The open startup repo — everything a founder needs to start and run a company in the agentic era: the comprehensive founder processes from an agentic lens, open documents, situations founders might find themselves in, law that governs the business logic, startup lore, open modules, artifacts and schema.

← Building the product

In simple English

Starting a company involves legal paperwork, cap tables, tax rules, and vendor choices. This repository collects all those processes into one place for founders and AI agents. It includes rankings of business software, math formulas for cap tables, and legal reference notes. You can read the data online or install the command-line tool to let an agent run these steps for you. The code is free to use under an open-source licence, but bulk reuse of the research data requires permission.

What it is

Ultrametric is an open-source repository of startup processes, vendor rankings, business calculations, and legal rules. It provides structured data and a command-line tool designed to help founders and automated agents run a company.

What it is good for

Solo founders and developers who want to automate startup administration or check vendor tools for AI compatibility.
