Rung 1 of 5 . Free and open-source
You believe the source code is more credible than the marketing site. You are right.
Infinite Brain OS is the architecture pattern every Company Brain is built on, fully implemented, fully open. Clone, read, run, fork. MIT-licensed. Live on GitHub.
What is in the repo
The architecture pattern, fully implemented.
Production-grade, MIT-licensed, open to fork. The same pattern that powers paying client builds.
01
Full reference architecture
The knowledge-graph structure, entity types, and validation gates behind every delivered brain. The same architecture that powers paid engagements.
02
Working agent workflows
Claude Code and Codex agent loops you can fork, configured against the reference structure. Run one against your own data in about 30 minutes.
03
The principles, documented
Architecture rationale, decision logs, design constraints, and a public roadmap. The standard is built in the open, and the issue tracker is your path to influencing it.
The principles in code
Three themes. Nine principles. The repo is the proof.
You own everything.
- GitHub is the source of truth. Every change auditable.
- Isolated GCP project per company. No comingling.
- Self-maintain whenever you want. Migration is mechanical.
It is portable forever.
- Open-source primitives: fork, self-host, migrate.
- Tool-swappable: swap one tool without rewriting the stack.
- Model-agnostic: swap the model layer as the frontier shifts.
We empower, never replace.
- Default headless: results, not screens.
- Problem-first design: listen, design, show, then build.
- Your team is the hero. They own the final project.
Honest about the ladder
Why you might not need the paid rungs.
If you can clone the repo, read the architecture, and build your own brain from it, you do not need to pay anyone. The repo is the pattern; the paid rungs are speed and delivery. DIY costs an internal champion months of focus. The Company Brain build is the same pattern, delivered in 14 days by the team that has shipped it repeatedly. If you have the person and the patience, take the repo with our blessing.
Skool is the rung between: a structured curriculum plus community for operators becoming power users of the tools the repo runs on.
The naming
One framework, distinct names.
| Name | Slot |
|---|---|
| Infinite Brain OS | This repo. The open-source implementation of the pattern. MIT-licensed. |
| Company Brain | A Company Brain is one company's private, owned instance of the Infinite Brain pattern: that company's documents, SOPs, workflows, and decisions structured as plain files it owns, which its AI tools read before they answer so every answer is specific to that business and cites its source. We build one in 14 days. The full definition lives at /what-is-a-company-brain. |
| Infinite Entry | The published quantitative spec for AI-era business intelligence. The whitepaper. |
| StarMynd ABI | The commercial data layer. AI-ready business data in a GCP project you own. |
| StarMynd | StarMynd is the company that grounds a business's AI in that business's own data: it builds the qualitative half as a Company Brain, adds the quantitative half as the StarMynd ABI data layer, and maintains Infinite Brain OS, the open-source pattern both are built on. |
The two names people most often merge: Infinite Brain OS is the free open-source product, and a Company Brain is one company's private instance of the same pattern. A Company Brain is not a paid edition, a rename, or a hosted version of this repo, and it does not include the ABI data layer. The repo stays free either way.
