Build the company.
Run it from your terminal.
Casa builds the company brief, product diagrams, roadmap, task plan and agent mandates, then routes operating work to specialists and reviews the output. The company brain stays current in your files. It runs inside the agent CLI you already use, on your own plan.

Research, assumptions and decisions shape the company brief.
From evidence to company face
Phase 0 connects the company brief to its product diagrams, operating plan, agent roster and public collateral. Existing companies fill missing foundations without resetting their stage.

One session, end to end
Every session opens on the company, not the chat. Casa reads the brain, names the binding constraint, and ranks what is ready. The walkthrough below is a demo company with synthetic numbers.

- ARTIFACTS

- PROJECTIONS
face.json + attest/
The authored company face and signed CAF record are separate projections of local material.
Optional capx-bind.json records the connection. Private signing keys belong outside the company brain and must never be published with it.

profile.json What the business is and where it stands
build-map.json The applicable playbook graph
ledger.jsonl Append-only record of work and approvals

Departments run on autonomy dials: auto for reversible work, approve-first where you want a look. Action-level hard gates cover spending money, going public, merging to main and destructive changes, whatever the dials say. Approvals land in an append-only ledger.
A company can also exist with no token at all. Attaching one later never changes its identity, history, or URL.
Attestation is local: keygen, attest, sign, check, all offline. caf check is a self-check, not a verdict. Passing means the record is internally coherent and structurally legal. It does not mean the record is true. The public repository also includes an optional hosted integration. Initial binding is go-public consent; a guarded session hook can send new work and an existing face for a bound company. Review that continuing behavior before connecting.
