GTM AI Build Day

One day. Claude Code. Small teams. Real tools.
$ claude "solve my problem"

How it works

👥 Teams of 2–3

Mixed technical + non-technical. Everyone contributes. Non-tech members own the problem & the pitch.

🛠️ One tool: Claude

Claude Desktop, Claude Code, whatever fits. No infra, no frameworks, no setup — just describe what you want to build and iterate.

🎯 Real GTM problems

Build something you'd actually use Monday morning. Content tools, ops scripts, dashboards, automations.

🧠 No coding needed

Claude Code writes the code. You bring the problem, the idea, and the feedback. If you can describe it, you can build it.

🏆 5-min demos

Every team gets 5 minutes to show what they built and why it matters. Judged on usefulness, not complexity.

🚀 Ship to production

Every project can ship. Infra is provided for all teams — if you build it, you can deploy it.
