A decision board for contested calls: feed your agent papers and half-formed ideas, and it files them into a traceable sources → ideas → output structure you can defend, with a visual canvas over the markdown.
The GTM Co-Founder
Summary
An open-source set of go-to-market skills for solo technical founders — positioning, first users, launch and pricing, sequenced into a roadmap your agent works with you.
Features
- Interviews you once and writes a founder brief every other skill reads first
- Reads your repo to pre-fill the brief from what you have actually shipped
- Separates validated facts from assumptions and routes assumptions to user interviews
- Produces a stage-aware Now / Next / Later roadmap that persists between sessions
- 18 skills covering ICP, positioning, first 50 users, launch, pricing and founder-led sales
- A review-the-work gate that stress-tests drafts as a skeptic before you ship
- Self-contained markdown with zero dependencies; also usable by copy-paste

Example Usage
"You are my GTM co-founder. Read my founder brief and give me an honest diagnosis: I have 300 GitHub stars, 40 signups, zero paying users, and I don't know whether to fix onboarding or go find a narrower ICP."
Description
The GTM Co-Founder is a set of MIT-licensed agent skills that put go-to-market strategy inside the coding agent a technical founder already lives in. It is deliberately not a marketing-tactics or SEO pack: it covers the strategy half of GTM — who the product is for, why anyone would pay, and how to land the first users.
How it works
Two setup steps do the heavy lifting. `start-here` interviews you with five core questions and writes a founder-brief.md that every other skill reads first, so advice is about your ICP and your market rather than a textbook's. Run inside your project and it pre-reads the repo — README, recent commits, PR titles, open issues — to pre-fill the brief from what you have actually shipped. It also separates what you have validated with real users from what you are still assuming, and routes the assumptions back to the user-interview skill.
`strategy-and-roadmap` then turns the brief into a one-line diagnosis and a stage-aware plan split into Now, Next and Later, saved as gtm-roadmap.md. That file is the hub you return to each session, so you never reopen a dead chat wondering what to do. The skill is explicitly instructed to offer rather than impose: it will not start a task you have not picked, and anything you decline gets parked instead of resurfacing.
What is in the set
Skills are grouped by the problem they solve, roughly in the order a founder hits them:
- Who it's for —
who-is-this-for,talk-to-users - Say it so it lands —
positioning-and-story,beyond-the-wrapper(for AI products fighting the "just a wrapper" charge),value-prop-that-converts,the-homepage - First users —
time-to-first-value,first-50-users,launch-it,market-to-devs-sell-to-buyers,pricing,founder-led-sales - Keep it going —
founder-led-content,know-if-its-working,market-scan - A gate, not a step —
review-the-work, which makes the agent stop being the author and stress-test a draft as a skeptic before you ship it
Each SKILL.md is written with concrete thresholds rather than principles, decision trees for the calls that stall technical founders, and a checklist you can run in the next thirty minutes.
Provenance and installation
Built by Shane O'Connor from years of selling and advising developer tools, drawing on the work of Adam Frankl and Jakub Czakon. MIT-licensed and dependency-free — every skill is one self-contained folder of markdown, so you can also just copy a file into a chat window if you have never used skills before.
Install with npx skills add AIDevGTM/gtm-cofounder, add the Claude Code plugin marketplace (/plugin marketplace add AIDevGTM/gtm-cofounder), or clone the repository and copy skills/* into your agent's skills directory. Works with Claude Code, Cursor, Codex, Windsurf, Antigravity and any Agent Skills runtime.
