Dear subway rider,
You might be wondering: how could 1018 be greater than 10100?
Well 1018 as a prefix means Exa. And you know 10100 by its more familiar name: Googol.
Exa is an applied AI lab building a search engine unlike the world has ever seen.
We don't have ads. We sell our search as an API, optimized exclusively for quality, latency, and customizability. That's why customers like Cursor, Lovable, and thousands of others use us to power agents and workflows.
But that's just today. Exa's ultimate goal is perfect search.
What is perfect search? It's simple – you should be able to know anything about the world. Literally anything, like:
- "Find every engineer in NYC who's written a blog post about philosophy"
- "Find all the political clips that went viral in Europe in the past month"
Perfect search is highly controllable, unbiased, comprehensive. Because we lack it, we each walk around with an incomplete understanding of nearly everything.
Building perfect search will be extremely hard. But it's also necessary. It's critical civilizational infrastructure for our new AI reality.
Politics is fragmenting, wars are raging, and technology is accelerating -- we need tools that deeply inform us what's going on. If we don't gain control over the planet's information, we will lose control over our planet.
In short, the world needs perfect search. It needs an organization with pure incentives to build it. And because no one else is doing it, that's why we have to.

How we're doing it
Web-scale infrastructure
Building a search engine from scratch requires building massive-scale infrastructure. There are 100s of billions of webpages (roughly an exabyte!) that need storing, processing, indexing, and serving at high throughput.
Building this is fun but quite difficult. That's why search tools, like ChatGPT, rely on 3rd party search engines under the hood.
Novel neural search architectures
We train novel architectures for web search using end-to-end neural networks. Unlike keyword methods, neural methods get better with more compute and will win in the long run.
We're lucky to now own hundreds of H200s worth of research compute... also known as our exa-cluster :)
World-class team
We've been assembling some of the smartest engineers, researchers, and operators in the world to build the best search engine in history.
We've raised over $100M from top investors including Benchmark, Lightspeed, Nvidia, and YC, and are advised by top researchers from OpenAI, Google, and Bing.
We are hiring across all roles — join our mission.
