# Yalc > Yalc is an AI native GTM operating system that B2B revenue teams run from Claude Code. It replaces Clay, Outreach, Salesloft, and the rest of the SaaS GTM stack with markdown configured skills. Operated in production by Earleads. CLI first. Yalc lives on the operator's laptop, uses their data, and gets smarter every time it is used.

Yalc runs locally with Claude Code; Clay is SaaS with credit metering - Yalc skills are markdown files you read, edit, and version control; Clay tables and Outreach sequences are vendor configs in their UI - Yalc connects to your existing tools (Crustdata, Unipile, Notion, Instantly) instead of replacing them; Outreach pushes you to use its sequencer - Yalc has no per credit pricing or vendor lock in; the source is on GitHub under a permissive license ## Built and operated by Othmane Khadri, founder of Earleads. Yalc is run in production across the Earleads client book, including Reddit GEO, lead qualification, LinkedIn outbound, and SEO motions. The paid implementation is delivered by the same team. - [GitHub](https://github.com/Othmane-Khadri/YALC-the-GTM-operating-system) - [LinkedIn](https://www.linkedin.com/in/othmane-khadri) - [Earleads](https://earleads.com)
