Navigate the public YC ecosystem for founder GTM: company research, batch mapping, outreach angles, application positioning, founder network use, and launch leverage. Use when researching YC companies, preparing YC applications, planning YC-style launch motion, or mapping startup ecosystem opportunities.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says

How to install
mdr add leadmagic/gtm-skills/yc-ecosystem@sha256:0ef63da756c72bd6The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
