Building a Brain Rot IDE | Clad Labs YC F25

From middle school basketball teammates to Y Combinator founders building the world's first "brain rot IDE," Kevin and Richard's journey is a masterclass in persistence, pivoting, and having fun while building. We discuss: * How they met in middle school and reconnected to start building * Richard's seven YC applications (and why only the last one counted) * Getting rejected with "I hate this idea" and coming back stronger * Building to 1.5M users, then pivoting 24 hours before their YC interview * Why iteration speed matters more than coding speed or sales velocity * Skipping ad impressions entirely and going straight to user acquisition * The Chad IDE: integrating Tinder, TikTok, and gambling into your coding workflow * Hiring two interns during YC and why they took the risk * Why having fun is their most important metric * Real advice: sell before you build, just do it, don't overthink frameworks If you're a startup founder, someone who's applied to YC, or just love hearing authentic stories about the messy middle of building, this episode is for you.
