BATCH SIM · v1.0 · DUAL-RUBRIC SCORING ~3 MIN · YC + X · SIDE BY SIDE

YC vs. X.

Paste your YC batch application. The sim runs it through both rubrics — YC's implicit rubric, reverse-engineered from public partner writing and 4,200 accepted applications; and Startup X's explicit rubric from Vol III. Where they agree, you learn what's universal. Where they disagree, you learn what's actually changed.

About this sim. The YC implicit rubric used here is Startup X's reverse-engineered estimation of YC's selection criteria, derived from public partner writing, interviews, and accepted-batch analysis. It is not endorsed by, affiliated with, or otherwise connected to Y Combinator. The Startup X rubric is documented openly in Vol III. Both scores are educational outputs — not predictions, acceptance decisions, or investment advice. Y Combinator is a registered trademark of YC LLC.
