to ClickHouse because log ingestion + retention at scale is too expensive on third-party platforms. Nebius rips the

Bullish for $NBIS

[Daniel Romero @HyperTechInvest]

OpenAI is transitioning away from Datadog and into ClickHouse services, where $NBIS holds a 25% stake

[Aaron Katz @ceo_clickhouse]

"The AI bear case for @Snowflake revolves around differences in human vs. agent preferences for accessing data and the continued march of infrastructure that prices to one paradigm becoming obsolete as the world advances. In particular, while Snowflake's query engine works very well at human speeds (loading a dashboard, running a complex SQL query) upstarts like @ClickHouseDB ... argue that agents have very different preferences and prefer lightning fast queries that would be very expensive on Snowflake." 👏

Why does the DOJ continue to take down Epstein files? Who is directing this? Who are they protecting?

At ClickHouse, "impossible" is just another data problem waiting to be solved.

To prove it, we decided to complete all 12 days of the 2025 Advent of Code challenge unconventionally. No Python, no JavaScript, no "real" programming languages. Just pure ClickHouse SQL 🚀

Curious how we did it? Read the blog here 👉 https://t.co/03ITovJP4O

The open-source Agentic Data Stack is here 🔥

👉 https://t.co/bDgxfjdhJy

Today, we’re excited to share that we’ve joined forces with @LibreChatAI. Together, ClickHouse and LibreChat form the foundation of the open-source Agentic Data Stack, empowering teams to deploy AI agents that analyze and act on large datasets through natural language.

And it’s already powering real-world applications:
⬩@Shopify uses LibreChat internally with 1000+ custom agents and 30+ MCP servers
⬩@DaimlerTruck has deployed LibreChat company-wide for secure AI access
⬩@cBioPortal built a public genomics research agent for cancer data analysis on top of ClickHouse and LibreChat
⬩We deployed a LibreChat-backed agent that now handles approximately 70% of data warehouse queries for over 200 users, processing 33 million LLM tokens daily

What doesn't change:
✓ LibreChat remains 100% open source (MIT license)
✓ Community-first development continues
✓ Your existing LibreChat deployments work exactly as before

What gets better:
✓ Enterprise-ready features for production agentic analytics workloads
✓ Native LibreChat experience alongside ClickHouse Cloud instances
✓ Extended data visualization support, enterprise-grade security and governance, and a tailored semantic layer

The future of data analysis isn't dashboards, it's agents that understand your questions and deliver answers instantly from billions of records.

Welcome to the LibreChat team and community! 🎉
