Claude and Codex as Co-Founders: A Practical AI-First Company Workflow
One tool can hold context and challenge the plan; another can move the work through files and verification.
Anthropic describes Claude Code as an agentic coding tool that can work from the terminal and use project context. OpenAI describes Codex as an agent that helps people write, review, and ship code. Google describes Antigravity as an agent-first development platform that can plan, execute, and verify work across the editor, terminal, and browser.
Those are useful capabilities, but the operating model is more important than the brand names.
Give each partner a job
- Claude can help hold the longer context: research, trade-offs, copy, and questions that need careful reasoning.
- Codex can take a scoped task through files, tests, and implementation while keeping the acceptance criteria visible.
- Antigravity can be considered when a workflow needs an agent-first editor, terminal, and browser loop.
The exact split will change. The invariant is that the human founder owns the problem, the decision, the secrets, and the final review.
The loop we use
Start with a short brief. Ask for risks and missing context. Make one small change. Run the check. Review the diff. Then decide whether the next step deserves another agent turn.
That is why the 2BFT AI-First Company course includes a weekly live session and lifetime updates: the useful lesson is not a static prompt. It is a repeatable way to turn judgment into shipped work.
