Start small.
Don't stay there.

An incubator for AI-native founders ready to boot a promising product up into a real, scalable company.

ERR: BOOT_LOOP

Building got cheap. Growing got harder.

Starting a company has never been cheaper. Growing one keeps getting harder, because markets splinter and attention is scarce. Plenty of good products find a few happy users and then stall.

We think big ideas are still out there, and today's tools make them more reachable than ever. Read the thesis →

THE UPGRADE PATH

Your MVP is the bootloader. Let's load the company.

v0 · prototype

You found demand.

AI tools got you here fast. Good. Now remember: technology isn't a moat. Anyone can clone the features.

v1 · product

Build for scale and security.

A first build is still a prototype. We help you re-architect, harden security and get ready for real traffic.

v2 · company

Go-to-market is the moat.

Positioning, pricing, a first sales motion, and channels that reach the people who pay.

FUNDAMENTALS

New tools. The same fundamentals.

AI changed how fast you can build. It didn't change why people buy.

01
Know your customer
Who has the problem, who pays to solve it, and what they use today. Talk to them every week.
know_your_customer()
02
Reason from first principles
Start from what is true about the problem, not from what competitors are doing.
first_principles()
03
Incorporate feedback early
Put the product in front of users before it feels ready, and let what you learn shape what you build next.

FOR THE BOOTSTRAPPERS

"Pull yourself up by your bootstraps" used to mean impossible.

Founders keep proving otherwise. We celebrate the ones who build with what they have, ship before they're ready, and find a way.

We believe in women founders and would love to work with women building in AI.
