Overview
The GTM Co-Founder is an open-source set of agent skills for technical founders, especially AI and developer-tool builders who can build the product but get stuck on positioning, first users, launch, pricing, and founder-led sales. The GitHub repository describes it as the GTM co-founder you do not have: a collection of Markdown playbooks that an agent can use inside tools such as Claude Code, Cursor, Codex, Windsurf, Antigravity, or any agent that supports the Agent Skills spec.
Unlike a generic marketing prompt pack, The GTM Co-Founder is designed to create durable working documents inside a founder's project. It starts with a founder brief, turns that into a prioritized GTM roadmap, and then routes the founder through skills for ICP, positioning, launch, pricing, user interviews, sales, content, and measurement.
For solo builders, it belongs in the broader AI productivity and AI workflow generator space, but its real niche is founder decision support rather than task automation.
Key Features
Founder brief workflow - Interviews the founder and creates a reusable brief so later GTM work is based on the actual product, market, and assumptions.
Prioritized GTM roadmap - Turns the brief into Now, Next, and Later moves, helping founders avoid scattered marketing tasks.
Skill-based GTM system - Includes skills for ICP, customer discovery, positioning, first users, launch, pricing, founder-led sales, content, and metrics.
Agent-native installation - Works as Markdown skills that can be copied into ChatGPT-style tools or installed into Claude Code, Cursor, Codex, and related agents.
Developer-tool context - Built for technical founders and dev-tool products, with examples and decision trees closer to developer GTM than generic startup advice.
Open-source MIT license - The repository is public and can be inspected, forked, or customized for a founder's own GTM process.
How to Get Started
The repository offers several paths. The fastest is to open a skill, paste it into an AI assistant, and ask it to apply the framework to your product. The more durable path is to clone the repository or copy the skills/ folder into the agent you already use for product work.
A good first session is not "write marketing copy." Start with the 00-start-here and strategy roadmap flow. That forces the agent to ask the core product and market questions first, then produce a GTM roadmap before any launch post, pricing page, or homepage rewrite.
Founders who already track decisions with an AI agent should treat The GTM Co-Founder as a specialist playbook layer: the coding agent can inspect the repo and product facts, while the GTM skills force it to reason about who pays, why now, and what the next market-facing move should be.
Pricing & Plans
The GTM Co-Founder is open source under the MIT license and free to use. There is no paid software plan in the repository materials reviewed for this page.
The repo does link to human consulting options from the creator's related businesses. Those services are separate from the open-source skill pack and should be evaluated independently if a founder wants personal GTM advice.
Best For
- Solo technical founders building AI, developer tools, open-source infrastructure, or prosumer software
- Builders who can ship code but avoid customer discovery and positioning decisions
- Founders preparing a Product Hunt, Hacker News, Reddit, or community launch
- Developers who want a structured alternative to generic marketing prompts
- Teams using agent skills alongside coding tools like MuleRun or other agent workflows
