Most marketing stacks are a Frankenstein of disconnected tools. **One platform for content, another for leads, a third for outreach, a fourth for newsletter.** Nothing talks. The data dies between every step.

MarketingOS is the actual *pipeline* we ran at OsmoSync to generate 2.2M+ impressions and 20,000+ leads in the last 12 months, open-sourced. Four stages connected end to end. Real code, not prompts.

## What is inside

Four stages, each one feeding the next. Every module works standalone, but they connect into a full pipeline when you need it.

- **Market.** Content frameworks built from 20,000+ posts of algorithm data. LinkedIn, repurpose, YouTube, SEO modules.
- **Convert.** Raw lead dumps in, ranked ICP-qualified pipeline out. Normalize, dedup, enrich, filter, route.
- **Engage.** Outreach that does not read like ChatGPT. Call plus email plus SMS as one coordinated touchpoint.
- **Nurture.** Catches the buyer who does not convert today. Welcome sequences, engagement scoring, newsletter sync.

## Get running in five minutes

**Zero API keys required.** The core pipeline runs on local CSV data. Clone the repo, run `make normalize` to clean any messy lead file, `make filter` to apply your ICP, `make check-copy` to scan outreach for AI patterns. Python 3.9+, stdlib only for the core.

## Who this is for

Founders who are tired of **paying for fifteen tools and still doing the work by hand**. If your lead data lives in CSVs and your outreach reads like a template, this is the spine that connects content, pipeline, outreach, and nurture into one system.
