About Eleven

The honest status quo, on one page — with everything deeper linked from here.

What this is

Eleven is a group chat messenger for families, communities, and businesses. It exists because a kid couldn’t message their friends without a phone number, an account, or an advertising business attached — that’s the story — and it’s built by two dads who’ve each spent decades making software for the web.

How it was built

Here’s the part that raises eyebrows, so we’ll say it plainly: Eleven went from nothing to a working product — a live service, a web app, native Mac and iPhone apps, end-to-end encryption from the very first message — in about two weeks, built by two people working with AI. An AI fever dream, with a download button.

Why it might matter

The speed is the least of it. The way Eleven is built and run looks like a genuinely new way to make planet-scale software: rapidly, cheaply, and without the usual compromises — on privacy, on efficiency, on who owns the thing. “Looks like” is deliberate: it’s early, and claims that size need checking. So rather than ask you to take the claim, we publish the working — the architecture, the carbon arithmetic, the live fleet — in the pages below.

Two commitments hold it together. Everything is designed to outlive AI: plain, readable code that a small human team could carry on maintaining if AI got expensive or disappeared. And the destination is a co-operative: owned by the people who use and run it, with open books and no exit.
