# Y Bombinator

> AI agent that audits Y Combinator applications by calculating founder scores, validating market math, and predicting acceptance chances.

Y Bombinator is an AI-powered audit tool designed to help startup founders improve their Y Combinator applications. Built by entrepreneurs who have experienced YC application rejections firsthand, the tool provides independent assessments based on YC alumni experience. The agent analyzes applications to calculate founder scores, validate market assumptions, and identify competing YC startups to predict acceptance chances.

- **Founder Score Calculation** - The AI agent evaluates your founding team's background, experience, and qualifications to generate a comprehensive team score that reflects YC's evaluation criteria.

- **Market Validation** - Automatically validates your market math and assumptions, helping you identify potential weaknesses in your business case before submitting your application.

- **Competitor Analysis** - Flags competing YC startups in your space to help you understand the competitive landscape and how your application might be perceived.

- **Acceptance Prediction** - Provides a percentage-based prediction of your chances of getting into YC, with approximately 70% accuracy to YC's criteria based on the tool's methodology.

- **Chrome Extension Integration** - Runs through the 100x Bot Chrome extension, allowing you to execute the audit workflow directly in your browser without needing a dedicated application.

- **Featured Showcase** - High-scoring applications can be featured on the platform, providing visibility and potential networking opportunities with other founders.

To get started, install the 100x Bot Chrome extension from the Chrome Web Store. Once installed, run the prompt "execute @workflow:y-bombinator/audit-application" and fill in your startup details in the popup form. The agent will generate a comprehensive audit report with your scores and recommendations. Founders who score above 75% are offered a 1:1 mentoring session.
