Claude Code + Codex

Claudex for GTM

Agentic GTM experiments are no longer limited by technical ability. This package shows how Claude Code and Codex can run together to test hypotheses, challenge assumptions, rank Apollo lists, build lead magnets, and keep judgment in charge of what ships.

2x Claude Code for planning and challenge. Codex for build, QA, and package execution.

Tests Run parallel GTM hypothesis tests before committing to one model, one motion, or one channel.

Apollo Turn the winning plan into approved account, contact, list, outreach, and meeting-prep handoffs.

/hypothesis starts in Claude Code with the GTM motion, assumptions, source needs, and risks.
Codex inspects the plan, builds the repeatable package, and checks source quality.
Claude Code challenges the revised plan: weak evidence, buyer mismatch, missing context, and timing risk.
Codex runs final QA against Apollo boundaries, artifacts, and next experiment design.
Your judgment decides what earns the right to ship.

Secure access flow

The full package is protected so the complete Claude Code plus Codex bundle is shared only after approval. Once approved, your team can open the workbench, download the skills, and run the testing workflow with your own GTM context.

What the package does

It is built for GTM teams that want constant testing, not single-model dependency. The point is a reusable system that can read context, ask for missing inputs, run models side by side, rank the right accounts, and prepare clean Apollo-ready execution assets.

Start point:
Start with Claude Code planning, move into Codex build and QA, run adversarial prompting, then push the winning plan into account prioritization, outreach, lead magnet, meeting dossier, and Apollo handoff.

01Claude Code PlansDefine the hypothesis, assumptions, source map, buyer logic, and GTM motion.

02Codex BuildsPackage the workflow, inspect the evidence, rank leads, and prepare artifacts.

03Models ChallengeRun adversarial prompting so weak claims, shallow data, and bad execution paths get surfaced.

04Apollo HandoffMove approved outputs into list, outreach, lead magnet, meeting dossier, and analytics handoff.

Model-to-model testing

The pack lets Claude Code and Codex test the same GTM hypothesis from different angles, then turns disagreement into better operator judgment.

Approval boundary:
The workflow can prepare enrichment, list work, record updates, and existing sequence membership guidance. It does not claim send execution, net-new sequence builds, unsupported batch changes, or unattended writebacks.
