For whoever is carrying the go-to-market, often alone.

Why it exists

Technical founders and early go-to-market operators are often strong at building or strong at selling, and still stuck on the same questions: who is this actually for, why would those people pay, and what should I work on next. The GTM Co-Founder exists to answer those questions honestly instead of agreeably.

How it works

1. Answer five core questions to create a founder brief.
2. Your agent researches the market you're actually in: the named communities where your users already are, how products like yours launched, and the openings you didn't mention. Every finding is linked.
3. The brief becomes a prioritized go-to-market roadmap: what to work on now, what comes next, and what to park.
4. You work one move at a time, not the whole plan at once.
5. Validated evidence stays separated from assumptions, so you always know which part of the plan is still a guess.

Where it runs

Inside the coding agent you already use. It follows the Agent Skills specification, so it works in Claude Code, Cursor, Codex, Windsurf, Antigravity, and other compatible clients.

What it is not

• Not a course.
• Not a pile of disconnected marketing tactics.
• Not generic chatbot advice.
