Your agent ships your product. Now it ships your go-to-market.

Your next customers are one prompt away.

(did I really have to jump off a plane to say that? questionable, but I survived and now you're reading my tweet)

Our Hexa Hacker House SF experiment: give 12 European founders the best possible landing zone in San Francisco.

Results well beyond our expectations:
→ Contracts signed with US customers
→ Investments closed
→ 83% accepted into Y Combinator

Stay tuned for what's to come!

Today a company is run by humans, with AI helping. Tomorrow it's run by code, with humans as tools.

Let's call those: programmatic companies. I think the first one to do $100M in revenue gets founded in 2027. https://t.co/7TDMxd2uhN

🚀 Hexa se lance dans le hardware et la deeptech.

How do you get your first clients in the US?

Tiphaine is doing it right now from Hexa House in San Francisco: showing up in person, building relationships before pitching, and closing deals face to face instead of chasing them over Zoom from Europe.

Follow Hexa for more of how founders actually build in the US.

Why would you need 2 computers to use coding agents?

Charly is a repeat founder building at Hexa Hacker House in San Francisco.
Compilation time was killing his pace; every change meant waiting.

His fix: two computers, each running its own agent, each building a different feature and testing on its own simulator at the same time.

He walks through it in the video; including how he built an MCP server so the agent can interact directly with the app, and why directing agents looks a lot like scaling a team.

Dinner with @OpenAI at the hexa hacker house yesterday night
Told you, @joinhexa is goated ✨🔥

[Pierre Bouquet @pibou_dev]

We made it to the finals of the @agihouse_org hackathon for auto research.

Very lucky to have to work with @voicikatie, @HugooC11, and Sanaa

What do you do when you're forced to pivot?
Meet Riad Eddahabi, one of the founders building at the Hexa Hacker House in San Francisco. He spent years as an early software engineer at multiple healthtech scale-ups, and he's now building his own company in healthcare.

Pivots happen; that's the pace of building in San Francisco, and we expected the same inside the Hexa House. Riad was the latest to go through one.

He walked us through how he validated the new idea fast: 20+ customer interviews in two weeks, no wasted motion.

Follow Hexa for the next episode of our founder learning series, live from the Hexa Summer Hacker House.

Today at the Hexa Hacker House,
we sat down with unicorn founder Nicolas D’Audiffret (founder of Ankorstore).
Nicolas, who’s currently staying at the house with the other founders, shared his advice for first-time founders: when to start, how to run a startup, and why SF is the place to be.

[Hexa @joinhexa]

Meet @pibou_dev, the first of our 11 founders currently at the Hexa hacker house in SF.
Pierre just completed his PhD at MIT, where he worked on the future of work, and is now building in stealth in that space.
Follow us for the reveal of the 10 other founders.

Surprise for our founders at the OpenAI x Hexa Summer Hacker House:

Marie, our chef, to make sure they only have to focus on building!

👇 Why you should be building with other founders

This afternoon we were preparing a cold call session. We coach each other and improve our pitch. Doing it together feels like a fun game, not like a task you have to do. We can see what works for each other and how each persona 'reacts' to the call.

Another experienced founder walks into the room and shares the script with which he was booking 10-15 demos a week. Damn. He got it from a sales performance firm that he was probably paying $2k per month. We get it for free, exactly when we were about to start our calls.

Do you think you experience this when you're building in your room? Hell no.

The environment is everything. Like the harness. Thanks @joinhexa!

Thanks partner in crime @ventiph!
