Exa is what I trust for all my agents. We use it at YC. We use it in all my OpenClaw and Hermes Agents. There is no other option that is as fast, as reliable, and as complete.

When your agents need to search the web, accept no substitutes.

Exa raised $250M at a $2.2B valuation, led by a16z, to continue organizing the web for agents:

- Exa now serves search to Cursor, Cognition, Openrouter, 5000+ other companies, 500k+ developers - We’re SOTA in many important verticals (code, companies, people, news, more very soon) - We make agents smarter and cheaper by returning 90% less text with little to no tradeoff in RAG quality - We’re building out web agents that are Pareto optimal on price x performance x latency, possible because we own our search stack fully end to end

We used to tell candidates that without innovation in search, we may live in a world where we have both AGI and fake news. Funnily enough, I think that we’ve now been living in such a world for quite some time. With this funding, we should be able to dramatically improve the state of information in society.

The past 5 years have been a wild ride. Here's where we're going:

btw we did a bake off of Exa vs competitors and it took all of 1.5 hrs for the team to unanimously converge on exa lol.

so proud to see my former landlords crush it - time travel back to last year and listen to a pre pmf @WilliamBryk to understand how to spot companies on a generational tear

Search for agents is not the same thing as search for humans. Agents make *a lot* more searches and they care only about getting the right information. Exa understood this first (2022), built the best product, and is now the clear leader. This is going to be a huge company.

We’re excited to lead Exa’s Series C, to back their ambition of perfecting web search, and making it ready for the age of intelligent agents.

We’re entering a new era for search, built from the ground up around what AI can do.

The signal from the market was consistent. Exa excels with the hardest queries – the long tail of high alpha searches where traditional engines fail. What struck us most was the default behavior: developers and agents are reaching for Exa first.

Years before ChatGPT or the AI boom really started, @WilliamBryk and @jeffzwang were inspired by the transformer breakthrough and believed deeply that AI will fundamentally change the way we access information.

So they set out on the path to build the search engine for a future where agents become the primary consumers of the web.

We’re thrilled to partner with Will, Jeff, and the Exa team as they build the perfect search engine for agents and usher in a world of abundant information for all.

Exa now serves 5000+ companies and 400,000+ developers.

Companies like Cursor, Cognition, HubSpot, and much of the Fortune 500 use Exa for the highest quality search over fresh web data.

Here’s Cognition: “Exa is how Devin sees the web.”

Agents will search the web more than humans this year. Soon it will be orders of magnitudes more.

Nearly every meaningful AI workflow, from coding agents to research systems to enterprise copilots, depends on external information as a core input. For accurate and fast web search, leading AI companies and enterprises rely on @ExaAILabs.

@WilliamBryk and @jeffzwang started building search from the ground up in their Harvard dorm. 5 years later they're becoming the default for developers (and agents) in the AI era.

Thrilled to be leading Exa's Series C and to back Will and Jeff as they build perfect web search for the age of intelligent agents.

It’s been amazing watching this journey.

From metaphor systems to crashing on the company couch. Talking about A100s and rag talks.

This next era is going to be insane. My DMs are open if you want to join us :)

"In the limit, if we could search 100% of the time, we probably would. It just comes down to GPUs, latency, and cost."

Search has become a critical layer of agent infrastructure, and the volume agents drive is orders of magnitude larger than human search ever was.

Exa is becoming the default search engine for developers (and agents) in the AI era, and that's why @sarahdingwang, @JenniferHli, @JasonSCui and I are so excited to partner with @WilliamBryk, @jeffzwang and the @ExaAILabs team!

We are incredibly excited to partner with @ExaAILabs on this next chapter of their journey.

As AI workflows proliferate exponentially, it's clear that web search has become crucial in providing agents and systems access to external info and web data. Exa is on the journey of building perfect search.

The team has made incredible progress so far, and @WilliamBryk and @jeffzwang have been obsessed with search since their Harvard dorm days.

We are so excited to lead their Series C!

We knew serving this world would require building a new search engine, designed for agents.

We train special embedding models for complex queries, track 500B+ urls for the freshest data, and are on our 3rd generation vectorDB for the extreme volume that agents need.
