Build a CompanyOS.

Your backoffice, on autopilot. One Saturday in Stockholm to build the thing that does the recurring work while you sleep.

Sign up

Take a seat.

Registration runs on Luma, so the calendar invite lands straight away and you get a reminder before the day. We mail the address to everyone signed up the week ahead. We need a rough headcount to order the right amount of food, so if something comes up at the last minute, cancel there and the seat goes to someone else.

Questions? Ask in our Discord

The premise

A company runs on work nobody wants to do.

Bookkeeping, invoices, supplier bills, payroll, VAT, the monthly numbers. Today a founder does it by clicking through five systems that were designed for a person with a mouse. A CompanyOS is what you get when an agent does that work instead and a human only approves it.

Build all day, show it in the evening, three minutes of running code and no slides. No judges and no scoring. Lunch, dinner and the bar are on us, and a live jazz trio plays afterwards. Turning up without an idea and joining a team on the day is completely normal.

Our API and our MCP server cost nothing and need no partner application, and the source is open under AGPL-3.0. What you build is yours. Want a head start? The docs are up already: API and MCP, and the source is on GitHub.
