Engineering at @ExaAILabs. Previously @square, @plaid.

Unbearably light.

[Jean-Denis Greze 💡 @jgreze]

Today, we’re launching @TownAI: the AI assistant that learns you.

We’re coming out of beta with a $55M Series A led by @ARampell at @a16z, with participation from @KirstenGreen at @forerunnervc and continued support from @firstround, @altcap, and @conviction.

Right now, getting real value from AI means prompting, configuring, building workflows, managing agents.

We think that’s backwards.

The future of AI is a companion that already knows you and how you work. Town connects across your inbox, calendar, Slack, docs, messages, and workflows to understand what you need, then starts doing the work with you.

Drafting. Scheduling. Project tracking. Follow-ups. Context gathering. Multi-step tasks. And it only acts when you say so.

All adapting to your voice, priorities, routines, and relationships over time.

Your Townie is the AI assistant you actually need.

Introducing Exa Monitors - your agent’s radar for the web

Exa is a search engine built from scratch, and today we're exposing our "update" layer. Simply define what to find and how often - Monitors will return any new information, via webhook.

First acquisition lezgo 🚀

[Will Bryk @WilliamBryk]

Exa just made our first acquisition: Browser Buddy

@trillarnie and @jeremyjsuh were working on new types of retrieval to organize the web, so that anyone could find the best blogs and essays.

Now they’re joining Exa to do the same, but for all the world’s information.

They’re two of the smartest and kindest engineers I’ve met, and it’s already been an insane few days working with them.

Here’s to organizing the web together 🍻

[Jeeyoung Kim @jeeyoungk]

When I was young I was a cocky little brat, and I never had an imposter syndrome. I'm only lacking in experience, nothing else.

Now I'm surrounded by smarter, younger, and more energetic people. I only have Experience and nothing else!

Come work with me at @ExaAILabs!

[Will Bryk @WilliamBryk]

The mayor of SF comes by our office all the time.

Unclear if he likes the hedge coffee next door or just really needs a search api

[Jeeyoung Kim @jeeyoungk]

New day, new launch @ Exa!

Introducing Exa Deep: putting an agent inside every search

For each query, an agent runs in a loop until it gathers all information, then returns structured output.

Evals show Deep is Pareto optimal at 4-60s latency, ideal for quick, cost-efficient research!

[Jeeyoung Kim @jeeyoungk]

"git rebase" over "git merge" may be the the center of the midwit meme.

I'm not sure whether I'm on the left or the right of the bell curve though.

[Jeeyoung Kim @jeeyoungk]

I honked at Waymo today. Does that do anything? Does its heart rate go up if it gets honked at?

[Exa @ExaAILabs]

Introducing Exa Instant: the first sub-200ms search engine.

Faster than Google, it's custom built to power realtime AI products like chat and voice.

[Exa @ExaAILabs]

Informed a vendor that we may churn, and we got a box of chocolate.

... Do I need to do this more often?

[Exa @ExaAILabs]

What does it take to store the web as a database?

exa-d is our internal data framework that orchestrates declarative typed dependencies, sparse updates with precise granularity, efficient and parallel execution across scaling compute, and more.
