Marketing Skills for Founders
Marketing Skills gives founders a full marketing team inside their AI agent — 49 open-source skills for positioning, pricing, launches, and outbound, so you can ship growth without hiring yet.
Installs all 49 marketing skills — free and open source
Marketing Skills is a free, open-source library of 49 marketing skills that install directly into Claude Code, Cursor, and Codex. For founders doing marketing themselves, it turns a general AI agent into a marketing team that knows how to build a plan, sharpen positioning, set pricing, run a launch, and send cold outreach — following real playbooks instead of generic filler. You install it in one command (npx skills add coreyhaines31/marketingskills), keep it in your repo, and pull in the exact skill you need for the task in front of you. It's MIT-licensed and works with the AI tools you already pay for, so there's nothing new to buy.
Do the marketing work you can't yet hire for
Most early-stage founders are the marketing team. You're writing the landing page, deciding what to charge, planning the launch, and firing off the first cold emails — usually between building the product and talking to customers. A general AI agent will help, but it defaults to bland, safe output because it has no opinion about how marketing actually works.
Marketing Skills gives your agent that opinion. Each skill is a structured playbook — positioning frameworks, pricing models, launch checklists, outbound sequences — so when you ask for help, you get a plan a real marketer would recognize, not a listicle.
- Turn a vague idea into a concrete marketing plan with owners and sequencing
- Pressure-test positioning and messaging before you commit them to the homepage
- Choose pricing and packaging with a framework instead of a gut guess
- Draft cold outbound that reads like a founder wrote it, not a template
Runs where you already build
The skills install into Claude Code, Cursor, and Codex — the same tools you use to ship the product. There's no separate dashboard, no new subscription, and no context-switching. Reference a skill in your prompt and the agent works from that playbook against your actual product and repo.
Because it's open source and MIT-licensed, you can read every skill, fork the ones that don't fit your business, and add your own. Nothing is a black box, and nothing locks you in.
Prioritize with a marketing brain, not a to-do list
The hardest part of founder marketing isn't executing a tactic — it's knowing which tactic matters this week. Skills like marketing-plan and product-marketing help you set the foundation first (who you serve, why you're different, what to do in what order), so the launch, the pricing page, and the outbound all point the same direction instead of pulling apart.

I'm not a marketer — is this useful if I've never run marketing before?
Yes. The skills encode the frameworks and playbooks a marketer would use, so your AI agent walks you through the decision instead of assuming you already know it. Start with marketing-plan and product-marketing to set your foundation, then pull in launch, pricing, or cold-email as each task comes up.
How do I install it and what does it cost?
Run npx skills add coreyhaines31/marketingskills in your project. It's free and MIT-licensed, and it works inside Claude Code, Cursor, or Codex — the AI tools you likely already pay for. There's no separate product to buy or subscription to manage.
Will it replace hiring a marketer?
It replaces the moment where you'd otherwise stall because you don't have one yet. For the founder-led stage — early launches, first positioning, initial pricing and outbound — it lets you do the work at a higher level. As you scale and hire, the same skills give a new marketer a consistent set of playbooks to work from.
