Open-source marketing system designed for coding agents
Why would you build marketing processes from scratch when you can install a battle-tested, self-improving marketing system in 15 minutes?

Tell your coding agent the system you want to build. Tin builds it with fine-tuned workflows that run every week on your own company data, with evaluation scaffolding and a self-improving loop.
What every system is made of
- Persistent, with scheduled workflows
- It remembers your company and keeps working while you build.
- Hundreds of workflow templates
- Ten systems beyond this one, from paid ads to outreach, each tuned on real projects.
- Your own company data
- The best marketing uses your whole context, and the code is yours.
- MCP or a user interface
- Your agent calls it as tools, and you get a UI where one helps.
- One place to review and collaborate
- Drafts, PRs and campaigns land in one queue you can comment on.
- Evaluations and experiments
- Evaluations keep the quality steady, and each change gets a before, an after and a verdict.
Your coding agent already knows how to use it
Tin is an MCP server. Add it, and whole marketing systems show up as tools next to the ones your agent already has. Ask it how Tin could help your project. It reads the repo and the skills you already use, and answers.
This is a good fit. I read the repo, your Search Console export and the skills you already keep in .claude/skills.
Three systems I would set up:
Your release-notes skill becomes the first step of the content system, so nothing you wrote is lost.
Turn on organic growth first? The first audit takes about four minutes.
A full marketing stack from templates, in minutes
Each workflow is tuned on real projects. Pick a system and its workflows start running on a schedule. More land every week.
The more it knows about your company, the better the marketing
The code is yours, so you can hand it everything a new marketing hire would take months to learn, and give it live access to the same tools.
The more you connect, the more it can do
The next run starts with what you know.
Tin’s growth knowledge, your company context, and the work that comes out of it. Plain files your coding agent can read over MCP.
Keep your instructions, content, research, and outreach together. Every run has something to build on.

Bring your own workflows, or tweak ours
Your skill files become workflows in one command. Ours are text in the repo: change a step, and the next run uses it.
Case study
Claw Messenger gives AI agents an iMessage number. It had five paying customers when we handed it to the system in March. By late July it had 257, and the SEO, outreach, site fixes and weekly brief were all run by the agent.
Open source, Apache 2.0
Read it, run it on your own machine, change a workflow and send it back.
Made by Ege Özgirin, who built AI agents at Oda and then Keke, his own autonomous AI artist, and Emre Şarbak, who helped build social-impact organizations LaunchCode, Kodluyoruz, Patika, Rise In and SuperSense. Marketing is the new bottleneck for people to benefit from technology. That is what we are solving.
Turn your growth team into growth engineers
Our growth engineers set Tin up inside your environment, connect it to your repo and your data, and adapt hundreds of finetuned workflows to the way your team already works. Your team can continue engineering your self-improving growth system through their coding agents.
