What do OpenAI, Anthropic, Tesla, Cloudflare, Meta, Canva, Shopify, Harvey, & Ramp all have in common? They're all built on
@ClickHouseDB.
Here's the simplest way I can explain what ClickHouse does: imagine asking a question about every transaction your company has ever processed and getting the answer before you finish reading this sentence. That's ClickHouse.
I sat down with CEO
@ceo_clickhouse and VP of Product
@tbragin to tell the ClickHouse story... because once you understand what they've built, the opportunity becomes impossible to ignore. I believe this is a generational company that will (continue to) power the leading AI businesses.
My biggest takeaway from my conversation w/ Aaron & Tanya:
Every company in the world is rearchitecting around AI. But ClickHouse is what AI is architecting around.
As Aaron put it: "Most infrastructure companies were designed before the emergence of agentic systems. These legacy platforms simply weren't designed to meet the volume, concurrency, and dynamic load these AI workloads demand. ClickHouse was designed for this moment."
I've been an investor since the Series C, and I wanted to write a piece that explains the massive opportunity ahead — and what they've actually built — in plain English.
In this piece, I'll cover how:
→ ClickHouse built the world's fastest analytical database — milliseconds where it used to take hours, at 50-70% lower cost than the tools it replaces.
→ ClickHouse is consolidating the entire data stack — replacing five or more separate vendors: Snowflake, Datadog, Elasticsearch, Pinecone, and Postgres.
→ ClickHouse has built the "Agentic Data Stack" — connecting AI agents directly to real-time data so teams can query, reason, and act instantly.
→ ClickHouse has a credible path to $100Billion — with a trillion-dollar addressable market and a consumption model that scales with every agent deployed. There's a reason ARR has grown 250% YoY with no SDRs, and enterprise customers have grown from 3,000 to 4,000 in just three months 🤯
Thanks for letting me tell this story, Aaron & Tanya.
Let's Click into it…
