About Y Bombinator
By Toolradar Team·
Y-Bombinator is an AI agent, powered by 100x.bot, designed to help startup founders evaluate their Y Combinator application. It provides a clear audit based on criteria derived from the experience of founders who have previously applied to YC, including those who "bombed" multiple times. The tool aims to increase applicants' chances of acceptance by identifying potential weaknesses in their application.
The agent works by having users install a Chrome Agent and then run a specific prompt with their startup's details. It then calculates a "founder-score," validates market math, and flags competing YC startups to predict the application's chances. The service is particularly targeted at YC Spring 2026 applicants and offers a 1:1 mentoring session for those who achieve a score above 75%.
