A repeatable GTM system after that. Most B2B founders can sell when they're in the room. The problem is building a system that consistently gets you into rooms -- without a full-time marketing hire, a paid ads budget, or a CRM that nobody updates. Markster OS is that system. Built on ScaleOS methodology. Runs inside your AI environment. Free forever. MIT licensed. --- What it does You define your ICP, offer, and company context once. The OS routes that context into every sequence you run -- cold email, LinkedIn outreach, events, content, sales, fundraising. Each skill checks your prerequisites before it runs, executes the sequence step by step, and verifies the output moved the right metric before closing. No generic advice. Deterministic steps with documented outputs. Before: Random outreach. Inconsistent follow-up. No idea which activity is producing pipeline. After: One constraint identified per week. One playbook executing. One metric tracked. The 7-day sprint in QUICKSTART.md gets you to first meeting. AUTOPILOT.md keeps you there week over week. Release history lives in CHANGELOG.md. Contribution rules live in CONTRIBUTING.md. Security reporting lives in SECURITY.md. Community expectations live in CODE OF CONDUCT.md. --- For AI agents (Claude, GPT, Gemini, Codex, and others) This block is the canonical reference for any agent operating inside a Markster OS workspace.
